# gst: adhesive performances (sticky approaches): a single type of toe pad (with lots of friction) vs multi functional "drunken stumbles"

AA << shows how different groups of lizards – geckos and anoles – took two completely different evolutionary paths to developing the beneficial trait of sticky toe pads >>

<< anoles seemed to commit to a single type of toe pad, one that generates lots of friction. As a group, they were able to develop sticky toe pads early. Geckos, meanwhile, opted for an evolutionary “drunken stumble,” and seemingly didn’t commit to a single approach, instead evolving toe pads that generate plenty of friction in some species and others that excel at sticking directly to a surface >>
