Brain size of males by race

https://thealternativehypothesis.org/index.php/2016/04/15/brain-size-race-and-iq/

includes this

The third piece of evidence is that the racial gaps have existed for a long time. In fact, based on the data from the tables above, the White/Black brain size gap doesn’t seem to have gotten any smaller during the 20th century.

Long before your 60s immigration acts.

The first thing to note is that brain size in the general population has a heritability of 87%. Thus, almost all the differences between individuals in brain size are caused by genes.

Secondly, we should note that racial brain size differences are present at, and even before, birth.

Keep blaming women though, that’ll help.

We need more direct studies like this. Gestation length and other variables must be accounted.

Menarche and other variables like WHR vary by race in the women too. More studies! MORE!

The manosphere is based on a myth of equalism, it was destined to fail.

Fourthly, racial brain size differences have been found all around the world. For instance, the Beals and Smith data set previously referred to features skulls from over 100 populations world wide. Many of the autopsy studies previously cited were done in East Asia, as were two of the MRI studies. This makes any gene independent cultural explanation less likely.

Fifthly, several studies have shown that mulattoes have an average brain size in between that of Blacks and Whites (Pearl, 1934Bean, 1906). This finding has been established on multiple occasions and is what a hereditarian hypothesis would predict since mulattoes are half White and half Black genetically speaking.

Do studies for other mixes.

Sixth, many traits which tend to co-evolve with larger brains also differ racially in a way that mirrors the body size adjusted brain size patternRushton and Rushton (2003) looked at 37 anatomical features which 3 textbooks on human evolution identified as tending to co-evolve in the hominid line with larger brains. For instance, larger pelvic size tends to co-evolve with brain size so that mothers can give birth to larger brained infants.  Rushton then utilized 5 forensic anthropology textbooks to look at racial differences in these traits. These traits followed the East Asian>White>Black pattern in 25 out of 31 cases. The probability of this happening at random is .000000001.

WHR is important.

Follow the tag, there are racial differences in studies.

And East-Asian isn’t a race, at best it’s a sub-group, do more studies. Properly.
Asians fail more often on IVF, also posted about that.

Similarly, Rushton (2004) showed that, across 234 mammalian species, brain size correlates with longevity, gestation time, birth weight, litter size, age of first mating, body weight, and body length. Various studies have shown that each of these variables also differ between the races in a way that, based on what we find across the animal kingdom, would predict the body size corrected brain size differences we observe (Rushton, 1995Templer 2006Rushton and Templer, 2009;).

Longevity – must look at averages e.g. not Danes for all whites nor Japs for all Asians.
Gestation – we know this varies.
Weight – control confounds.
Litter size – look at natural rate of twinning.
Virginity loss is r-select, do not want.
Body weight – vague.
Length – we already know racial height. Still, add to the rest, I guess.

Thus, we have six lines of evidence all of which would be predicted by a hereditarian view on racial differences in brain size. While each line of evidence on its own may not be compelling, the combination of all six seems to strongly imply that racial brain size gaps are partly heritable.

It is worth noting that the racial brain size gaps are probably not entirely attributable to genes. Some authors, including Richard Nisbett, have plausibly argued that nutrition also plays a role. However, there explanations are not mutually exclusive, no environmental variables has been shown to account for the majority of the gap, and,  as we have seen, there are many separate lines of evidence indicating that genes also play a role

A confound, in weight.

I suggest seafood consumption.

There is good evidence that the races evolved different brain sizes in response to climate. Specifically, various studies have found that a population’s brain size correlates with climate related variables. For instance, Pearce and Dunbar (2011) ‘s data set produces a correlation of .74 between a population’s brain size and its latitude. Similarly, Ash and Gallup (2007) found a correlation of .48 between the size of 109 fossilized human skulls and the latitude at which they were found. Further still, Bailey and Geary (2009) analyzed 175 skulls ranging in age from 10,000 years old to 1.9 million years old and found a correlation of -.41 between brain size and winter temperature and -.61 between size and latitude (larger brains were found in areas more distant from the equator).

How dare you use science.

The weebs might reee!

Lynn (2015) used Smith and Beals data set of 20,000 skulls from 122 populations to estimate that roughly 30% of the African-European IQ gap can be statistically accounted for by brain size differences. By contrast, brain size differences would actually predict an Asian-European IQ gap 35% larger than the one that actually exists. Thus, brain size is probably one of many factors, both biological and environmental, which account for racial intelligence differences.

This explains their lower IQs in many nations, larger overall heads and stronger jaws.

HUGE lips, too.

Naturally the page tries to lie about white people as all magic albinos BUT the Asian part has this:

And morphology considerations:

Of the three crania Upper Cave 101, the “old man”, has been studied in more detail primarily due to its better preservation and clearly adult status. In comparison to modern East Asians the cranial vault is extremely long and low, with a receding frontal squama and marked angulation in the occipital region. The forehead is broad and the supercilliary region well developed. The nasal bones are pinched, with a high bridge, and the nose must have been more prominent than is common amongst living East Asians. The orbits are relatively low and rectangular, which is a common feature in terminal Pleistocene and Neolithic crania from many parts of the world. The lower border of the nasal aperture is gutted, which is customary amongst East Asians, Australian Aborigines and sub-Saharan Africans.

East Asians are just mongrels. They simply didn’t exist as we know them today and the modern Indian is typically a halfbreed with a Brit a century or two ago. This caused their ‘caste’ system.

All analysis of “Early Humans” in China, agree that the Mongoloid type Humans currently inhabiting the area, did not start to appear until quite recently.
But here the devil is in the definitions; we know that modern Chinese (Mongols) are a Mulatto/Mixed Race of Mongol featured Blacks like the San, their Albinos, the Albinos of Central Asians (who later became Europeans), and Blacks like the Jomon in Japan. But understanding just when these admixtures took place requires we know exactly what was meant by “Primitive Mongoloid” or “Evolving Mongoloid” and how is that different from Eskimo? (Not saying that Eskimo are primitive).

Any admixture was usually rape.

As was shown with the Peking man nonsense, many Albino and Mulatto Chinese are loath to admit that they derive from Africans. But the fact is that the Chinese, Japanese, Koreans, and South Asians, have all been scientifically proven to be Africans. Albeit, as is true in many places i.e. the Americas, the Middle East, etc. They are a mixture of Albino people and the original Native Blacks.

I don’t believe albino is a race, it’s a mutant and they’re often sterile.

But Asians do have substantial African morphology, you can see it in their face.

Waist-Hip Ratio and female beauty

The sexual dimorphism for this metric is obviously lowest on Asians.

https://www.ncbi.nlm.nih.gov/pubmed/8366421

Evidence is presented showing that body fat distribution as measured by waist-to-hip ratio (WHR) is correlated with youthfulness, reproductive endocrinologic status, and long-term health risk in women. Three studies show that men judge women with low WHR as attractive. Study 1 documents that minor changes in WHRs of Miss America winners and Playboy playmates have occurred over the past 30-60 years. Study 2 shows that college-age men find female figures with low WHR more attractive, healthier, and of greater reproductive value than figures with a higher WHR. In Study 3, 25- to 85-year-old men were found to prefer female figures with lower WHR and assign them higher ratings of attractiveness and reproductive potential. It is suggested that WHR represents an important bodily feature associated with physical attractiveness as well as with health and reproductive potential. A hypothesis is proposed to explain how WHR influences female attractiveness and its role in mate selection.

Hello sexual selection, tied intimately to natural selection.

PDF here: https://pdfs.semanticscholar.org/05d6/0e201efb208e8561641d13df30fc6ba3bc1a.pdf

also connected to “desire and capability for having childrenp7 or 299.

so K-type women may have better WHR.

Normal weight women have the most positive attributes associated.

Overweight category was universally unattractive.
It’d be nice to see a male study on this. I think Western women would want more children if fewer men were obese.

Why Asians are considered youthful but not sexy (they’d usually fall in the underweight group):

The variables of attractiveness, sexiness, and good health were located close to each other, suggesting that subjects perceived them to be closely related.

Attributes of desire and capability for having children were located close to each other in the solution space but farther from attractiveness, sexiness, and good health, implying that subjects did not perceive a great similarity between these two sets of attributes.

Finally, the attribute of youthfulness was located alone and away from both sets of other attributes. Thus, subjects apparently did not perceive youthfulness to be related to any other measured attributes of good health, sexiness, attractiveness, and desire and capability for having children.

So there’s that. Nobody’s jealous.

Figure N7 was located closer to attractiveness, sexiness, and good health as well as desire and capability for having children than any other Figure.

Normal weight for frame (and race) + most nubile WHR would make sense.
More of those genes survived.

Figure N9 was located closest to desire and capability for having children, whereas Figure N8 was located between Figure N7 and Figure N9. The figure N10 was grouped along with overweight figures, which were not perceived to be closely associated with any of the attributes under investigation. Underweight female figures, U7 and U8, were associated only with youthfulness. However, underweight figures with high WHR (U9 and U10) were perceived as neither youthful nor healthy, in spite of the fact that their depicted body weight was quite similar to figures with lower WHR.

Women with an atrocious WHR (boy hips, no waist) and under or overweight for their skeleton are objectively unattractive from an evolutionary standpoint. This would apply whether it’s a Jap, a Ruskie or an American.

Stop calling sexy science ‘racist’ because it doesn’t share your fetish.

This chart drags you harder than I ever could.

Your Asian girlfriend with the boy hips is approximately as attractive to the world as the average WHR white fat chick. That’s your level, accept it.

It’s also a fact we cannot accurately perceive attractiveness of the racial outgroup as well as our own, so an awareness of ingroup flaws changes nothing.

Most modern women straight up don’t look healthy, whether they’re American, European or, yes, Asian.

Stop trying to make boy hips = sexy happen. It’s not going to happen.

Look at the damn gradient on that underweight thing. The solution to fat women isn’t anorexia. That also suggests bad genes. In fact, at least the fat percentage on slightly overweight 0.7 WHR women suggests femininity and fertility.

“Overall, it seems that subjects inferred reproductive capability from body fat”

What does a foetus feed from?

“Thus, it seems that although WHR is related to health and attractiveness, body weight is perceived to be related to reproductive capability”

Obviously.

“As a group, underweight figures were assigned the lowest reproductive capability, followed by overweight figures and then normal weight figures.”

Suck on that, soyboys.

You actually tend to downgrade. That’s why the Democrat-voting soyboys all want an Asian girlfriend and expressly don’t want kids with it.

“Overall, it appears that both fatness and thinness are perceived as unattractive, and such figures are not perceived as having especially high reproductive potential. “

Not womanly. Remember that word? This:

Not girly, not sexy, not cute, not hot. Womanly.

You can’t discuss women in a reproductive, evolutionary context without it.

Thus, consistent with the present findings, men did not find thin or underweight figures attractive.

If you only care for other male opinions.

There is some evidence that suggests that being extremely underweight or overweight can have adverse effects on female reproductive functions.

Ya don’t say?

A critical body mass has been shown to be significantly related to the onset of menstrual cycle and its maintenance (Frisch & McCarthur, 1974), although recent evidence (DeRidder et al., 1990) suggests that it is the body fat distribution, rather than body fat mass or body weight, that is related to early pubertal development.

Distribution varies by race.

Africans are the most pronounced in women then Europeans shapely but delicate then Asians last – no shape, very yang flesh (broad but flat or full in the middle like cortisol fat) and almost nothing to distribute.

Am I imagining all of this?

Underweight females (15% below ideal body weight) have been reported to have a higher incidence of oligomenorrhea (menses 35 days or more apart) and amenorrhea and to have a higher prevalence of ovu-latory infertility than normal weight females (Green, Weiss, & Daling, 1986).

Underweight women also give birth to infants who are small and growth delayed, and such infants often have permanently impaired intellectual and physical development (Supy, Steer, McCusker, Steele, & Jacobs, 1988).

Menstrual dysfunction and ovulatory infertility also occur more often in females who are 20% above ideal body weight (Green et al., 1986). Morbid obesity in females with high WHR has been shown to increase the degree of androgenicity (increased percentage of free testosterone) and associated menstrual and ovulatory problems (Kirschner & Samojilik, 1991). Thus, the reproductive success of a woman may be low in spite of a high level of fat deposits if the regional distribution of fat is not appropriate, that is, gynoid.

=Womanly.

Finally, the finding that underweight figures were assigned high rankings for youthfulness but not for attractiveness (or other attributes related to reproductive potential) is difficult to reconcile with some evolutionarily based mate selection hypotheses.

Normal men aren’t pedos.

Youthfulness and health have been proprosed as absolute criteria for female attractiveness (Symons, 1987).

Stick with health.

Health has good or bad, you have no negative way to assess youth e.g. immature.

Features of physical appearance associated with youth supposedly provide the strongest and most reliable cues for female reproductive potential. The present finding illustrates that the relationship of youthfulness and attractiveness is quite complex.

Not really.

A woman who is judged to be attractive is also found to be youthful; however, youthfulness alone does not make a woman attractive. Apparently, youthfulness is a necessary, but not a sufficient condition, for determination of female physical attractiveness.

crazed pointing-

also, don’t try to chalk this up to taste:

“Furthermore, if the ideal of female attractiveness is arbitrary and ever changing, no evidence of transgenerational stability in the meaning of WHR should be found, as older men are more likely to be exposed to different ideals of attractiveness than are younger men.”

but

“Older men did not associate health with underweight figures, including those with lower WHR.”

TLDR: Pedos are wrong. Underweight, waistless wonders are not attractive.

Study 2, rubbing salt in that fact.

Optimal Waist-to-Hip Ratios in Women Activate Neural Reward Centers in Men

Secondary sexual characteristics convey information about reproductive potential. In the same way that facial symmetry and masculinity, and shoulder-to-hip ratio convey information about reproductive/genetic quality in males, waist-to-hip-ratio (WHR) is a phenotypic cue to fertility, fecundity, neurodevelopmental resources in offspring, and overall health, and is indicative of “good genes” in women. Here, using fMRI, we found that males show activation in brain reward centers in response to naked female bodies when surgically altered to express an optimal (∼0.7) WHR with redistributed body fat, but relatively unaffected body mass index (BMI). Relative to presurgical bodies, brain activation to postsurgical bodies was observed in bilateral orbital frontal cortex. While changes in BMI only revealed activation in visual brain substrates, changes in WHR revealed activation in the anterior cingulate cortex, an area associated with reward processing and decision-making. When regressing ratings of attractiveness on brain activation, we observed activation in forebrain substrates, notably the nucleus accumbens, a forebrain nucleus highly involved in reward processes.

These findings suggest that an hourglass figure (i.e., an optimal WHR) activates brain centers that drive appetitive sociality/attention toward females that represent the highest-quality reproductive partners. This is the first description of a neural correlate implicating WHR as a putative honest biological signal of female reproductive viability and its effects on men’s neurological processing.

Quality.

Men report stronger attraction to femininity in women’s faces when their testosterone levels are high

Many studies have shown that women’s judgments of men’s attractiveness are affected by changes in levels of sex hormones. However, no studies have tested for associations between changes in levels of sex hormones and men’s judgments of women’s attractiveness. To investigate this issue, we compared men’s attractiveness judgments of feminized and masculinized women’s and men’s faces in test sessions where salivary testosterone was high and test sessions where salivary testosterone was relatively low.

This is why we need studies on men too.

Men reported stronger attraction to femininity in women’s faces in test sessions where salivary testosterone was high than in test sessions where salivary testosterone was low. This effect was found to be specific to judgments of opposite-sex faces. The strength of men’s reported attraction to femininity in men’s faces did not differ between high and low testosterone test sessions, suggesting that the effect of testosterone that we observed for judgments of women’s faces was not due to a general response bias. Collectively, these findings suggest that changes in testosterone levels contribute to the strength of men’s reported attraction to femininity in women’s faces and complement previous findings showing that testosterone modulates men’s interest in sexual stimuli.

Beauty is in the eye of the plastic surgeon: Waist–hip ratio (WHR) and women’s attractiveness

Attractiveness conveys reliable information about a woman’s age, health, and fertility. Body fat distribution, as measured by waist-to-hip ratio (WHR), is a reliable cue to a woman’s age, health, and fertility, and affects judgment of women’s attractiveness. WHR is positively correlated with overall body weight or body mass index (BMI). Some researchers have argued that BMI, rather than WHR, affects judgments of female attractiveness. To evaluate the role of WHR, independent of BMI, we secured photographs of pre- and post-operative women who have undergone micro-fat grafting surgery. In this surgery, surgeons harvest fat tissue from the waist region and implant it on the buttocks. Post-operatively, all women have a lower WHR but some gain weight whereas others lose body weight. Results indicate that participants judge post-operative photographs as more attractive than pre-operative photographs, independent of post-operative changes in body weight or BMI. These results indicate that WHR is a key feature of women’s attractiveness.

Duh.

Trends in waist-to-hip ratio and its determinants in adults in Finland from 1987 to 1997

Background: Although abdominal obesity has been shown to be an important risk factor for cardiovascular disease and a variety of other diseases, secular changes in fat distribution in populations have rarely been documented.

Objective: Our objective was to assess trends in waist-to-hip ratio (WHR) in the Finnish population during a 10-y period. In addition, we investigated the associations of WHR with body mass index (BMI), age, education, and lifestyle factors.

Design: Three independent cross-sectional surveys were carried out at 5-y intervals between 1987 and 1997. Altogether, 15096 randomly selected men and women aged 25–64 y participated in these surveys.

Results: The WHR increased in both men and women during the 10-y period (P< 0.0001). In men, the strongest upward trend took place in the first 5-y period and then seemed to plateau; in women, the WHR continued to increase into the 1990s. In both sexes, the most prominent increase was observed in subjects aged ≥45 y. The WHR increased in all education-level groups, the lowest WHR being among those with the highest education. Age (18% in men, 12% in women) and BMI (33% in men, 25% in women) accounted for most of the variation in WHR, whereas only 3% was explained by education and lifestyle factors.

Conclusions: Abdominal obesity is a growing problem in Finland, especially in persons aged ≥45 y. These adverse changes in body shape continued to take place, particularly in women, in the 1990s.

Preferred Women’s Waist-to-Hip Ratio Variation over the Last 2,500 Years

The ratio between the body circumference at the waist and the hips (or WHR) is a secondary sexual trait that is unique to humans and is well known to influence men’s mate preferences. Because a woman’s WHR also provides information about her age, health and fertility, men’s preference concerning this physical feature may possibly be a cognitive adaptation selected in the human lineage. However, it is unclear whether the preferred WHR in western countries reflects a universal ideal, as geographic variation in non-western areas has been found, and discordances about its temporal consistency remain in the literature. We analyzed the WHR of women considered as ideally beautiful who were depicted in western artworks from 500 BCE to the present. These vestiges of the past feminine ideal were then compared to more recent symbols of beauty: Playboy models and winners of several Miss pageants from 1920 to 2014. We found that the ideal WHR has changed over time in western societies: it was constant during almost a millennium in antiquity (from 500 BCE to 400 CE) and has decreased from the 15th century to the present. Then, based on Playboy models and Miss pageants winners, this decrease appears to slow down or even reverse during the second half of the 20th century. The universality of an ideal WHR is thus challenged, and historical changes in western societies could have caused these variations in men’s preferences. The potential adaptive explanations for these results are discussed.

Should’ve controlled for race.

Why not look at male WHR? Plus sperm health? Found:

https://www.drelist.com/blog/bmi-waist-circumference-semen-quality/

  • The volume of ejaculate decreases in a linear fashion with increasing BMI (suggesting an inverse relationship).
  • The sperm quality and viability declines with increasing waist circumference.
  • Investigators also discovered that quality of semen decreases (such as sperm viability, motility, semen volume) with increasing body size; however, no relationship was observed between sperm DNA fragmentation index and physical activity or obesity.

Latter requires time.

Various research and clinical studies suggests that subfertility in men is multifactorial i.e. several factors can impact the quality of reproductive health.

  • Abnormal sperm production: Study conducted by Jensen and associates (2) suggested that abnormal BMI is very strongly linked to impaired sperm production. One of the many reasons is, abnormal metabolism of testosterone (which plays a key role in the production of healthy and viable sperms).
  • Abdominal obesity and risk of metabolic disorders: According to a new study reported in the Human Reproduction (3), investigators provided statistical evidence that abnormal BMI and abdominal obesity is very strongly linked to a number of health issues (such as cardiovascular dysfunction, atherosclerosis, type 2 diabetes, hypertension and others). Needless to say that these health issues have a deleterious effect on the sexual health regardless of the body-mass index (or BMI).
  • Obesity, physical activity and testosterone: Testosterone levels tends to decline in males who have a sedentary lifestyle. Various research and clinical studies indicates that aerobic activity or exercise can improve testosterone metabolism in males significantly.

Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces.

Both attractiveness judgements and mate preferences vary considerably cross-culturally.

Racially.

We investigated whether men’s preference for femininity in women’s faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of men’s preferences. Using an average femininity preference for each country, we found men’s facial femininity preferences correlated positively with the health of the nation, which explained 50.4% of the variation among countries. The weakest preferences for femininity were found in Nepal and strongest in Japan. As high femininity in women is associated with lower success in competition for resources and lower dominance, it is possible that in harsher environments, men prefer cues to resource holding potential over high fecundity.

Asia is weird for dimorphism studies.

Hence the focus on health.

While the economy is bad, it isn’t surprising men prefer manly looking women.

It’s temporary. There’ll be a flood of divorces as the economy improves. Men will suddenly see how mannish the wife has been and be repulsed. Menopause also makes women look more mannish, including higher WHR. So much for a youth argument there.

Factors Underlying the Temporal Increase in Maternal Mortality in the United States

They don’t say more non-white mothers or more mixed race babies, so it’s wrong. They guess.

What makes a species classification?

Assuming you’ve read previous links about mixed race fertility issues and health problems.

https://phys.org/news/2019-01-species.html

“Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won’t* or can’t mate with one another, or, if they do, the resulting offspring are often sterile, unviable, or suffer some other sort of reduced fitness.
In a new paper published in the journal eLife, the researchers show that sex chromosomes evolve to be genetically incompatible between species faster than the rest of the genetic chromosomes and reveal the factors at play in this incompatibility.

*White women are a different species?

True.

So sexual repulsion is part of species classification.

https://phys.org/news/2016-03-sex-evolve-prof-laurence-hurst.html

“This variation is manifested at the genetic level: sex generates some organisms within the species with lots of harmful mutations and some with relatively few. Supporters of the so-called mutational deterministic theory argue that if organisms with many mutations have disproportionately low survival chances, many bad mutations tend to die out with their hosts, generating a large number of organisms that are free from such mutations.”

“This sort of evolutionary game of cat and mouse is known as Red Queen evolution, from the character in Alice in Wonderland who insisted that one must run just to stay in the same place. Indeed, genes related to immunity are some of the fastest evolving we have. There is also recent evidence that species can increase the amount of genetic mixing they do when they sense that they are infected with a parasite. This means their offspring will be even more different from one another and their parents.”

Hard times make strong men.

https://phys.org/news/2018-11-human-evolution-possibly-faster.html

“But neutral evolution can’t explain why some genes are evolving much faster than others. We measure the speed of gene evolution by comparing human DNA with that of other species, which also allows us to determine which genes are fast-evolving in humans alone. One fast-evolving gene is human accelerated region 1 (HAR1), which is needed during brain development. A random section of human DNA is on average more than 98% identical to the chimp comparator, but HAR1 is so fast evolving that it’s only around 85% similar.

Though scientists can see these changes are happening – and how quickly – we still don’t fully understand why fast evolution happens to some genes but not others. Originally thought to be the result of natural selection exclusively, we now know this isn’t always true.”

“The human mutation rate itself may also be changing. The main source of mutations in human DNA is the cell division process that creates sperm cells. The older males get, the more mutations occur in their sperm. So if their contribution to the gene pool changes – for example, if men delay having children – the mutation rate will change too. This sets the rate of neutral evolution.”

I have covered paternal age before. Few times.

Men delaying fatherhood is killing the West more than low birth rates. Having a few sprogs when you’re older only works if they’re higher quality than you could’ve had earlier.

Although obviously the birth rate CANNOT rise without marriage rates rising first.

“The researchers also found positive selection in four pigment genes important for lighter skin in Europeans that were not known before. Scientists think humans evolved lighter skin in Europe as an adaptation to less sunlight.”

“And in East Asians, they found strong evidence of positive selection in genes involved in the production of alcohol dehydrogenase (ADH), a protein necessary for breaking down alcohol. Many East Asians can’t metabolize alcohol because they carry a mutation that prevents them from making ADH. The new finding suggests that the mutation may confer some currently unknown additional benefit.”

naturalistic fallacy, mutations can hold you back too

for example, if being able to produce it made you more prone to alcoholism, a disadvantage

“The findings suggest that about 9 percent of the human genes examined are undergoing rapid evolution.

“Our study suggests that natural selection has played an important role in patterning the human genome,” said Carlos Bustamante, a biologist at Cornell University.

A separate study announced last month indicated the human brain is still evolving, too.

Compared to chimps …”

If there’s reproduction, there’s evolution.

BC mutation.

Another 13 percent of the genes examined in the study showed evidence for negative selection, whereby harmful mutations are weeded out of the population. These included some genes implicated in hereditary diseases, such as muscular dystrophy and Usher syndrome. The latter is the most common cause of congenital blindness and deafness in developed countries.

Medical geneticists are interested in finding genes sensitive to negative selection because they might one day be useful for predicting an individual’s likelihood of developing a disease if the types of mutation to a gene and the environmental conditions are known.

Being able to determine which classes of genes are particularly vulnerable to negative selections is a first step, Bustamante said.”

“A newly-discovered species of ant supports a controversial theory of species formation. The ant, only found in a single patch of eucalyptus trees on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development.

Nope!

“Most new species come about in geographic isolation,” said Christian Rabeling, assistant professor of biology at the University of Rochester. “We now have evidence that speciation can take place within a single colony.”

The findings by Rabeling and the research team were published today in the journal Current Biology.”

B-b-b-but…

Where’s the evidence?

Outbreeding depression

There need to be more studies on this but I know scientists are busy with buttered toast experiments and rating their own farts.

This is the genetic thing you never hear about, despite everyone and their purebred* dog knowing about inbreeding depression.
Hybrid vigour doesn’t even apply to modern wheat.

And hybrid is misused.

I saw this explanation:

A hybrid is a cross between two closely related strains such as an Arab and a Jew or a Swede and a Spaniard. A mongrel is a cross between different races such as a Mulatto, a Mestizo, a Eurasian, etc.

Positive outbreeding studies are conducted on flies.
https://link.springer.com/article/10.1023/A:1024081416729

…I don’t even, insects are already heavily inbred by default so outbreeding isn’t really possible.

Outbreeding depression is more of an issue than inbreeding (some inbreeding is good for a gene pool, the most fertile and healthy couple combinations and normal historically), which is fixed by breaking the pattern for a few generations. However, you cannot undo outbreeding depression in part due to its novelty. It’s easy to add, impossible to take away.

Actually it’s the combination of genes that makes the organism unfit.

Its ideal environment doesn’t exist. In any other environment, it’s defective.
In the race for life, they’re disabled. It’s like mixing wines, they lose their distinctive character but other examples haven’t. In a competition…

Easy example:

One nose selection gene for cold weather, one selection for hot.
Result: poorly adapted child for either.

Paper: Race: A social destruction of a biological concept

https://www.researchgate.net/publication/225799711_Race_A_Social_Destruction_of_a_Biological_Concept

It is nowadays a dominant opinion in a number of disciplines (anthropology,
genetics, psychology, philosophy of science) that the taxonomy of human
races does not make much biological sense. My aim is to challenge the arguments
that are usually thought to invalidate the biological concept of race. I will try to
show that the way ‘‘race’’ was defined by biologists several decades ago (by
Dobzhansky and others) is in no way discredited by conceptual criticisms that are
now fashionable and widely regarded as cogent. These criticisms often arbitrarily
burden the biological category of race with some implausible connotations, which
then opens the path for a quick eliminative move. However, when properly
understood, the biological notion of race proves remarkably resistant to these
deconstructive attempts. Moreover, by analyzing statements of some leading contemporary
scholars who support social constructivism about race, I hope to demonstrate
that their eliminativist views are actually in conflict with what the best
contemporary science tells us about human genetic variation.

Britons little changed in DNA since Ice Age

https://news.nationalgeographic.com/news/2005/07/0719_050719_britishgene.html

Despite invasions by Saxons, Romans, Vikings, Normans, and others, the genetic makeup of today’s white Britons is much the same as it was 12,000 ago, a new book claims.

In The Tribes of Britain, archaeologist David Miles says around 80 percent of the genetic characteristics of most white Britons have been passed down from a few thousand Ice Age hunters.

Note the precision of language. That is a scientist.

Technically, there’s no such thing as British.

There was no British Empire, it was the English Empire. You didn’t see the Welsh fucking up anyone.

Despite all the Guardian articles trying to make out we were awful, the People aren’t fooled.

https://www.independent.co.uk/news/uk/politics/british-people-are-proud-of-colonialism-and-the-british-empire-poll-finds-a6821206.html

 

YouGov found 44 per cent were proud of Britain’s history of colonialism while only 21 per cent regretted that it happened. 23 per cent held neither view.

The same poll also asked about whether the British Empire was a good thing or a bad thing: 43 per cent said it was good, while only 19 per cent said it was bad. 25 per cent responded that it was “neither”.

Americans don’t understand how political and meaningless the term British is.

Since the collapse of the Empire, it’s been meaningless.

People are either English, Welsh, Irish or Scottish. Sometimes a combination.

There are also little islands like Jersey that have their own flags.

Cooler than ours but derived from England’s original Three Lions heraldry.

The British is typically, Great Britain, and the union of the four countries is incredibly recent (Union Act 1707, 1800). It’s a term about what the Queen owns, similar to the UK but without pesky parts of Ireland.  Jane Austen’s novels are older than Great Britain. England is a country in its own right, Parliament and the Queen are based there. It’s the central country.

The British Isles covers the most landmass. It’s huge. It’s geographic and includes a lot of tiny islands.

So again, if you’re discussing where a person is from, to say they’re from Britain is technically incorrect. At least, what Britain? Great? Isles? What? It’s like saying someone is European, unless you mean the continent (correct but vague) you cannot mean the legal construct (EU) because nobody’s DNA originates from a legal fiction. There is no such physical PLACE. There is no DNA for Britain, (sometimes ancient Briton, as in the study above) but it’s either English from England, Irish from Ireland, Scottish from Scotland or Welsh from Wales. British is meant to be from Britain but nowadays everybody has a British passport, a passport grants citizenship and financial entitlements it changes nothing about your DNA. To refer to blood, genes and ancestry, you cannot be British. It would be like referring to your occupation, it’s a legal thing.

Recently they’ve tried to claim dilution.
