Autapomorphic

So cladistics is a reductive method, stripping a defined set of taxa, that have for sure one trait in common, of all distinguishing, autapomorphic traits to arrive at sets of plesiomorphic traits that are common to all taxa in the monophylitic clade. ❋ Unknown (2009)

Or maybe he meant that the taxa listed above share characters that are autapomorphic for the listed genera in his analysis. ❋ Darren Naish (2006)

The variability was restricted to very few differences in sequence length and autapomorphic changes. ❋ Hubert Turner Et Al. (2010)

Additionally, the prominent offset proximal hook of the deltopectoral crest is autapomorphic for ❋ Joseph J. W. Sertich Et Al. (2010)

The distinct, plate-like medial process of the scapula contributing posteriorly to the glenoid surface is autapomorphic. ❋ Joseph J. W. Sertich Et Al. (2010)

Tibia robust; proximal articular condyle sub-equally expanded; cnemial crest projects cranially then laterally (autapomorphic); ovoid distal articular surface; distal breadth more than twice that of mid-shaft. ❋ Scott A. Hocknull Et Al. (2009)

Ulna with straight caudal margin, inflated olecranon process; lateral groove along diaphysis (autapomorphic); round and discontinuous lateral tuberosity. ❋ Scott A. Hocknull Et Al. (2009)

Fibula expanded proximally; intermediate robusticity (autapomorphic); distal articular surface bevelled cranio-medially. ❋ Scott A. Hocknull Et Al. (2009)

(autapomorphic); deltopectoral crest prominent, extending to mid-shaft; proximal border shallowly sigmoidal; proximo-lateral corner square; distal condyles merged and flat extending only just onto anterior face of shaft; proximal breadth 50% of total length. ❋ Scott A. Hocknull Et Al. (2009)
