Is it even possible? Yes, it is.

Scientists examining the genomes of West Africans have detected signs that a mysterious extinct human species interbred with our own species tens of thousands of years ago in Africa, the latest evidence of humankind's complicated genetic ancestry.
The study indicated that present-day West Africans trace a substantial proportion, some 2% to 19%, of their genetic ancestry to an extinct human species – what the researchers called a "ghost population."
"We estimate interbreeding occurred approximately 43,000 years ago, with large intervals of uncertainty," said University of California, Los Angeles (UCLA) human genetics and computer science professor Sriram Sankararaman, who led the study published this week in the journal Science Advances...
Previous genetic research showed that our species interbred with both the Neanderthals and Denisovans, with modern human populations outside of Africa still carrying DNA from both. But while there is an ample fossil record of the Neanderthals and a few fossils of Denisovans, the newly identified "ghost population" is more enigmatic...
Sankararaman said this extinct species seems to have diverged roughly 650,000 years ago from the evolutionary line that led to Homo sapiens, before the evolutionary split between the lineages that led to our species and to the Neanderthals.
The researchers examined genomic data from hundreds of West Africans including the Yoruba people of Nigeria and Benin and the Mende people of Sierra Leone, and then compared that with Neanderthal and Denisovan genomes. They found DNA segments in the West Africans that could best be explained by ancestral interbreeding with an unknown member of the human family tree that led to what is called genetic "introgression."

Looks like mostly nuclear DNA; the estimate of 650,000 years as well.
LOL!!!
Plus, Thailand is not in Africa. Nice lookin’ art though...
Very few people know that Sunken Civ is a YUUUGE fan of Georgio and the Ancient Aliens theories. You have kept that hidden so well
I'm also a yuuuge fan of PT Barnum, and for the same reason. :^) I'm reminded of something said by a friend of my bestie -- that he subscribed to Weekly World News because it was the only paper you could trust. :^D
BAT BOY LIVES!
He's generally hangin' around somewhere. /rimshot
And not even a picture from the right continent. Talk about irrelevant!
Y’all need to read some Sitchen. He explain it all.
I am pretty sure they were “together”. Not so sure of the marriage part.
Heh - I had to look back. I think I was referring to the “...breeding...with large intervals of uncertainty...” and making a marriage joke.
Perhaps in my best Rodney Dangerfield voice.
