The African Origin Theory In Doubt

Scientists have discovered human-like footprints dating back 5.7 million years in the Greek island Crete, which suggests that human ancestors may have existed in Europe at the same time they evolved in Africa.
 
Ever since the discovery of Australopithecus fossils in south and east Africa in mid-20th century, the origin of the human lineage has been thought to lie in Africa. 
More recent fossil discoveries in the same region, such as the 3.7-million-yearold Laetoli footprints from Tanzania, which show human-like feet and upright locomotion, have cemented the idea that hominins originated in Africa and remained isolated there for several million years before.
The discovery of the 5.7 million-year-old humanlike footprints by researchers at Uppsala University , Sweden, overthrows this simple picture.
Human feet have a very distinctive shape that is different from all other land animals'. The combination of a long sole, five short forward-pointing toes without claws, and a hallux (“big toe“) that is larger than the other toes, is unique.
The feet of our closest relatives, the great apes, look more like a human hand with a thumb-like hal lux that sticks out to the side.
“What makes this controversial is the age and location of the prints,“ said Per Ahlberg of Uppsala University .At approximately 5.7 million years, they are younger than the oldest known fossil hominin, Sahelanthropus from Chad, and contemporary with Orrorin from Kenya, but more than a million years older than Ardipithecus ramidus, from Ethiopia, with its ape-like feet. Furthermore, until this year, all fossil hominins older than 1.8 million years came from Africa, leading most researchers to conclude that this was where the group evolved.
Dr El Karim added: "There is huge potential to change our approach to one of the biggest dental challenges we face.
"Our initial research findings in the laboratory suggest that the use of aspirin could offer an immediate innovative solution enabling our teeth to repair themselves." Clinical trials will now be held to test the researchers' findings.
