Document Summary
K selected : know the primate life history pattern. In general, primates have long life histories: small litters, slow development, long gestation, long lactation/infancy period, long lives, etc. Strepsirrhines: relatively fast life history compared to haplorrhines. Monkeys: slower life history than strepsirrhines but faster life history than apes. Apes: very slow life history: learn about primate birth and infancy. Infancy in non-human primates: single, generally unassisted births. Exceptions: callitrichids, humans: the obstetrical dilemma in humans. Humans have very large brains but also a narrow birth canal (due to bipedalism) This looks labor and delivery very difficult. Very early birth (altricial infants: maturity at birth. Physically helpless at birth birth: primate infants altricial (and costly) Tarsiers, monkeys, apes, and humans: most infants are carried 24-7. Continuous opportunity to learn through observation and experience: care of primate infants. Milk lower quality: new infants often draw attention from other group members, natal attraction.
