It is defined as the concepts and methods for determining the branching patterns of evolution and evolutionary h, tonsils and _____________________________. thus vestigial structures can be viewed as evidence for evolution: organisms having vestigial structures probably share a common ancestry with organisms in with organisms in which the homologous structure is functional, protein found in mitochondria; used in study of evolutionary relationships because most animals have this protein; made of 104 amino acids joined together, # of amino acid differences compared to human cytochrome c- horse, # of amino acid differences compared to human cytochrome c- tuna, # of amino acid differences compared to human cytochrome c- frog, # of amino acid differences compared to human cytochrome c- shark, # of amino acid differences compared to human cytochrome c- turtle, # of amino acid differences compared to human cytochrome c- monkey, # of amino acid differences compared to human cytochrome c- rabbit. Homologous structures have similar morphology but have different functions. As technology evolved, allowing scientists to study life at the genetic level, these categories have been updated to include domain, the broadest categoryin the taxonomichierarchy.

However different dolphins and sharks are structurally and physiologically, they have evolved to be similar in function. A:Recombinant DNA technology Not until the latter half of the 20th century, when it became possible to analyze and compare DNA, could researchers reaffirm the evolutionary relatedness of species with homologous structures.

The hips and legs are slender, as they do not usually support any body weight. The hypothesis stands that if two structures have similar morphology but are used for different purposes, both organisms have evolved from the same origin, or are derived from a common ancestor.
