Synomorphy, which is the degree of fit between a behavior setting and the individuals within it, is an important concept for understanding Staffing Theory. When a place is high in synomorphy, the number of people and the types of tasks being performed match what the behavior setting provides, and the individuals can achieve maximum productivity ...
Transformed cladistics, also known as pattern cladistics is an epistemological approach to the cladistic method of phylogenetic inference and classification that makes no a priori assumptions about common ancestry. It was advocated by Norman Platnick, Colin Patterson, Ronald Brady and others in the 1980s, but has few modern proponents.
In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). [2][3][4] A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor. [1][5][3][6][7][8][9] In cladistics ...
Willi Hennig. Emil Hans Willi Hennig (20 April 1913 – 5 November 1976) was a German biologist and zoologist who is considered the founder of phylogenetic systematics, otherwise known as cladistics. [1][2][3] In 1945 as a prisoner of war, Hennig began work on his theory of cladistics, which he published in German in 1950, with a substantially ...
The yellow tail is a plesiomorphy and symplesiomorphy for all living species. In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades. Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy, all mean a ...
Cladistics (/ kləˈdɪstɪks / klə-DIST-iks; from Ancient Greek κλάδος kládos 'branch') [ 1 ] is an approach to biological classification in which organisms are categorized in groups (" clades ") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ...
Criticisms of the labour theory of value. Criticisms of the labor theory of value affect the historical concept of labor theory of value (LTV) which spans classical economics, liberal economics, Marxian economics, neo-Marxian economics, and anarchist economics. As an economic theory of value, LTV is widely attributed to Marx and Marxian ...
Appearance. The calcichordate hypothesis holds that each separate lineage of chordate (Cephalochordates, Urochordates, Craniates) evolved from its own lineage of mitrate, and thus the echinoderms and the chordates are sister groups, with the hemichordates as an out-group. [ 1 ] It was formulated by British Museum paleontologist Richard Jefferies.
