NEXT CHAPTER: PRIMATES Primate Adaptive Trends: What it is to be a primate 1. have mammary glands to create milk for babies 2. fur for heat insulation, sweat glands (homeothermy) maintaining of body temperature 3. several different kinds of teeth—incisors, canines, premolars and molars 4. large brain size, esp. the neocortex 5. the placenta and long gestation period followed by a live birth easier to define primates as mammals as compared to traits that make primates specifically special from all mammals the single special anatomical characteristic that defines primates: petrosal bulla basically just a bone that grows around to protect the middle ear also high degree of grasping ability in the hands and feet they have opposable toes and hands, although every species has a different hand shape and grasp primates have nails rather than claws—means they can touch more things b/c claws don’t really let you touch things (like the idea of hooves vs. paws). also primates have more sensitive pads w/ skin ridges on feet and hands—creates friction for better grip
