Basel geneticist David Thaler discovered that virtually 90 percent of all animals on Earth appeared at right around the same time.
More specifically, they found out that 9 out of 10 animal species on the planet came to being at the same time as humans did some 100,000 to 200,000 years ago.
"This conclusion is very surprising," says Thaler, "and I fought against it as hard as I could."
Over the last decade, hundreds of scientists collected around 5 million DNA barcodes from 100,000 animal species in different parts of the globe. Stoeckle and Thaler looked through these 5 million genetic imprints to find one of the most surprising discoveries about evolution to date.
There are two types [...]
