摘要:

AbstractThe phylogenetic species concept is applied for the first time to a major radiation of birds, the birds‐of‐paradise (Paradisaeidae) of Australasia. Using the biological species concept, previous workers have postulated approximately 40–42 species in the family. Of these, approximately 13 are monotypic and 27 are polytypic with about 100 subspecies. Phylogenetic species are irreducible (basal) clusters of organisms (terminal taxa) that are diagnosably distinct from other such clusters. Within the context of this concept, approximately 90 species of paradisaeids are postulated to have diversified within Australasia. The phylogenetic species concept more accurately describes evolutionary diversity within the family and provides a better theoretical and empirical framework for analysing speciation, historical biogeography and patterns of morphological, behavioral and ecological diversification within this group than does the biological species co

摘要:

Abstract—The order of states in a transformation series describes an internested set of synapomorphies. States adjacent to each other in the transformation series thus share a degree of homology not found in the other states. Whether the level of homology is relatively apomorphic is determined by rooting the order with outgroup comparison. The analysis of state order is a homology problem and is solved with a two‐step process using similarity and congruence with other characters as criteria. Other methods that have been proposed (e.g. transformation series analysis, non‐additive analysis, morphocline analysis, ontogenetic analysis) fail to apply both similarity and congruence, and thus cannot be used independently for determining character state
