Unformatted text preview: Analogous structures-Have similar functions & superficially similar appearance, but different anatomies (convergent evolution) Homologous structures: vertebrate embryos-All vertebrates share similar developmental genes-Differences arise by some genes being expressed differently Homologous Structures: Biochemistry & Molecular Biology-DNA is universal genetic material-All life forms use approximately the same 20 amino acids to make proteins -All use ATP as the primary form of cellular energy-All use RNA and ribosomes to make protein Biogeography-Geographic distribution of species-Closely related species tend to be found in the same region-Convert evolution-Organisms evolved from different ancestors, but living in similar environments-They evolve analogous structures...
