Tsukuba, Japan—Cooperation is fundamental to human societies. Building on the hypothesis that heightened environmental variability in Africa during the Middle Stone Age influenced behavioral evolution ...

In a recent review published in the journal Nature Reviews Earth & Environment, researchers discussed the role of climatic shifts and vegetation changes in driving the evolution within the subfamily ...

Researchers found that ancient hominids—including early humans—were exposed to lead throughout childhood, leaving chemical traces in fossil teeth. Experiments suggest this exposure may have driven ...

Researchers have demonstrated that intensified environmental variability (EV) can promote the evolution of cooperation through simulation based on evolutionary game theory. This result offers a new ...
