Camel Spider Zoology (Colorado)

An autapomorphic trait is one that is found in one and only group.  Wikipedia gives the following definition: an autapomorphy is a distinctive anatomical feature, known as a derived trait, that is unique to a given terminal group. 

The autapomorphic species concept is one of 26 ways scientists have used to distinguish species from each other.

Examples[]

Autapomorphy has been applied to studies of human evolution where Kennedy (1991) found that on this basis of discrimination Homo erectus could not be considered a distinct species.

Paleotologists will use autapomorphic traits to help identify new species found through fossil discovery.
