> Neanderthals from 400kya are often classed as Heidelbergensis.
replyHeidelbergensis is the last common anscestor of Neanderthals, Denisovans and us.
We were all around for just as long, 400kya+, and before that, it was Homo Erectus.
All of them, Erectus, Heidelbergensis, Neanderthals, Denisovans and Sapiens were walking around at the same time. There's plenty of fossil records we've uncovered that show that to be true.
It was only in the last 100k years or so that we remained and the other variants "died out".
Did they really die out, or did the population just merge with modern humans? Most people on the planet have some Neanderthal DNA, so clearly there was some intermixing. If modern humans were a much larger population, it makes sense that the Neanderthals only contributed a small amount of DNA to the gene pool. I could imagine that they were just slowly absorbed into the much larger Sapiens population.
