Evolutionary Distance

Abstract

Evolutionary distance refers to the cumulative evolutionary change between two DNA or protein sequences that were derived from a common ancestral sequence.

Keywords: distance measures; substitution models; distance estimation; nucleotide substitution; amino acid substitution

(a) One‐parameter model of nucleotide substitution. In this model, the rate of substitution in each direction is α substitutions per site per unit time. (b) Two‐parameter model of nucleotide substitution. In this model, the rate of transition (α) may not be equal to the rate of each of the two types of transversion (β).
