A central assumption in evolutionary biology is that reproductive isolation accumulates with increasing genetic distance, ‘more likely as a series of small steps than in a single genetic revolution’ ...

Females of iteroparous species may compromise between contrasting reproductive strategies. They should balance the amount of energy devoted to reproduction against the energy saved for growth and ...

Most vertebrates have two sets of chromosomes, one from their mother and one from their father – including humans who are thus diploid. In contrast, polyploidy, meaning to possess three or more sets ...

Although the green toad (Bufo viridis) can today be found all over Central Europe, Asia, Africa, and even on the Balearic Islands, it became extinct in the Iberian Peninsula at the end of the Early ...

Polyploidization, which is expected to trigger major genomic reorganizations, occurs much less commonly in animals than in plants, possibly because of constraints imposed by sex-determination systems.

Most vertebrates have two sets of chromosomes, one from their mother and one from their father - including humans who are thus diploid. In contrast, polyploidy, meaning to possess three or more sets ...
