ANT101H5 Chapter Notes - Chapter 6: Brachiation, Color Vision, Haplorhini
Document Summary
But kept a lot of ancestral mammalian traits. Limos+ locomotion: tendency to have an erect posture especially upper-body, generalized locomotor anatomy -> not restricted to 1 form of movement, prehensile hinds (and feet) by-> retention of 5 digits on hands/feet. Tactile pads at tips of digits = better sense of touch. Lack of dietary specialization: generalized definition -> related to a) Sense and brain -> they rely on vision > smell: color vision-> characteristic of diurnal primates, depth perception by-> eyes on front of face. Visual info from eyes transmitted to left + right c) Primate adaptations evolutionary factors-> adaptation to arboreal living, lead to shift to omnivory geological distribution + habitats-> found in tropical/ semitropical areas diet + teeth-> lack of specialization = omnivory . Lack of specialization in size + shape of teeth locomotion almost all are quadrupedal. Brachiation aka arm swinging + using prehensile tail. Primate classification primates -> stepsirhini ( lemurs + lorises)
