A new study suggests that the origin of humans has not started from a particular region in Africa. The study says that humans can come from various parts of the continent
Africa Is Home
A team of researchers from the University of Oxford and the Max Planck Institute for The science of human history challenges the previous concept that human life began from a single population in Africa. The team believes that human ancestors were both physically and culturally different over 300,000 years ago. The researchers, led by Eleanor Scerri, an archaeologist, have combined a plethora of different approaches to examine how modern humans evolved thousands of years ago.
Scientists discovered that not only homo sapiens came from different parts of Africa. species, but these particular populations were separated due to various physical barriers, including deserts and forests, which led to diversification.
Over time, these environments began to change creating migrations that made homo sapiens contact possible. Scientists believe that people could have gone through several cycles of cultural and genetic mixing before becoming isolated again. The researchers say that this new theory on human evolution helps to better explain the genetic, fossil and archaeological evidence left behind.
Humans were diverse since the beginning
Scientists continue that this new hypothesis may explain why the bones of 300,000 years ago "In the fossil record, we see a tendency to mosaic, to the continental scale, towards the modern human form, and the fact that these Scerri continued:
Scerri continued that certain artifacts, such as stones and tools, have grouped distributions over time and that , although there is a worldwide trend towards a more clbadified material culture, it does not appear to come from one region.
Mark Thomas, a University geneticist College London and co-a According to the author of the study, it is difficult to connect the DNA found in today's Africans to the DNA found in the bones of the ancestors who lived there for the past 10,000 years, and added that the researchers found indications of reduced connectivity of the past, ancient lineages and varying levels of diversity that a single population would struggle to control.
The study was published in the journal, Trends in Ecology & Evolution.
