Neanderthals are like "squatty eskimos" who are "100% human"? Are you for real?
They have sequenced Neanderthal DNA from bone samples and it is not h. sapiens sapiens. Neanderthal mitochondrial DNA differs by 202 base pairs compared to modern humans.
That's chemistry, not conjecture.
(Also, the word is Inuit, not "Eskimo" and they are by no means "squatty" you ignoramus. Their traditional clothing is bulky to keep warm but I've worked with and gone to school with Inuits and they're just regular people, as proportioned as you and me. I mean seriously, you sound like you're from the 19th century.)
