WebOct 17, 2024 · The maximum phenotypic distance between any pair of ancestors (Dmax) is calculated, and compared with the phenotypic distance between the current putatively convergent taxa (Dtip). The greater the difference between Dmax and Dtip, the higher the index. C2 is the raw value of the difference between the maximum and extant distance … WebJan 30, 2008 · Schluter argued that the speed of divergence during character displacement is greatest when phenotypic distance (i.e., degree of similarity) between competing species is intermediate. In particular, while very similar species experience intense competition, the speed of divergence is not expected to be high, because an increase in phenotypic ...
Biological Distances and Population Genetics in Bioarchaeology
WebThe phenotypic distance measurement can subsequently be used to identify phenotypes based on the phenotypic distance between samples and negative controls, and perform clustering analysis based on the phenotypic distance between samples [8]. Multiple methods to compute phenotypic distance are implemented in this package. WebJan 1, 2016 · Bioarchaeologists have often used quantitative traits (cranial, dental, and skeletal measures) for standard distance measures, such as Mahalanobis's generalized distance, based on the idea that phenotypic similarity reflects genetic relationships. Since the 1980s, distance analysis has increasingly incorporated population-genetic models. honkai impact 3 seele
