Genetic exchange discovered in anciently asexual rotifers

Evolutionary biologists at Skoltech have discovered recombination in bdelloid rotifers, microscopic freshwater invertebrates characterized by their presumed ancient asexuality. The existence of such anciently asexual groups ...

Giant lizards learnt to fly over millions of years

Pterodactyls and other related winged reptiles that lived alongside the dinosaurs steadily improved their ability to fly to become the deadly masters of the sky over the course of millions of years.

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 ...

Lefties and righties: Asymmetry in fish genitalia

Evolutionary biologists from the University of Konstanz have resolved a century-old question regarding the asymmetric genitals of internally fertilizing fishes of the family Anablepidae. Surprisingly, the direction of genital ...
