I don't think it had much to do with lack of choices. Try to spend an hour or two in a crowded place in SL using a female avatar and you'll see what I mean.Not discussed in the article is that this might also explain why we have Neanderthal genes in our species. There simply weren't enough of their own kind to afford to be picky about who you slept with.
There are two other theories to explain this. One is that male offspring of a human mother and a neanderthal father always would be infertile.There's no Neanderthal Y chromosome genes in modern humans, indicating that our ancestors thought Neander chicks were hot. Alternately, the larger cross-breed babies weren't viable in human mothers.
In this context, "less compelling" implies there's even an iota of plausibility in this ridiculous theory. This is right up there with faked moon landings and a flat earth. Utter balderdash.Granted, I don't even play a biologist on television, but humans being a bonobo/pig hybrid... It's less compelling to me than...
Which led to scientists discovering that 3rd grade cousins are the awkward prefered choice in humans,...One one hand, we want somebody simialr to ourselves since it increases the chances of producing an offspring but on the other hand we are also atracted to differences since genetic diversity often pays in the long run.
Zoological taxonomy is pretty messed up, and classifications of species keep shifting. They recently reclassified the North African golden jackal as the Golden Wolf, and just like that the whole "some dogs are descended from jackals" narrative became a lot less meaningful.I have some Neanderthal dna. But what I don’t understand, is how two species can produce viable progeny. I thought that, for example, horses and donkeys could produce mules, but mules cant procreate.
i never ever see this explained. Until I do I am just going to assume that Neanderthals were not a separate species from humans.
More on homo erectus.Vaguely on-topic.
Maybe they saw the end coming, built a fleet of spaceships, and escaped to another planet...Did someone already bring up the sustainability issue? One theory is Neanderthals actually had way superior brains and bodies to us.
I'm using the first mention in this thread of Neanderthal Y chromosome's to link to an article I just read, and one reason why it might possibly be hard to find Neanderthal Y chromosome genes in modern humans (because modern humans Y chromosome took over in Neanderthals):There's no Neanderthal Y chromosome genes in modern humans, indicating that our ancestors thought Neander chicks were hot. Alternately, the larger cross-breed babies weren't viable in human mothers. Given that Neander genes are 1.5-2% of non-African populations, there's a lot more of their genes around now than when they were a separate population (thousands to tens of thousands population).
A recent study suggests that those early encounters allowed the Homo sapiens version of the Y chromosome to completely replace the original Neanderthal one sometime between 370,000 and 100,000 years ago.
