Homo sapiens were not the only kind of humans to reside on this planet. Two experts in the field exposed to the Voice of Russia that other forms of humans died out due to poor social networking and climate. Interbreeding between
Homo sapiens and Neanderthals went on hundreds and thousands of years ago, making modern humans around one percent Neanderthal according to the newest book on evolution,
Lone Survivors."There is no single center where we originated even within Africa, our origins were kind of composite, a patchwork, Professor Chris Stringer, author of
Lone Survivors and Researcher at the Natural History Museum in London said and added, "So different bits of Africa contributed to what we call today modern humans."
The new theory on how present day humans came to be, according to the book
Lone Survivors, is that we came from Africa and then journeyed from there. However, we are not full bred modern humans, as we all have a microscopic percentage of Neanderthal DNA in us, if originally from Europe.
Though, Australians and New Guineans have an extra ingredient in their DNA, from an archaic human known as the Denisovans. This group was discovered in a cave in Siberia, and those with the Denisovan gene, also have Neanderthal and modern human roots tied to them.
It was more than likely that interbreeding made it possible for certain humans, who were not used to the environment, to have offspring that would survive through disease and other possible debilitating factors of the region.
