Studies say the "home" of modern human ancestors may be in southern Africa

LONDON, Oct. 28 (Xinhua Zhang Jiawei) A research team published a report in the British journal Nature on the 28th that the "home" of modern human ancestors may be located in a region on the south bank of the Zambeedi River in Africa, the relevant information may help to deepen the academic understanding of the early history of modern humanity.
Australia's Gavin Institute of Medicine and other institutions used timeline, national language and geographic distribution data from more than 1000 mitochondrial genomes of the contemporary southern African population, combined with climate reconstruction data, to conduct an in-depth analysis of the origin of modern human ancestors.Professor Vanessa Hayes, of the Gavin Institute of Medicine and author of the
report, said: "It has been clear for some time that the anatomy of modern
appeared in Africa about 200,000 years ago, but there has long been a long-standing debate in academia about where our ancestors appeared and moved elsewhere.
team's analysis suggests that the "home" of modern human ancestors may be located in the Mazadi Kadi-Okavangogu wetlands. This area of southern Africa is now largely covered by deserts and salt marshes, but there was once a large lake that began to degrade about 200,000 years ago, forming a large wetland.
study showed that modern human ancestors lived in this once-prosperous place for 70,000 years before migrating elsewhere until the climate changed. As humidity increased, green "corridors" emerged in the drier areas around the lake, prompting some of them to migrate first to the north-east, then another to the south-west, and others to remain there.
Hais said: "Those who move south-west appear to be better off than those moving to the north-east and have experienced more stable population growth. ”
