Unformatted text preview: wings of ostriches-Homologous structures: features that are similar in structure but appear in different organisms and have different functions Example: Forelimbs of tetrapod vertebrates (humans, bats & moles)- Analogous structures: structures that perform a similar function but are not similar in origin Example: Wings of bat (have bones), wings of insects (only membranes)-----These evolved separately 5. Biochemistry- Comparisons of the DNA or RNA of different species produce biochemical evidence for evolution. - DNA Sequence Analysis: The more related two organisms are, the more similar their DNA will be- Pseudogenes: Sequences of DNA that no longer function, but are still passed on through generations. Similarities reflect a common ancestor- Protein Comparisons: Cells from different species that have the same proteins most likely came from a common ancestor...
