sentences:  The skink has developed setae on its toe pads (or digit pads) for climbing analogous to those of geckos and anoles, but the trait is believed to have evolved independently to these groups, so is an example of convergent evolution.With regards to the trait, other species in the genus, "P. flavipes" and "P. prehensicauda", have the primitive character, and lack the setae.Other skinks within the genus "Lipinia" have also evolved toe pad setae, and within the skink family, four morphologically distinct adhesive microstructures have evolved, possibly all with independent evolutionary origins.
