A character is any recognizable trait, feature, or property of an organism. Evolutionary biologists are interested in a character's heritability.

Character polarity is the issue of the evolutionary history of a character: given two character states, which we call a and a' , we need to know whether a evolved from a' ' or the other way round. Discerning character polarity is a fundamental task of phylogeny.
