For example, neutral human DNA sequences are approximately 1.2% divergent (based on substitutions) from those of their nearest genetic relative, the chimpanzee , 1.6% from gorillas ...
The term is relative; a trait considered an apomorphy in one clade may not be considered an apomorphy in a different clade. Contrast plesiomorphy . An apomorphy is a derived trait present in one or more members of a clade but not the common ancestor; a plesiomorphy is an ancestral trait present in the common ancestor of the clade and possibly ...
