Evolution is Non-directed Sickle-Cell Anemia A severe hereditary form of anemia in which a mutated form of hemoglobin distorts the red blood cells into a crescent shape at low oxygen levels. It is most common among those of African descent—where malaria-infected mosquitoes live. Negative aspects: Can be fatal for those infected; Positive Carriers (as opposed to people that are infected) are immune to malaria; survival and reproduction Primates (Biology and Behavior) Class: Mammalia (mammals) Order: Primates Old suborders: Prosimii (before the monkeys i.e. lemurs, lorises, ) and Anthrop Athropoidea oidea (human-like i.e. monkeys, apes, humans) New suborders (based on rhini: “nose”): strepsirhini (“turned nose”) and haplorhini (“simple nosed”) Haplorhini: 2 Infraorders within Athropoidea: Platyrrhini: “New World monkeys”; grasping monkey; arms are same length; prehentile Catarrhini: rough callas on backside; “Old World monkeys and the apes”

Unformatted text preview: Terrestrial: on the ground; bigger; catarrhini Arborial: typically platyrrhini; smaller; eat food high off tree tops (hence size and speed) Sexual Dimorphism: difference in size between the sexes. Similarities among primates: Grasping hands: 5 fingers Grasping feet: minus humans (evolved out of that); 5 digits Opposable thumbs Smell to sight: we look at things (primary knowledge) and then smell them (secondary knowledge). Binocular vision: both eyes form one field of view Stereoscopic: each eyeball is connected to both sides of the brain BOTH form depth perception. Nose to hand: then your hand collects additional information. Primate Brain: Big Complex Enlarged cerebral hemisphere (3 main advantages of ECH) 1. Center of conscious thought 2. Good for memory: even collective (shared) memory 3. Association...
