The first humans were long-legged and weak-minded
The history of human migration outside of Africa continues to generate interest among anthropologists. In fact, it was the first and most ambitious trip in history, about which still very little is known. So you can imagine the delight of the scientists who discovered in a cave in Georgia, the remains of the first men, appeared outside the Black continent. In addition, the study findings provided interesting information about the life of our distant predecessors.
The source is so important for the science of fossil material became the famous cave of Dmanisi in Georgia. This is a unique place, archaeologists discovered in the early 1990s and were struck by the number of unique finds, hidden in this dungeon. Several years ago, there were found fragments of the skeleton of the genus Homo (our immediate ancestors). Their age, determined by radiocarbon Dating, was equal to 1.77 million years, and this discovery made in the scientific world furor: the fact that these are the earliest finds of this kind outside Africa. Alas, they were very fragmentary and did not allow to reconstruct the shape of the first Asians.
Now as a result of new excavations in Dmanisi were found the well preserved remains of ancient people who lived in the same time period. Their study has brought several important results.First, it has been definitively proved that the first men were direct descendants of Australopithecus – the first hominid became bipedal and started to purposefully use tools. Secondly, it turned out that the anatomy of our ancestors is very peculiar. They had long, well developed legs, virtually no less in this modern people. But the brain was small, from 600 to 775 cubic cm – two times lower than ours.
“Evolution was in the direction of increasing the efficiency of energy use while walking,” says Professor David Lordkipanidze from the Georgian national Museum in Tbilisi. “If you are going on a long trip, you don’t have to be a genius, but it is useful to have strong legs,” – presents the same thought in a slightly different vein, Jeffrey Lightman, head of the research project on the American side.
