For thousands of years, humans have selectively bred dogs to fulfill specific roles, ranging from guarding and hunting to herding and companionship. This deliberate shaping of traits has resulted in ...

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 ...

Among the many misconceptions about evolution—“it’s only a theory”; “it works for the good of the species”—one is that evolution generates biological perfection. If only! In “The Evolution of ...
