Genes from the father facilitate the formation of new species

The two closely related bird species, the collared flycatcher and the pied flycatcher, can reproduce with each other, but the females are more strongly attracted to a male of their own species. This has been shown by an international research team directed by Anna Qvarnstrm at Uppsala University ...

How the plant immune system can drive the formation of new species

Plant geneticists know that not all plants from the same species can be successfully bred. Apparently, there are reproductive barriers that not only prevent the exchange of genes between well-established species (which goes to the very definition of a species), but also between varieties of one an...

Early initiation of Arctic sea-ice formation
