Mosaic evolution

Abstract

Today we will be examining some morphological features in skulls from several species of hominoids (apes and humans). Each group will be examining changes in one feature, and will present their findings to the rest of the class. Once your group is assigned a feature to examine, use the description below to measure the important characters on each of the skulls. Record these on the data sheet. You will then use these data to examine the evolution of your feature with the help of the hominoid phylogeny included in this handout. You might also note relevant information regarding the environment or other biology of the species whose skulls you are examining. HANDLE THE SKULLS WITH EXTREME CARE – THEY ARE VERY DELICATE.!
