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. WebA phylogenetic tree is a diagram that represents evolutionary relationships among organisms. Phylogenetic trees are hypotheses, not definitive facts. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors. In trees, two species are more related if they have a more recent ...
