Humans Evolved by Sharing Technology and Culture

New findings from Blombos Cave show that Stone Age man in Africa exchanged technology to a large extent. The more contact between groups, the stronger technology developed. The exchange of tools can explain humans journey from Africa to Europe. “The pattern we are seeing is that when demographics change, people interact more. For example, we have found similar patterns engraved on…

First Discovery of A Hibernating Primate Outside Madagascar

Hibernation is a state of energy conservation during which body temperature and metabolism are drastically reduced. If this state lasts longer than 24 hours, it is called hibernation. Shorter periods are called daily torpor. There are many mammals that hibernate. However, among primates hibernation is a rare capability, as it had been previously found in three species of lemurs only.…

Why are some wild animals more tolerant to human interaction than others?

When most wild animals first encounter humans, they respond as they would to any predator — by running, swimming or flying away. Over time, some species become more tolerant of humans’ presence, but the extent to which they do is largely driven by the type of environment in which the animals live and by the animal’s body size, according to…

New fossil could reshape our understanding of ape evolution

A fragmented skeleton dug out from a Spanish landfill may force scientists to redraw their theories on the ancestor of humans and all other apes. Pliobates cataloniae, described in the journal Science, reveals that the common ancestor of humans, gorillas and gibbons may have looked more gibbon-like than previously thought. Researchers believe that Old World monkeys and apes split off from…

First DNA Extracted From an Ancient African Skeleton Shows Widespread Mixing with Eurasians

Africa is the birthplace of our species and the source of ancient migrations that spanned the globe. But it has missed out on a revolution in understanding human origins: the study of ancient DNA. Although researchers have managed to sequence the genomes of Neandertals from Europe, prehistoric herders from Asia, and Paleoindians from the Americas, Africa’s hot and humid climate…
