A team of researchers used revolutionary DNA analysis technology to date some ancient human bones from Asia. According to the study which the journal Science recently published, these bones date from between 70,000 and 120,000 years ago. This means that prehistoric humans left Africa about 60,000 years earlier than previously thought. Thanks to this new research, we now have a new model for the early human migration. It seems that long before the massive migration took place, small groups of humans travelled the world and explored.
According to anthropologist Michael Petraglia, who was part of the research team, before 60,000 years-ago, only small groups of explorers left the African continent. However, even if these groups were quite small, they still left some traces in the modern humans. It seems like those explorers not only set foot on the Asian continent, but they travelled as far as Australia. These people discovered a large portion of the world and even got to know some of our non-human ancestors.
Humans left Africa way before we thought
It’s interesting that this is not the first time evidence has challenged the initial “out of Africa” theory. Just last month, some researchers found striking similarities between the skull of a modern Homo sapien and a 260-million-years old Homo erectus skull. This skull, which was discovered in China, might prove that most of the human evolution didn’t take place in Africa.
Moreover, German archaeologists recently discovered some 9-million-year old teeth which might suggest that humans also originated from somewhere in Europe.
As for this recent study, the scientists think that the true origin of humans will be discovered when we will stop looking at archaeology alone. Different hominin populations had different behaviors and an ecological variation. This is important if we want to discover where we truly come from.
