Ancient footprints in Crete challenge theory of human evolution – but what actually made them?
The oldest known human footprints, from Africa, are by Australopithecus Matheusvieeira Researchers have discovered some 50 footprints at Trachilos in Crete that are nearly six million years old. It looks like they may be from a hominin – a member of the human species after separation from the chimpanzee lineage. But, as the authors point out themselves, the findings are highly controversial – suggesting human ancestors may have existed in Crete at the same time as they evolved in Africa. So what should we make of it all? If the footprints are confirmed to be from a hominin – additional studies are needed before we can know for sure – it is unquestionably exciting. The oldest footprints confirmed as hominin are the Laetoli series, which date to 3.65 million years. The Laetoli series, found in Laetoli, Tanzania, are now known to have been made by the early human ancestor Australopithecus. It was up to six feet tall and had a foot ...
