The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

Butterfly wing patterns are attractive, not just to artists, writers and naturalists, but also to other butterflies. In fact, they play an important role in signalling between potential butterfly ...

This is a preview. Log in through your library . Abstract Among the most debated subjects in speciation is the question of its mode. Although allopatric (geographical) speciation is assumed the null ...

The European whitefish (Coregonus lavaretus) species complex is a classic example of recent adaptive radiation. Here, we examine a whitefish population introduced to northern Finnish Lake Tsahkal in ...

It's a bit like a character in a movie going off and having adventures that change him so drastically that when he returns, the folks in his hometown no longer recognize the way he looks and behaves.

Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all ...

How do new species form? Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate. Here, we review both ...

The offspring of crosses between related species can sometimes fill a new environmental niche, and such hybridizations may even lead to speciation. In the 20th century, animals such as mules and ...

A genetic study of island lizards shows that even those that have been geographically isolated for many millions of years have not evolved into separate species as predicted by conventional ...

Male pregnancy in seahorses may do more than reverse traditional gender roles. It could also influence the way new species form from single populations of these ancient creatures. Studies have shown ...

German researcher Christian Rabeling was digging up ant colonies on a college campus in Brazil when he found something unexpected—certain ants appeared smaller and shinier and had wings. Rabeling soon ...
