For some reason, I forgot to time-stamp things today. The lectures were still recorded, but I won’t be able to correlate information appropriately.


Primate Classification
Ancestral Traits: No post-orbital bar, five digits, divergent orbits, small brains, strepsi rhini (wet nose) (split lip), large snout (big, forward nose), tapetum lucidum (Reflectivity of the retina), multiple nipple pairs, bicornuate uterus, unfused madibular symphysis

Derived Traits: Grasping hand and divergent hallux, nail on hallux, post orbital bar, brain complexity, petrosal bulla, reduced snout, reduced olfaction complexity, convergent orbits

Strepsirhines have tooth comb, wet nose, tapetum lucidum. Haplorhines do not.
Prosimians have unfused mandibular symphysis, bicornuate uterus, multiple nipple pairs.
Anthropoids have fused madibular symphysis, fused post orbital bar
Platyrrhines have laterally facing nostrils, dental formula.
Catarrhines have downward-facing nostrils, dental formula, ischial callosities
Cercopithecoid have bilophodont molars
Homonoids have larger brains, no tails, long arms, broad thorax

Review module that will be posted on canvas.
