CVA Final Exam (Answered) 2022 Graded A+ evolution changes in the genetic makeup of populations of animals through time - change in genetics eventually leads to changes in phenotype recapitulation similarities in embryonic developmental stages of different species is evidence that the embryos are repeating the developmental stages of the ancestors mosaic evolution parts of the body can change independent of others homology similarity in organs from different organisms as a result of inheritance from COMMON ancestors analogy functional similarity among non homologous organs (like butterfly and bird wings) Darwin's reasoning behind natural selection -animals have high reproductive potential and if unchecked will deplete resources -heritable variation between organisms -competition for resources allows the most fit attributes to be passed on with survivors monophyletic group a group with the ancestor and all of its descendants character states various forms of individual attributes derived characters evolutionarily changed and used to delineate relationships transformation series change in character states through time within a clade (ex transition to land) outgroup analysis used to assess patterns of change by establishing polarity (direction of change) outgroup taxa
