A study in the journal Nature tracing the origins of modern human life to Botswana has drawn mixed reviews from experts in the Southern African nation. The study, based on genetics, points to human life emerging around an ancient, massive lake in northern Botswana. But some archaeologists question the study’s findings. The study in the journal Nature is based on genetic findings rather than archaeological evidence, and University of Botswana history professor Fred Morton raises some caution about the conclusion. “To me, the argument is a bit suspicious without some kind of additional evidence to support the genetics,” he said. But while there is caution, local archaeologists such as Phillip Segadika say the report should spur further research of the area.
