(Ch.10) Flashcards
What are the five primary primate traits?
- Convuluted Brain
- Grasping Ability
- Binocular Vision
- Flexible Limbs
- Sociability
What are the six primate groups?
- Strepsirrhines/Haplorrhine
- Tarsiiformes
- New World Monkeys
- Old World Monkeys
- Apes
- Hominins
What two primates are Strepsirrhines?
- Lemurs
- Lorises
What are four characteristics of the Strepsirrhine Group?
- Unfused Mandible
- No postorbital closure
- Wet nose
- Toothcomb
(they look a little more dog-like)
The Suborder Haplorrhine encapsulates three subgroups. What are they?
- Tarsiers
- Old-World Monkeys
- New-World Monkeys, Apes, Humans
New World Monkeys are also known as…
The Platyrrhini Group.
Old World Monkeys are also known as…
The Catarrhini Group.
What are Tarsiiformes?
(think mort from the island of Madagascar)
These are technically Haplorrhines but are very similar to Strepsirrhine in traits. They are vertical clingers and leapers with pointy molars and nocturnal habits.
Describe the Platyrrhini Group.
(Think New World monkeys in trees)
Platyrrhini have the dental formula 2.1.3.3, and some have prehensile tails. They have side-directed nostrils as well.
The Catarrhini group actually encapsulates three smaller groups as well; what are they?
- Old-World Monkeys
- Apes
- Hominins
Describe the Catarrhini Group.
(These are our most recent ancestors)
Catarrhini have a 2.1.2.3 dental formula and downward-facing nostrils.
What are the characteristics of Old World Monkeys?
(These are a subcategory of the Catarrhini Group- think, bigger, and buffer monkey)
Old World Monkeys have bilophodont molars and nonprehensile tails.
What are the characteristics of Apes/Humans?
(These are a subcategory of the Catarrhini Group)
We have the Y-5 molars, no tail, and a very large brain.
