Document Summary

Review session monday, november 16, 2009, 6-8pm in 108 bessey hall. You should be able to define these terms as well as use them as examples to explain related terms and concepts. Allometry- differnet rates of growth for different parts of the body. (not all tissues/body parts grow at the same rate). For example: head height to body length at birth is 1:4, but in adults it is. Adaptation to walking involved modification/evolution of toes, legs, spine, pelvis, and muscles. Cladistics/cladistic analysis- counts only shared derived traits, ignores shared primitive traits. Evolutionary relationships between organisms are used to form biological classifications. Answer= optimal fitness is lifetime reproduction, allocation of time and energy, and the scheduling and implementations of important life events. convergent evolution- independent evolution of similar adaptations in rather distinct evolutionary lines. Ex: different wolfs with similar brain sizes (powerpoint) derived traits- traits that have changed from an ancestral state.
