But these are not another species. These are modern humans. Genetically, anatomically and such the same as we are.
Can you provide a link to studies done?
I did a quick search:
Oldest Homo sapiens bones ever found shake foundations of the human story
In
the first of two papers published in Nature on Wednesday, the researchers describe how they compared the freshly-excavated fossils with those of modern humans, Neanderthals and ancient human relatives that lived up to 1.8m years ago. Facially, the closest match was with modern humans. The lower jaw was similar to modern
Homo sapiens too, but much larger. The most striking difference was the shape of the braincase which was more elongated than that of humans today. It suggests, said Hublin, that the modern brain evolved in
Homo sapiens and was not inherited from a predecessor.
Apart from being more stout and muscular, the adults at Jebel Irhoud looked similar to people alive today. “
The face of the specimen we found is the face of someone you could meet on the tube in London,” Hublin said. In a
second paper, the scientists lay out how they dated the stone tools to between 280,000 and 350,000 years, and a lone tooth to 290,000 years old.
That sounds incredible, then further on we read,
Shea was also uneasy with the scientists combining fossils from different individuals, and comparing reconstructions of complete skulls from fragmentary remains. “Such ‘chimeras’ can look very different from the individuals on which they are based,” he said.
“
For me, claiming these remains are Homo sapiens stretches the meaning of that term a bit,” Shea added. “These humans who lived between 50,000-300,000 years ago are a morphologically diverse bunch. Whenever we find more than a couple of them from the same deposits, such as at Omo Kibish and Herto in Ethiopia or Skhul and Qafzeh in Israel, their morphology is all over the place both within and between samples.”
Interesting area of discovery none the less.
