Example of phylogenetic bracketing

WebAug 31, 2024 · The process of identifying vestigial organs may rely upon tracing the evolution of a structure across a phylogenetic tree of genetic relationships. This process is often referred to as phylogenetic bracketing (Witmer 1995 ). Following this approach, characters are mapped onto a phylogenetic tree. WebAug 31, 2015 · A phylogenetic bracketing approach only requires confirmation of a character state in two successive sister taxa ( Witmer, 1995 ), but we included a third so as to increase the reliability of the inference.
