Now, you could be a hard-bodied linebacker, or you could be a sumo-sized layabout; there are many different body types, so buying shirts just by neck size and arm length is necessarily inexact.

Continued speciation will generate groups of closely related species. A clade is a group of species that includes an ancestral species and all of its descendants (Figures 3, 4). Clades (also called monophyletic groups), like species, are formed by the process of descent with modification.
1. a group of people related by blood or marriage or a strong common bond, such as those descended from a common ancestor, or a husband, wife, and their children. 2. a taxonomic category below an order and above a genus.
