Promiscuity slows down evolution of new species

Promiscuity mixes up the gene pool and dilutes genetic differences between populations, slowing down the evolution of new species, says new research by an international team led by the University of Bath's Milner Centre for ...

Evolution on the fast lane—One flounder species became two

A research group at the University of Helsinki discovered the fastest event of speciation in any marine vertebrate when studying flounders in an international research collaboration project. This finding has an important ...

Scientists discover when beetles became prolific

Using a previously published and carefully curated 68-gene dataset, the scientists ran a battery of mathematical models to reconstruct the evolution of protein sequences—the results of which, have been published today in ...

Sex: it's a good thing, evolutionarily speaking

(Phys.org) -- Sure, sex may be fun, but it’s a lot of work, and the payoff is by no means certain. Scientists have speculated for a long time on why all living things don’t simply make like amoebas and split.

Ant executions serve a higher purpose, research shows

Natural selection can be an agonizingly long process. Some organisms have a way of taking matters into their own hands, or—in the case of the ant species Cerapachys biroi—mandibles.
