New Evolutionary Theory Suggests Distinct Human Species Coexisted

Friday, December 21, 2012

As recently as 1970, some evolutionary scientists believed there was no single point of origin for modern humans. Instead, they believed, we evolved globally all over the world. That view, known as multi-regionalism, suggests that human evolution took place seamlessly from Homo erectus to modern humans.

In the last four decades, however, many new evolutionary theories have been created and revised. The "Out of Africa" theory, for example, maintains that humans emerged rapidly in one small part of Africa and then spread to replace all other humans within and outside the continent.

Chris Stringer has a theory of his own. He is a researcher at the Natural History Museum in London and author of  "Lone Survivors: How We Came to be The Only Humans on Earth." The book suggests that distinct humans coexisted and competed across the African continent, exchanging genes, tools and behavioral strategies.

I recall reading that the oldest musical instrument found so far is a flute made by a Neanderthal craftsperson. 80,000 years old, I think it was. Perhaps some of our interest in music came from the Neanderthals. Our version of humanity seems to be pretty good in particular at killing, which has served us well, in a sense, kinda, sorta. But perhaps we will have to modify/manage that in order to survive further.

If the Ancient Mayans were walking around New York today, they would have been high fiving each other in their correct assumption that the end of the world happened
