Detailed, neatly-dated palaeoclimate and archaeological records are extreme for working out the impact of environmental change on human evolution. In recent learn, archaeologists from the University of Cape Town and in diversified locations known and described relict tufas — evidence of past flowing streams, waterfalls, and shallow pools — on the place of dwelling of Ga-Mohana Hill within the southern Kalahari, South Africa.

“The final assumption is that the Kalahari is a harsh ambiance no longer moral for early human survival, nonetheless, they did indeed stay there and thrive,” said Dr. Jayne Wilkins, an archaeologist with the Australian Study Centre for Human Evolution at Griffith University and the Human Evolution Study Institute on the University of Cape Town.
“Our learn reveals all over some sessions within the past the barren region used to be lush and hundreds wetter than on the present time. Humans might thrive in these moist prerequisites.”
“We additionally chanced on out that by 20,000 years within the past, folks like been residing within the Kalahari everywhere in the dry prerequisites providing us with an perception into how climate change impacted human evolution.”
Dr. Wilkins and her colleagues studied the tufa deposits, which are springs, waterfalls or ponds which like grew to turn out to be into rock, at Ga-Mohana Hill within the southern Kalahari in South A
