The first representatives of our genus did not put a lot of effort in the manufacture of tools. The scientific staff of the Australian National University in Canberra said that the erectus people were the first representatives of our race, lost the competition to their offspring because of “laziness” – the inability to produce complex tools.

The first representatives of our genus did not put a lot of effort in the manufacture of tools. This conclusion was made on the basis of studying of materials of excavation on one of the sites of Homo erectus in Saudi Arabia, where lived the first people to leave Africa.
“They made tools from the first stones, which they found at their sites, which is not similar to the more ancient Homo, purposefully seeking high-quality raw materials for their instruments,” – said one of the experts at the Australian National University in Canberra.
“Not like that these people are too annoying for any reason. They made tools from the first stones, which they found at their sites, which is not similar to the more ancient Homo, purposefully seeking high-quality raw materials for their instruments,” says CERI Shipton (Ceri Shipton).
It turned out that our ancestors used heavier for processing stones to make tools, despite the fact that a short distance was a mountain with easier material. But instead they took the one that was closer to the settlement. These stones usually washed by the rivers from the mountains to the plains where people lived.
Thus, the closer the village was to the water, the larger were the instruments of labor, and Vice versa. This gave scientists the idea that bipedal people do not particularly spend time and effort in search of materials, their processing and manufacturing of certain items.
Their laziness and conservatism, apparently, caused the extinction of this group of Homo erectus in the time when Arabia began to turn into a desert, – quotes the opinion of the anthropologist CERI Shipton the journal PLoS One.
