By definition, two species cannot breed (naturally, don’t @ me with IVF ‘struggles’). It’s been found genetically before that speciation is increasingly occurring between the modern human races. This happens to all races and is how species are formed.
“Far from established fact” it’s literally the Darwinian meaning of the term. If you misuse it, you are just wrong.
Two races? Yes. I’m hardly shocked at the race denialism. The proof is right there, you are wrong.
I’m not shocked the hybrids died out, likely from infertility or childbirth deaths.
It’s been well known there was interbreeding in the edges of Europe.
However, notably, they are the ones who DIED aka the most unfit. Nobody seems to be mentioning they were abnormal. Or we wouldn’t have found them in a mass grave, abandoned. By BOTH sides of kin. (Parents still abandon their ugly children.)
Why do they use black photos, when none of the samples were African?
And when it’s a white person, why always a fug ginger? Why no brunettes or blondes? Too afraid to make em hot?
The cave in question is in the Siberia, Russian area, so this is one of the few places whites could’ve interbred with Asians.
No wonder they died out. Nobody else wanted them. It’s been proven humans prefer averageness aka in-group looks. Only the rejects go for exotics. It isn’t surprising at all they found such a girl, she was likely infertile or abandoned for looking too bizarre, there was no psyop brainwashing to mix in those days. Investing in the wrong mate was the death of your line (still is). The males are more likely fertile (simpler system) but less desirable (both being uncanny valley but the women looking like little girls, there will always be pervs).
“could’ve formed a vital part of survival“
they died before breeding….
you cannot be this stupid….
it’s a black swan against hybrid vigour, which has never been proven
maybe this is why the wages of sin is death, I always wondered about that in context of cultural separation
they must’ve known of such creatures, like tales of giants in the Bible
“The fact that there are different blood types is proof that we are not from the same species”
yes, it proves the modern existence of race, as God willed
“First problem is how they are defining species”
Speciation is why we’re not chimps
also proven in maggots
Genetically differentiated races and speciation-withgene-flow in the sunflower maggot, Strauzia longipennis
who named that?
Discussion of most topics within Evolutionary Biology begins with Darwin. Indeed, On The Origin of Species (1859) continues to influence much of modern Evolutionary Biology. Darwin viewed evolution by natural selection as a very gradual mechanism of change within populations, and postulated that new species could be the product of this very same process, but over even longer periods of time. This eventual process of speciation by natural selection is illustrated by a sketch drawn by Darwin in his personal notebook nearly 20 years before the Origin of Species was published (Figure 1). Here, he proposed a model whereby lineages form from their ancestors by evolving different characters over relatively long periods of time. Darwin indicated that species could form by the evolution of one species splitting into two, or via a population diverging from its extant ancestor to the point it was a new species. [DS: what mixing is attempting, in-group replacement*] Darwin’s insights into evolution were brilliant, especially in light of their being made in the absence of genetics. Indeed, ideas about heredity and the introduction of new genetic material via mutation were to come long after Darwin’s founding theories of evolution.
…Barriers to reproduction.
Under the commonly used ‘Biological Species Concept’ (Mayr 1942), the formation of new species involves the evolution of reproductive barriers to the production of viable offspring either before (pre-zygotic barriers) or soon after (post-zygotic barriers) mating. [no fertilization or later weak implantation] Thus, new species form when individuals from diverging [process, of outbreeding] populations no longer recognize one another as potential mates, or opportunities for mating become limited by differences in habitat use or reproductive schedules. In some cases, these pre-zygotic isolating mechanisms fail to prevent inter-breeding among individuals from separate populations. In these cases, viable hybrids may form, or the consequences of a successful mating attempt may end in failure, either due to the production of inviable zygotes or sterile, non–reproductive offspring. These diverse pre- and post-zygotic barriers are of great importance to speciation biologists because they determine how reproductively-isolated [read: disgusted] populations are from one another, which indicates how far along the often continuous process of speciation that populations are. For example, reproductive isolation [sexual selection/rejection] is weak in the early stages of speciation, but changes to strong or complete [like the visceral subhuman disgust studies, also aversion found in babies] in later stages of speciation (Figure 2). One or more of the many types of isolating mechanisms [freedom of association] may play a role in the evolution of species along a continuum (Figure 2). But how and why might reproductive barriers to genetic exchange evolve?
barriers > not impossibility
“inviable zygotes” bipolar weeb girl, anyone?
so IVF, if we cared about the good of the species, should literally be illegal – I’m sure medical tech helping morons was a plot point in Idiocracy
Nature is telling you No
People are so selfish. Nobody is entitled to reproduce. Ultimately, God set this order into place from a position of higher wisdom. Playing God does not go well – see their medical ailments, rare genetic conditions and mental problems. That could be another reason cave girl was abandoned by both tribes – insanity, they seek out isolated places. Asylums are generally comforting to the insane. The modern world does us a disservice by covering it up, would you really want to breed with certain people if you saw them off-med? Men should be most offended by this because do you wanna find out you mated with crazy once the kids show up? It’s like how ‘women’ don’t disclose they had plastic surgery. You’ll find out eventually. Is that really consent? We need informed consent re heritage and looks as part of marriage law.
Biological success is not having kids. It’s having grandkids. This is also seen in plants.
their own sentence debunks claims of vigour, which would be heritable by ALL descendants, not just one gen:
“F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor that form the basis of the hybrid seed industry.
The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants that have a F1-like phenotype, we have by recurrent [artificial] selection produced pure breeding F5/F6 lines…”
misuse of pure, cutting out the runts by weeding out shows it is not a natural phenomena
The hybrid found in the cave was likely the product of rape, explaining the deadbeating and maternal rejection. Rape is common between races because it over-rides sexual selection…
