  • adjective biology Describing any characteristic that has evolved in only a single species (or other taxon)


Sorry, no etymologies found.


  • 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.

  • Or maybe he meant that the taxa listed above share characters that are autapomorphic for the listed genera in his analysis.

  • The variability was restricted to very few differences in sequence length and autapomorphic changes.

  • 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.

  • (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.
