Early Humans Bred with Denisovans

Postby Bart Stewart » Fri Mar 16, 2018 7:51 pm

Fascinating article here on a study, some call it a breakthrough, that says humans mated with the Denisovans as well as the Neanderthals. Denisovans are the little-understood bipedal primates that always seem to have the word mysterious tacked onto their name. I recall reading elsewhere about them that they were thought to have been quite rare, as compared to Neanderthals. So it is a little surprising that there was widespread interbreeding with them, which occurred in at least two waves.

Extensive interbreeding happened with the Neanderthals. Huge segments of the population carry Neanderthal genes. What difference it may make in practical terms we don't know. (Or at least I don't know.)

A tweet I saw about this article added more mystery. It said, "A quarter of the chunks of ancient DNA that Browning found in living humans didn’t match either Neanderthal or Denisovan DNA. So, we may have also had children w/other, unidentified hominins.

It seems to me that the better genomic data we have on early human variants, the more we can identify their DNA in modern humans: homo sapiens was obviously not picky in what was deemed {!#%@}.

Changing environment influenced human evolution
By Mary Halton
Science reporter, BBC News

Humans may have developed advanced social behaviours and trade 100,000 years earlier than previously thought.

This is according to a series of papers published today in Science.

The results come from an archaeological site in Kenya's rift valley. "Over one million years of time" is represented at the site, according to Rick Potts from the Smithsonian Institution, who was involved in the studies.

There are also signs of developments in toolmaking technologies.

Environmental change may have been a key influence in this evolution of early Homo sapiens in the region of the Olorgesailie dig site.
