BIOL 3040 Study Guide - Cultural Learning, Stridulation, Parallel Evolution
Document Summary
19. 1 coevolution and mutualism: define coevolution and explain why coevolution differs from evolutionary change in a single species i. e. , intraspecific vs. interspecific interactions, coevolution. Parallel evolution of 2 species in which changes in heritable traits in one lad to changes in heritable traits in the other: intraspecific, interspecific other. Interactants share the same gene pool; natural selection acts on alternate alleles in the gene pool. One muted and one pupae secrete food for the ants stridulating (vibrating: explain how cospeciation may occur between taxa involved in a mutualistic relationship. Obligate mutualism: mutualism in which each partner requires the other for successful survival and reproduction: glochidion tree flowers pollinated by epicephala moths. Larvae feed on seeds: females pollinate flowers, describe how species involved in a mutualistic relationship might prevent cheating", plants react to n2 fixing bacteria that cheat by reducing the growth rate.
