key term - Phylogenetic analysis

Definition

Phylogenetic analysis is a method used to infer the evolutionary relationships among various biological species or entities based on their genetic, morphological, or behavioral characteristics. This analysis utilizes algorithms and statistical models to create phylogenetic trees that represent these relationships, which are essential in understanding the evolutionary history and biodiversity of life forms.
