We examined causes of speciation in asexual populations in both sympatry and parapatry, providing an alternative explanation for the speciation patterns reported by Dieckmann and Doebeli (1999) and ...

Models of adaptive speciation are typically concerned with demonstrating that it is possible for ecologically driven disruptive selection to lead to the evolution of assortative mating and hence ...

It’s not every day that you get to see evolution happen before your eyes. Scratch that, until very recently, it wasn’t any day, since the process of speciation — in which one species splits into two ...

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 ...

It's hard to mate with something you can't see, at least for certain African fish. That's the key message of a paper that appears in today's issue of Nature. This may seem like an obvious statement, ...

Darwin suggested that the action of natural selection can produce new species, but 150 years after the publication of his famous book, 'On the Origin of Species', debate still continues on the ...

BATON ROUGE – In a study that sheds light on the origin of bird species in the biologically rich rainforests of South America, LSU Museum of Natural Science Director and Roy Paul Daniels Professor in ...

An attractive scent is just as important as good looks when it comes to choosing a mate -- at least among stick insect populations. An attractive scent is just as important as good looks when it comes ...
