Document Summary
Survey of living primates grouped in simia (included monkeys and primates) Shared with mammals: fur, homeothermy, longer gestation, live births, mammary glands, heterodonty, increased brain size, ability for learning and behavioural flexibility. Unique: relatively little because primates are very generalized physically - they are defined more by behavioural traits than physical ones. Living non-human primates live in tropical and sub-tropical conditions throughout the. Americas, africa, and asia about 230 different species range from around 1 ounce to 400 pounds according to the fossil record, share an ancestor at about 65 m. a. , with the first fossil primate found existing around 55 m. a. (pleisiadapis) Primate adaptations: habitat rainforest (tropical and sub-tropical conditions) in the old and new worlds species also exist in near-desert conditions, or very cold ones (japanese macaques have the northernmost distribution) Galagos are quick leapers can jump vertically (6. 5 feet from a standstill)
