Document Summary

Adaptive radiation - cluster of closely related species that are each adaptively specialized to a specific habitat or food source. Advanced characters - a new version of a trait found in the most recent common ancester of a group. Analogous - performing a smiliar function but has different evolutionary origins. Eg. wings of a bird and a bat. Apomorphy - trait that is shared by two or more taxa and their most recent ancestor. Is a derived character within a group. Artificial taxonomy - a prominent or easily observed feature is taken as the mark of resemblance or dissemblance. Autoapomorphy - derived trait that is unique to a given group. Found in only one member of a clade --> not in any other groups or taxa. Has pigmented cells that can detect light. They wrap around each other into cups and the cup closes with a pinhole.
