Final answer:
On a phylogeny, each branch, or each bundle of branches with a common stem, is called a clade. False.
Step-by-step explanation:
False
A clade is a group of organisms that includes an ancestor and all of its descendants. It is a phylogenetic classification, based on evolutionary relationships. Each branch, or bundle of branches with a common stem, on a phylogeny is called a clade. However, it is important to note that not every branch on a phylogeny is a clade. Some branches may represent groups of organisms that do not share a common ancestor with the other organisms in the branch.
