As a layperson I find these Neanderthal DNA numbers to be rather confusing. I'm confident the following is wrong somehow, and I'd love to hear why: I've read numerous times that the average European's DNA is ~2% Neanderthal, but I've also read that the difference between the human genome and the chimp genome is only 1-4%. So, that ~4% of DNA is 'human DNA', while the rest is basically hominid boilerplate. Neanderthals were presumably similar--~95% boilerplate hominid DNA and 5% 'Neanderthal DNA'. So, if only 4% of my DNA is 'Human DNA', and 2% of that is 'Neanderthal DNA'... wouldn't that make me half human, half Neanderthal? (i.e. 96% boilerplate, 2% human, 2% Neanderthal). My assumption here is that the 5% 'human DNA' and the 5% 'Neanderthal DNA' overlap, and so any 'Neanderthal DNA' in my genome replaced 'human DNA' as opposed to boilerplate DNA, which might be wrong, but even with zero overlap, wouldn't that make me at least one third Neanderthal, two-thirds human? (i.e. 94% boilerplate, 4% human, 2% Neanderthal)
