The modern human behavior that we a radical leap in technological and cultural complexity muy rápidamente.

‘the modern human behavior that we a radical leap in technological and cultural complexity , which makes our species unique. This includes symbolic behavior, such as abstract and realistic art, and body decoration using threaded shell beads, ocher or tattoo kits, musical instruments, bones, around 90,000 artefacts, stone blades and sophisticated hunting and trapping technology, like bows, boomerangs and nets. Professor Stephen Shennan, UCL Institute of Archaeology, said: ‘Modern humans have been around for at least 160,000 to 200,000 years, but there is no archaeological evidence of any technology beyond basic stone tools until around 90,000 years ago in Europe and western Asia this muy rápidamente . Advanced technology and behavior explodes around 45,000 years ago, when people get there, but not in the eastern and southern Asia and Australia appear until much later, despite a human presence. Saharan Africa, the Sahara, the situation is more complex. Has many of the features of human behavior human behavior – including the first abstract art – are about 90,000 years ago, but found it seem to disappear around 65,000 years before re-emerging some 40,000 years ago.

In the study, the UCL team found that complex skills across generations can be maintained only be learned if there is a critical level of interaction between people. Using computer simulations of social learning, they showed that high and low – skilled groups could coexist over long periods and that the degree of skill they depended on local population density or the degree of migration between them maintained. Unique. Estimates of population in the past, the team went to show that the density was in sub-Saharan Africa, Europe and the Middle East when modern behavior first appeared in each of these regions. The paper also points to evidence that population density would have dropped for climatic reasons at the time when modern human behavior temporarily disappeared in sub-Saharan Africa. Adam Powell, AHRC Centre for the development of cultural diversity, says: Our work proposes a new model for why modern human behavior at different times in different regions of the world, why it disappeared in some places before coming back, and why in all cases, more than 100,000 years after modern humans first appeared.
