WebPhenetics (as numerical taxonomy) emerged in the late 1950s, its origin associated with, among others, Charles Michener, Arthur Cain, and especially Robert Sokal and Peter Sneath. In Sokal and Sneath's (1963) Principles of Numerical Taxonomy, any evolutionary approach is avoided in favor of an operational method based on a direct comparison of phenotypes. is german an official language in macau https://tlcperformance.org
