WebBiodiversity is usually plotted as taxonomic richness of a geographic area, with some reference to a temporal scale. Whittaker [1] described three common metrics used to measure species-level biodiversity, encompassing attention to species richness or species evenness : Species richness - the simplest of the indices available. Simpson index. WebThe rate of evolution is measured as follows: Suppose that a character has been measured at two times, t 1 and t 2 ; t 1 and t 2 are expressed as times before the present in millions of years. The time interval between the two samples can be written as:Dt = t 1 - t 2,
