Evolutionary Biology: Why Cattle Only Have two Toes

ongulateDuring evolutionary diversification of vertebrate limbs, the number of toes in even-toed ungulates was reduced and transformed into paired hooves. Scientists at the University of Basel have identified a gene regulatory switch that was key to evolutionary adaption of limbs in ungulates. Denis Duboule’s team has contributed to this study, published in Nature on June 19, 2014.
