Locomotion: Brachiation (Suspension) Forelimb dominated, Flexible shoulder and wrist, hook hands.
Dental Adaptations For: Insectivory Points cusps on Molars-Altered Digestive tract
Locomotion: Arboreal Quad- Quadruped, Live in Trees, Shorter limbs, Flexible Joints, Ball socket joints are round/shallow, broad shoulder blades.
Locomotion-Terrestrial Quad- Longer Limbs, Stiff Joints, Ball and Socket are deeper, Shoulder Joints are broader and not flexible.
How have the joints of an Arboreal Quad Adapted to life in trees? Explain? The Ball and Socket of their Joints are flexible, they rotate 360.
Locomotion-Vertical Clinging and Leaping Jumping form trees, Hindlimb dominates.
True or False? Many Primates the Practice Vertical Clinging and Leaping are only Haplorrhines. False, they are mostly Strepsirrhines.
True or False? Spider Monkeys and Orangutans are True Brachiators? False, True Brachiators are Gibbons and Siamangs. Spider Monkeys and Orangutans are Semi-Brachiators. (they don't have as many adaptations).
Locomotion: Knuckle Walking- Quadrupedal Locomotion, Terrestrial.
Apes that practice knuckle walking: Bonobos, chimps, gorillas, and Orangutans.
True or False? Knuckle Walking is Terrestrial? True
True or False? Brachiation is Swinging through trees? False. Swinging through trees is Vertical Clinging and Leaping.
Interbirth Interval- Time Between Births
What theory states that: Males evolve traits to gain access to females, and Females evolve to provide food? Darwin's Theory of Sexual Selection.
What are the 5 Mating systems? Solitary, Monogamous, Polyandry, Polygyny, Dispersed Polygyny.
Mating Systems: What is Solitary, what is its's level of, Level of Sexual Dimorphism. Individual, low Sexual Dimophism.
Mating Systems: What is Monogamous, what is its's level of, Level of Sexual Dimorphism. One Male an One Female who mate for life. Low Sexual Dimorphism.
Mating Systems: What is Polyandry, what is its's level of, Level of Sexual Dimorphism. One Female and multiple males, both care for infants. Low Sexual Dimorphism.
Mating Systems: What is Polygyny, what is its's level of, Level of Sexual Dimorphism. One male and many females, High Sexual Dimorphism.
Mating Systems: What is Dispersed, what is its's level of, Level of Sexual Dimorphism. Mother and Child are a units, the Male and Female only come together to mate. High Sexual Dimorphism.
Primates that Practice a Solitary Social System: Most Strepsirrhines
Primates that Practice a Solitary Monogamous Social System: Gibbons, Marmosets
Primates that Practice a Solitary Polyandrous Social System: Tamarins
Primates that Practice a Solitary Polygynous Social System: Langurs, Gorillas, Howlers, Baboons
Primates that Practice a Solitary Dispersed Social System: Orangutans
True or False? Sexual dimorphisms are physical or behavioral differences within the sexes: False
True or False? Monogamous Primates Have the Highest sexual dimorphism? False, Monogamous Primates have the Lowest Sexual Dimorphism. The Primates with the Highest Sexual Dimorphism practice Single male, Multi Female Polygyny.
What is Modern Evolutionary Synthesis? Unification of Multiple scientific fields.
What fields Does Modern evolutionary Synthesis Unify? Biology, Genetics, Paleontology, and Ecology.
What Epoch are we in? The Halocene?
When did the continents reach their current locations? 30 Million Years ago.
What is Arboreal Hypotheis? Proposed Early Primates branch off into other mammals, living in trees
Visual Predation Hypothesis: Evolved Certain traits in connection to feeding on high quality, mobile prey.
Angiosperm Radiation Hypothesis: Diversity in flowering plants and fruits, and the ability to eat fruits led to evolution of primates to frugivores.
What evidence supports he Angiosperm Radiation hypothesis? Grasping Hands, Visual Acuity, Expansion of Molars.
