The Ugly Little Boy
Way back before the internets, Isaac Asimov wrote, The Ugly Little Boy, which he included in his anthology Nine Tomorrows. Robert Silverberg later expanded the short story into a novel, which I have not read. In 1977, Barry Morse and Kate Reid starred in a TV version, which is supposed to be very faithful to the short story and is available on youtube.
The boy was a neanderthal (or neandertal) child, brought to, and kept in, the future at great expense of energy by a corporation for scientific research. In the years after the story was written, I read that one scientist claimed we probably couldn’t tell a well-dressed neanderthal apart from anyone else on the street, but knew that when the lay person heard, “neanderthal” they saw a dim but muscular caveman with a sloping forehead. And that is how most popular culture has portrayed them, one example being Jean M Auel’s Clan of the Cave Bear books and the 1986 film starring tall, pale, blonde Darryl Hannah as a Cro-Magnon, adopted by a tribe of stocky, swarthy (but not black-skinned), black-haired Neanderthals.
But if one were to recast Clan of the Cave Bear based on the latest information, one should cast light-skinned people as the Neanderthals, and a taller, darker-skinned woman (perhaps Rosario Dawson) as Ayla the Homo Sapiens Sapiens or Early European Modern Human (EEMH). It is now suggested that populations of Homo Neanderthalensis had already adapted to Northern climates over some three or four hundred thousand years, and that the still dark-skinned Homo Sapiens benefited by acquiring those traits through interbreeding as they displaced the older species. [It is also counter-suggested that the neanderthal DNA remains from before the two species diverged from Homo Erectus.]
It is currently thought that humans (except those strictly descended from sub-Saharan Africans) have between 1% to 4% of neanderthal DNA and that some Melanesians and Australian Aborigines have Denisovan DNA as well. In other words, most of us humans are actually ugly little boys and girls, too.
