Q: What are phylogenetically independent contrasts, and why are the useful?

Solution

Answer:

Phylogenetically Independent Contrasts is a way of integrating the increasing availability of phylogenetic trees with comparative biology.

Phylogenetic independent contrasts is a generalization of the paired comparisons method where contrasts are taken for each node in a phylogenetic tree using only paired tip values.

The process of Phylogenetically Independent Contrasts method:

1. Obtain a phylogeny of interest

2. Measure traits of interest and compare sister taxa

3. Test for correlated evolution traits in contrast to sister taxa

Phylogenetically Independent Contrasts is a method to analyze trait correlations and informations from all species in the phylogeny can be used for part of the analysis.

Thus, it is a technique for accounting for shared common ancestry when using the comparative method to find trends and patterns in evolutionary events. It helps to understand natural selection when we account for the shared evolutionary history among the species we are studying.
