A small team of evolutionary biologists from the University of Kansas, the American Museum of Natural History, and the University of Helsinki, has found that a family of snakes known as Elapidae originated in Asia, not Africa, ...
Hosts and their parasites are in constant competition. Through genetic diversity, the host can change in such a way that infection is no longer possible. However, the parasite adapts quickly—and the game starts all over ...
