The propagation of admixture-derived evolutionary potential

Adaptive radiation—the rapid evolution of many new species from a single ancestor—is a major focus in evolutionary biology. Adaptive radiations often show remarkable repeatability where lineages have undergone multiple ...

Shifts in butterfly mating preferences

In their efforts to identify the genetic basis for differences in mate choice that keep two co-existing species of butterfly separate, evolutionary biologists at LMU have identified five candidate genes that are associated ...

Human genetics: A look in the mirror

Who are we? Where did we come from? How did we get here? Throughout the ages, humans have sought answers to these questions, pursuing wisdom through religion, philosophy, and eventually science. Evolutionary analyses published ...

Lungfish fins reveal how limbs evolved

The evolution of limbs with functional digits from fish fins happened approximately 400 million years ago in the Devonian. This morphological transition allowed vertebrates to leave the water to conquer land and gave rise ...

Researchers track origin of one of nature's biggest killers

A mosquito species that is one of the world's leading killers of humans arose more than 7 million years ago on islands in the Indian Ocean, some of which had no mammals of any kind, according to a genetic analysis by Yale ...
