Document Summary
Fossil traits: human like = hominin, ape like = ape (not hominin) Dental traits: dental arcade, tooth size/shape, cp3 complex, enamel & cranial crests. Shape of your tooth row (looking at mandibles) For humans/hominins (esp later ones) = later parabolic arch, smaller teeth overall (esp anterior teeth), real reduction in canine (no vampire-like teeth), Apes = u shaped bc of large canines, larger anterior teeth. Early hominins = smaller anterior dentition, but not entirely u-shaped (a mix sometimes) Prognathism: lower part of face sticking out (used to accommodate for teeth: humans have flatter face (less prognathism) Dental formula = i-c-p-m: 2-1-2-3 (modern humans: incisors, canines, premolars, molars. It"s a gap or diastema" (fancy word for gap) in lower jaw that accommodates the larger canine (so these. Located in 3rd premolar (has honing complex, as the canine comes down it actually gets shaprened by the animals can close their jaw easily) premolar [sits by it & sharpens it as well])
