Learned taxidermy from his neighbor John Edmonstone, who told him
about rainforests
• Joined a natural history group on campus
• Studied marine invertebrates
• Studied plant classification at the University Museum

, Today we understand that these discrete units of heredity (genes) are found
in specific locations (loci) on chromosomes, and that humans have 23 pairs
of chromosomes.
Ape Traits
Give this one a try later!
• BOTH old world monkeys and apes have a 2:1:2:3 dental formula
• Apes have a Y pattern to their five cusps (Y-5 pattern)
• Monkeys are bilophodont or have two major ridges formed by four cusps
- Apes (tend to) have big, sexually dimorphic canines
• Have fully closed eye orbits
• Enhanced color vision
• Larger body size
• Larger brain size (relative to body size)
• Greater social complexity
Absolute Dating: Radiocarbon Dating

a chemical analysis used to determine the age of organic materials based
on their content of the radiocarbon 14c
Carbon - the fourth most common element in the universe by mass.
• Radiocarbon can ONLY be used to date fossils less than ~60,000 years
old.

• ~35 mya, oldest clear anthropoids
• Strepsirhine-like molars
• 2.1.2.3 dental pattern like Catarrhines
• Frugivores or folivores
• Quadrupedal locomotion

is one of several ways that a trait, disorder, or disease can be passed down
through families.

•Shock absorbers
•Enlarged heel pad

The first true primates from the Eocene
Relative Dating: Cultural Dating

• Uses material culture - typically stone tools to give relative dates to an
archaeological site or a fossil
niche separation

niche= is a particular set of resources and roles in an
ecosystem.
• Robust species co-exist with gracile species and even early Homo before
going extinct.
• Different morphology between robust and gracile Australopiths living at
the same time suggests they were occupying different niches.
