Answer:
Phylogenetic (evolutionary) Tree
showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor.
• Each node is called a taxonomic unit.
• Internal nodes are generally called hypothetical
taxonomic units
• In a phylogenetic tree, each node with
descendants represents the most recent
common ancestor of the descendants, and the
• edge lengths (if present) correspond to time
estimates.
Explanation:
Phylogenetic trees are usually based on morphological or genetic homology. A comparison of anatomical traits can reveal an evolutionary relationship among species. Taxonomy, the science of classifying organisms, is based on phylogeny. Early taxonomic systems had no theoretical basis; organisms were grouped according to apparent similarity.
