2.Look at the handout on the plesiadapiform Carpolestes simpsoni. Does the hallux (big toe) of Carpolesteshave more symplesiomorphicfeatures shared with the tree shrew, or synapomorphicfeatures shared with the euprimate? List at least one feature you considered.
Station 2: The Eocene – Early Crown Primates (1 pt.)Two extinct superfamilies, Adapoidea and Omomyoidea, group the earliest crown primates. Adapoids are thought to be ancestral to present day strepsirrhines, while omomyoids are most likely ancestral to tarsiers and anthropoids. Many species of adapoids and omomyoids were sympatric(lived in the same place and time) and have been found throughout North America and Europe. Compare the adapoid skull with the lemur and omomyoid skull with the tarsier. Useyour handouts to see more fossil skulls.Lemur: Tarsier: 1.List two traits the adapoidand the lemurshare.
2.List two traits the omomyoidand the tarsiershare.3
