An evolutionary attractor is a state toward which evolution tends.[1][2] Most often it means that adaptation is moving a population of a species towards a particular goal – that goal is the attractor.[1][2] It less commonly means any other outcome of evolution and/or a larger group than one population.

Attractors are important to evolutionary epidemiology because what goal a pathogen is pursuing – and its speed of progress towards more transmissible and/or more virulent attractors – radically alter the actual damage a pathogen will do.[1][3][2] It also shapes the course of a species invasion.[1]
