Popular Science: Testosterone does not make big fighters – at least in chameleons?

While body size is one of the biggest differences between sexes (i.e. sexual dimorphism) in chameleons, little is still known about the mechanism of its evolution. Scientists assumed that male sex hormones play a major role in the ontogeny, as it is thought to be in most vertebrates. However, a study done in geckos suggested otherwise. Three scientists from the Department of Ecology of Charles University’s Faculty of Science led by prof. Lukáš Kratochvíl have carried out a study in chameleons to find out how male gonadal androgens impact the ontogeny of sexual dimorphism.
