Explain the difference between generalized and specialized characteristics. What are examples of each in terms of the adaptive potential? Define the term “adaptive radiation” and explain why it is important to the principle of evolution. Why was adaptive radiation especially important to mammals’ eventual rapid evolutionary success and diversification? What are some of the different groups of mammals?
Define natural selection using the 5 points below to explain its role in understanding primate behavior. (1) there is variation among individuals;   (2) some of that variation is heritable;   (3) there is always competition between individuals for resources;  (4) some variants outcompete other variants and leave more offspring;   (5) to the extent that the parent's traits are heritable, then a larger portion of the next generation will  reflect those traits.
Choose all of the correct statements about complex adaptations: Complex adaptations might evolve through a combination of of gene recruitment and promiscuous proteins. The parts of a complex adaptation may have evolved for a different function originally. Complex adaptations require all parts of the adaptation to evolve simultaneously. Complex adaptation do not evolve by natural selection. Complex adaptations are composed of multiple, different traits, such as behavior and physiology. Complex adaptations are 'irreducibly complex'. Complex adaptations are the result of parallel evolution. omplex adaptations always take thousands of years to evolve.
