Gilbert and his colleagues are studying a population that may is about to Artspaltung. That is, it splits into two species, that individuals can no longer cross. Plays an important role in the drawing, because it changes because of the enemies.
result, it is possible that potential reproductive partners are not recognized. In captivity, shown in yellow and white copies, that the Yellow prefer each other, while the white matter is. This is a first step that may lead to Artspaltung.
