Examples

  • 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.

    A Disclaimer for Behe?

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