(humans)
- Family: Hominidae

Prosimian characteristics
- Most are nocturnal
- insect import in diet
- Tend to be smaller than other primates
- Tend to be solitary
- Greater reliance on olfaction
- Moist rhinarium
- Vision less develped
- Faster maturation rates
- More specialized dentition
- Vertical-Clinging and leaping mode of locomation
- Less elaborate social behavior and organiation
*
Lemurs Characteristics
- 60 species
- Madagascar
- Good grasping ability
- good vision
- depth perception and color not as well develped
- Nals vs. Claws
- Single births
- Moist rhinarium
- Scent glands
- Attached upper lip
- Reflective layer on retina
Adaptive Radiation
An evolutionary phenomenon where a group of closely related organisims evolve morphological and behavioral features enabling then to exploit different ecological niches (exploit resources that other might not) (starting out from one point then they radiated out to many niches) (Example of this: Lemurs how they have radiated into different ecological areas and have evolved morphologial and behavioral to exploit different niches like becoming insecteverous, somenector, some fralevorous -plants, some granevours- seeds)
Characteriscs of Lorisidea
(Suborder: Strespsirhini)
Lorisidea
- 8-10 species
- Distributioin: Africa Asia
- Africa: pottos and Buschbabies
- Asia: Slow and slender lorises
*
Characteristics of Tarsiformes
- 5 species
- Distributioin Islands of South East Asia
- Prosimians-like characteristics
- small
- nocturnal
- insectivorous
- specialzed dentition
- unelaborated social behavior and organization
- Anthropoid-like characteristics
- decreased snout and olfaction
- no moist rhinarium
- closure of eye socket
- more rounded skull
- untethered uper lip
Anthropoid Characteristics
- Size: anthropoids tend to be larger than prosimians
- more generalized dentition
- brains more elaborate and larger relative to body weight
- better vision
- Olfaction: smaller snouts, less emphasis on smell
- Locomotion: not vertial clingers and leapers
- Each stage of development tends to be longer
- More complex social interactions and social organizations
- Temporal separation: use resources at different times
- Niche separation: exploit different ecological niches
- Spatial separation: groups maintain some from of separation in space
- Home range: the area used by a primate or primate group during a one year period
- Core area: the part, or parts, of a home range most extensively utilized
- Territory: a home range, or part of a home range, that is actively defended against conspecific
*
Benefits to live in a group large family
- protection
- physical
- safety in numbers (survalience)
- Some parts of enviornment is better suited if its exploited by a group instead of individual
- older primates remember past resources
- Because young take long time to become adult
- Social (need the attention of others)
- grooming
- hygenic: cleans ecto parasites
- lessons tensions
- to get close to female when ovulating
- Priniperous(first time mother) Prinimvorous(two or more times mother) used grooming to get close to priniperous to see baby*
- grooming
Monkey Evolutionary grade (OWM and NWM. Remember this is grade not taxonomy)
Old world monkeys and New wold monkeys
- infraorder: anthropoidea
- Parvorder: Plataride(flat rhini nose) (all new wold monkeys)
- Parvorder: Cladarides (down turn nose) (old world monkeys and apes)
- All monkeys have tails
- Larger from prosimians but smaller then apes
- quadrupedalism
OWM vs. NWM
OWM vs NWM 2
