Early humans may have wiped out many turtles millions of years ago

Early hominins may have been wiping out other species long before destruction-causing modern humans evolved, according to changes in the fossil record. About 5 million years ago, land-living turtle species, including tortoises, started going extinct at a much higher rate than they had been, suggests a new analysis.

“Our finding… highlights how far back in time a negative hominin influence on biodiversity extends,” write Anieli Pereira, formerly at the University of Gothenburg in Sweden, and her colleagues.
