HumanKind’s ancestral’ homeland pin pointed in Botswana.
A large ancient wetlands region spaning northern Botswana. Once teerming with life but now dominated by desrt and salt flats-may represent the ancestral home land of all of the 7.7 billion people on Earth today researchers said.
Their study guided by maternal DNA, data form than 1,200 people indigenous to southern Africa., proposed a Central role for this region in the early history of humankind starting 200,000years ago., nurturing our species for 70,000years before climate changes paved the way for the first migrations.
A lake that at the time was Africa’s largest twice the area of today’s Lake lake Victoria gave rise to the ancient wet
Covering the Greater Zambezi river basin that includes northern Botswana into Namibia to the west and Zimbabwe to the east, the research ers said
It has been long established that Homo Sapiens Originated somewhere
In Africa before spreading world wide.
“But what we hadn’t known until this study was where exactly this homeland was ”
Said genercitist Vanessa Hays of the Garan Institute of Medical Research and University of Sydney, who led the study published in the Journal Nature.
The oldest known Homo sapiens fossil evidence date back more than 300,000years from. Morocco. The new study suggests that early members of our species is represented by the Morocco remains may nor have left any ancestors living today.
“There is no contradiction between the presence of an early Homo Sapians like skull in northerners Africa, which may be form an exciner lineages and the proposed southern African origin of the Homo.
Sapians lineages that are still alive.”added study co author And Timmerman a climate physics at Pusan National University in South Korea.
The ancient lake Makgadikgudi began to break up about 200,000 year ago giving rise to a sprawling wetland region inherited by human hunter gatherers.
“It can be viewed as a massive extension of today’s Okavango Delta werland area,”Timmermann said.
Changes in Earth ‘s axis and orbit caused climate. rainfall and vegetation shifts that set the stage for early migration of this ancestral group of people away form the homeland region, first toward the northeast 130,000 years age, then towrard the Southwest 110,000 years ago, Timmerman added.
The study provides the first quantititative and well -dated evidence that astronomical driven climate changes in the past caused major human migration events. Which then led to the development of genetic diversity and eventually cultural ethnic and linguistic identity..
