The evidence consists of observations that are compatible with a hypothesis. These observations must be collected systematically in an attempt to avoid the bias inherent to observations that has been used as evidence in the past. In this sense what we call evidence depends on its informativeness regarding the hypothesis and is presumed to be true used in support of the hypotheses that are presumed to be falsifiable. Therefore the evidence goes toward supporting a hypothesis.
Cladistics or phylogenetic systematics groups organisms by their share derived characters. Taxa that share many derived characters are grouped more closely together than those that do not. Tree-like relationship diagrams called "cladograms" results showing hypothesized relationships. The evidence that organisms are related comes from homologies between them. The observable parts, or attributes, of organisms which can be examined for homology are characters. Therefore In these hypothesized relationships, the characters are considered the evidence.
