Researcher shows dove species can interbreed

Doves that have ‘affairs’ with different species of dove don’t have to worry about their posterity. Dutch Biologiest Paula den Hartog showed that descendants of two different species of dove had no special health issues and were able to reproduce. Den Hartog presented her research last Thursday at the University of Leiden.

Descendants of two different animal species are frequently infertile or they die while an embryo. Examples of this are the mule, a cross between a horse and a donkey, which is infertile; offspring between goats and sheep usually die before birth.

Den Hartog discovered that offspring from two different species of dove have a different call than either parent species. Because of their exotic voice they attract mates and are able to reproduce.
