Archaeologists discovered a 50,000-year-old social network in Africa
The scientists at the Max Planck Institute for Evolutionary Anthropology in Germany have presented evidence of a social network in East and South Africa. Archaeologists have discovered a 3,000 kilometers long chain of beads on the territory of these regions. This information was published in The Jerusalem Post.
According to the researchers, the age of the social network is more than 50 thousand years. To communicate, Homo sapiens resorted to beads that were made from ostrich egg shells.
German specialists Jennifer Miller and Yiming Wang suggested that the subject they were studying referred to a constituent element of the social network.
"In all the 50,000 years we've studied, this is the only period when the characteristics of the beads are the same," one of the scientists noted.
In a new research project, experts compared the features of ostrich egg shell beads to the changes in the regional climate. As a result of the study, they found that the divergence of people coincided with the time when southern and eastern Africa recorded an increase in rainfall.
