1- Evidence of exploitation suggests that the mechanisms of inheritance, accompanied by plectron, allow qualify over many generations 1. Outline the impact on the phylogeny of plants and animals of: - Changes in somatogenic conditions of the environment - Changes in chemical conditions in the environment - disputation for resources Changes in an environment kitty overhaul to opposite characteristics macrocosm selected as favourable. Changes in an environment can be physical (temperature change), chemical (change in water salinity) or competition for resources (food, shelter, friction match etc) 2. Describe, using specific examples, how the system of ontogeny is supported by the following atomic itemise 18as of study - Palaeontology, including fossils that have been considered as transitional forms study of past life forms shows past life and trends e.g. Archaeopteryx bird liking reptile, has characteristics of both and supports the theory that b irds evolved from reptiles. - Biogeography- distribution patterns of a species, reveals uncouth ancestors and divers(prenominal) evolution e.g. the trans pacific distribution of waratahs - Comparative embryology- studies resembling embryos in several(predicate) species of vertebrates, as the embryos are similar it suggests a common ancestor etc e.g.
humans, fish, lizard - Comparative anatomy- studies similar limbs in vertebrates, which show a that each evolved from common ancestor to item the needs of the species e.g. the pentadactyl limb - Biochemistry- studies similar chemical structures in unalike s pecies 3. apologize how Darwin/Walla! ces theory of evolution by infixed selection and isolation accounts for divergent evolution and convergent evolution Isolation- if several groups of the equivalent species become isolated from each separate the environments in which the groups are isolated may result in selection of different characteristics. Divergent evolution- evolution of different species from common ancestors who live in separate environments, this is...If you want to get a full essay, baffle it on our website: BestEssayCheap.com
