How early humans evolved by sharing technology, culture
Our early ancestors managed to evolve and journey across the earth by exchanging and improving their technology, researchers say after analysing Blombos Cave in South Africa. The team looked closely at spear points made of stone as well as decorated ostrich eggshells to determine whether there was an overlap and contact across groups of Middle Stone Age humans.
London: Our early ancestors managed to evolve and journey across the earth by exchanging and improving their technology, researchers say after analysing Blombos Cave in South Africa. The team looked closely at spear points made of stone as well as decorated ostrich eggshells to determine whether there was an overlap and contact across groups of Middle Stone Age humans.
“We are looking mainly at the part of South Africa where Blombos Cave is situated. We sought to find out how groups moved across the landscape and how they interacted," said Christopher S Henshilwood, professor at University of Bergen.
The pattern they noticed is that when demographics change, people interact more. “For example, we have found similar patterns engraved on ostrich eggshells in different sites. This shows that people were probably sharing symbolic material culture, at certain times but not at others,” added Dr Karen van Niekerk, a UiB researcher and co-author.
This sharing of symbolic material culture and technology also tells more about Homo sapiens' journey from Africa to Arabia and Europe. Contact between cultures has been vital to the survival and development of our common ancestors Homo sapiens. The more contact the groups had, the stronger their technology and culture became.
