Human ancestors may soon be “out of Africa” ​​in the evolutionary process or more complex

Beijing, September 3 (Xinhua) An international research team recently reported that they found a number of footprint fossils in Crete, Very early “out of Africa”.

The team, composed of researchers from Poland, Sweden and other countries, reported in the British Journal of Geologists’ Journal that they found footprints fossils unearthed in the west of Crete, sediments and microfossils The analysis shows that they were formed at 5.7 million years ago.

The shape of the human foot is not the same as other terrestrial animals, the soles of the feet are long, the five toes are short and both forward, and no claws. The feet of the apes are more like human hands, and the big toes are long and stretched out to the outside. Researchers believe that the footprints they find are more like humans, especially the shape, size and orientation of the big toes.

The scientific community generally believes that human ancestors were born in Africa savanna, until about 200 million years ago, only the first batch of human resources species moved out of Africa. In the past, the fossils unearthed in Africa show that 4.4 million years ago, the ancestors of the ape began to be more like ape, 3.7 million years ago, the southern Australopithecus footprints closer to humans. Crete found the footprints of fossils than the ape ancestor species is still early for more than 100 million years, but has a clear human characteristics, means that the evolution of human processes than originally thought more complex. Researchers say the Sahara Desert did not exist five years ago, and from the northern part of Africa to the eastern part of the Mediterranean region, the Crete Island was not separated from the Greek continent. At that time the primitive mankind left Africa, through the southeastern Europe, wandering to the area where the Crete is now unimaginable. However, it is still to be seen whether the footsteps can be accepted by the scientific community as a solid evidence of primitive human signs.
