In this Science Minute from NIMBioS, Dr. Sandy Kawano, NIMBioS postdoctoral fellow, explains how forelimbs and hind limbs evolved to support more weight so that tetrapods could move from water to the land. Her new study published in the Journal of Experimental Biology investigates the stresses experienced by the limb bones of tiger salamanders during terrestrial locomotion.
