Why some geckos lose their ability to stick to surfaces

8 enero 2015

Biologists have found that evolution can downgrade or entirely remove adaptations a species has previously acquired, giving the species new survival advantages. The researchers focused their attention on geckos, specifically the adhesive system that allows geckos to cling to surfaces. They found that gecko species in which the adhesive system was either lost or simplified saw elevated rates of evolution related to morphology and locomotion.
