Brazil was discovered a cave with cave paintings, giving grounds to believe that the first people in America came to 18 thousand years earlier than believed by many archaeologists.
The new exhibition in Brazil were presented artifacts confirming the existence of the continent’s people for another 30 thousand years ago, whereas it is considered that the first people arrived to America from Asia 12 thousand years ago.

Anthropogeny — the process of origin and evolution of man.
Driving forces of anthropogenesis.
1)anthropoid ancestors pax; 2)most ancient and ancient ancestors pax; 3)people present, morphologic building.
• individual selection aiming to morphophysiological traits is bipedalism, the structure of the brush, the development of the brain; • group selection, aimed at the social organization; • bio-social selection, the result of the combined action of the first two forms of selection. Acted at the level of individual, family, tribe.
The main driving force of anthropogenesis was the work in which you create your tools. The main factor is labour-was specific to the evolution of the pax. Particularly important was the emergence of a straight gait. Biologically bipedalism brought the man a lot of complications. But due to bipedal locomotion freed the hands for tools. At the beginning of the process of formation of the person his hand was underdeveloped. It took a long time for our ancestors moved from the use of the OCD subjects. nature. environment as weapons in their manufacture. Continue reading
Michael Medler from Western Washington University in Bellingham told me that the ancestors of humans could get a chance to develop because they lived near volcanoes and can near them to cook hot food for the brain, reported IA “data” with reference to RIA Novosti.
This thought came to the scientist after he had lived in Hawaii, near the crater of the volcano a few days. The man was sheltering for the night in a tent and cooked outside using volcanic heat that made him think about how distant human ancestors such as Homo erectus (Homo erectus) or some Australopithecus, to be able to live near volcanoes and cook boiled and grilled foods, with no prior intelligence.
To test their hypothesis, the scientist has tested all discovered graves of ancient human ancestors and found that they all lived near volcanoes or hot rift faults that existed in Africa 2-3 million years ago.
One of the main mysteries of anthropology is still how and why the ancestors of the people began to prepare and eat grilled and boiled foods, Continue reading
