Genes from the father facilitate the formation of new species
Date:10/5/2007

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 in todays Net edition of Science. They demonstrate that the gene for this sexual preference is found on the sex chromosome that is inherited from the father and that only females have a copy of. The discovery sheds new light on how new species are formed.

The formation of new species takes millions of years. It often happens when a population (group of individuals) is divided and separated geographically and then adapts to disparate environments over thousands of generations. For instance, the earths ice ages have led to many such population splits. But divided populations often come into contact with each other before they have had time to become entirely sexually isolated from each other. When individuals mate with each other from such split populations that have not quite become separate species, their offspring (so-called hybrids) often have limited viability.

Anna Qvarnstrms research team from Uppsala University in Sweden, working with scientists from Norway, the Czech Republic, the US, and Holland, have studied natural hybridization between two closely related bird species, the collared flycatcher and the pied flycatcher. The two flycatcher species (or quasi species) have come into contact with each other after having been separated during the last ice age. The question they addressed was whether the flycatchers will conclude the species formation that is under way and become entirely sexually isolated from each other or, instead, if they will meld into the same species again.

We found that females in the hybrid zone develop a sexual preference for males belonging to their own species and that this preference is determined by ge
