Phenotypic vs phylogenetic
WebAccording to Sneath and Sokal (1973) phenetic relationship means similarity or resemblance based on a set of phenotypic characters. Cladistic relationship means expression of the … WebPhylogenetic trees can come in different shapes. When interpreting phylogenetic trees, the shape and position of branches do not matter. What is important is how the branches are connected. Phylogenetic trees are intended to reflect patterns of descent and do not necessarily show phenotypic similarity or the absolute ages of organisms or groups.

WebAfter discussing some general approaches used to infer adaptation at different phylogenetic scales, we will explore phenotypic plasticity. This phenomenon has the potential to obscure patterns of adaptive evolution and can actually be a product of adaptation itself. Figure 9.1: Giraffe in Tsavo.
