As conceived by Charles Darwin in the 1800s, evolution is a slow, gradual process during which species adaptations are inherited incrementally over generations. However, today biologists can see how ...

Using genomics, evolutionary biologists test several hypotheses on the origin of viruses. New evidence suggests they may have emerged more times than previously thought. Corroborating the virus-first ...

In the world of emerging infectious diseases, one of the looming threats comes from the so-called zoonotic diseases—pathogens that somehow make the jump from an animal host to a human one. This ...
