Similar anatomy found in different species may be homologous (shared due to ancestry) or analogous (shared due to similar selective pressures). Molecular similarities provide evidence for the shared ancestry of life.

WebA dichotomous key is an important scientific tool, used to identify different organisms, based the organism’s observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification. WebThey will use taxonomy. It's a centuries-old science, used to identify species. First, they examine specimens of the organism, try to see whether it matches known species, and then use molecular biological assay techniques to further identify, if needed, its place in evolutionary history. This is normal science.
