Their cognitive development is evident in their symbolic behavior, the professor said. The ostrich egg beads were not only ornaments, but played a major role in bartering with neighboring groups, he said. That practice continues today. The paper claimed that the fossils show that all modern culture came from southern Africa, though the researchers acknowledged it remains difficult to pinpoint where in history that modernity began. Eric Delson, a paleoanthropologist at Lehman College of the City University of New York, said that while the testing used by the researchers to determine the age of the fossils was very clear and reliable, the findings didn't support the idea that all modern human cultures are connected to this find. He said there is evidence that a modern culture already existed in Europe around the time the new find is dated. "They say, 'Modern human behavior first found!'" Delson said. "Well, not exactly." He did, however, applaud the research for finding the origins of one specific group of modern people. Scientists from Britain, France, Italy, Norway, South Africa and the U.S. all took part in the research, helmed out of the University of Witwatersrand in Johannesburg.
