Walking on two feet could have evolved earlier than current estimates, according to analysis of 11.6-million-year-old fossils from a newly discovered great ape species,
Danuvius guggenmosi.The discovery reveals a possible common ancestor of humans and great apes,
write Madelaine Böhme from Eberhard-Karls University in Tübingen, Germany, and colleagues in the journal
Nature.
It also contests theories about how hominin bipedalism evolved, they suggest. "Ever since Darwin, the early evolution of humans and our cousins, the great apes, has been intensely debated," says Böhme.
How humans came to walk on two legs is central to these debates, she adds, and several ideas have been put forward over the past 150 years.
