According to this article. " Neanderthals hunted in groups, which needed a high degree of forward planning, communication, coordination and a good knowledge of the landscape and animal behaviour" and " Neanderthals herded bison, mammoths and even woolly rhinoceroses into sink holes and over cliff faces, a feat requiring all of the intelligent traits listed above"
I guess they were not inferior, but had bad luck? Disease, climate change, limited gene pool, assimilation?
Neanderthals might just have been absorbed into the modern human population. I had my DNA tested by National Geographic and it was almost 6% archaic human. (NG said it was 2.9% Neanderthal and about 3% Denisovan.) This is not abnormal so archaic humans could just have been absorbed into the modern human population.
And if I understand correctly, the National Geographic gene study reveals Neanderthals bread with Homo sapiens.
"Cross-breeding boosted Homo sapiens' ability to cope with cool climates, but the hybrids may have had trouble breeding."
"Homo sapiens and Neanderthals share a common ancestor that probably lived in Africa more than half a million years ago. The ancestors of Neanderthals were the first to move to Europe and Asia while the modern-human lineage stayed in Africa. But after modern humans began to leave Africa less than 100,000 years ago, they interbred with the Neanderthals who had settled on a range stretching from Western Europe to Siberia."
"According to a new DNA study, most humans have a little Neanderthal in them—at least 1 to 4 percent of a person's genetic makeup."
I am guilty in past times of saying "so and so is such a neanderthal." But when I found out about these researchers' findings, I quit saying that.
