Fruit - either as the main staple or a supplementary food.
- Most animals are supplementary frugivores.
- Humans are not complete frugivores, not enough nutrients to do that.
- Fruit bats are the biggest of the bats.
- Most of
Final Study Guide
- Bone-Crushing: bones are ground down between flattened teeth; commonly seen in
large extant canids.
- Bone-Cracking: bones are pierced/cracked open by the points of the upper and lower
tooth cusps co
How do we determine who is related to whom?
- Taxon: the name of the taxonomic unit of organization (ex. Species, genus, order)
- Character: a feature that is thought to vary independently from other features: superfi cially unrela

Folivory A Tough Diet
- This type of diet is rough for your teeth and tends to wear away at them.
- Selenodont Teeth - Crescent moon teeth. They can grind and crushing, but have a
little but of a slicing motion too.

North American Savannah
- Warmer climate
- New mountain ranges helped to create these conditions, but when the climate cooled,
the savannah disappeared.
- Volcanic eruptions and ash helped to preserve this lost sava

The Basics and Theories
Question 1 - locomotion
1. Plantigrade - form of locomotion in which the organism walks by planting its whole
foot down (with podials and metatarsals flat)
2. Digitigrade - the organism walks on the dig
Relatively Long legs increase length of stride
Speed = rate of stride * length of stride
Increases angular velocity
Role of Muscle Attachments
- Muscles pull on bones and cause the movement of those bones
