Step 1

A clade is a group of organisms that includes a common ancestor and all its lineal descendants. Similarly, a monophyletic group is a group of organisms that consists of all the descendants of a common ancestor. Show more…

Key Concepts

Monophyletic Group

A monophyletic group is synonymous with a clade. It is defined by its inclusion of an ancestral species and all of its descendants, ensuring that all members of the group share a single common ancestor that is not shared with other groups.

Phylogenetic Tree

A phylogenetic tree is a diagram used in evolutionary biology to illustrate the relationships among various species, showing how they have diverged from common ancestors over time. The tree structure clearly demonstrates the branching pattern of evolution and the formation of clades.

Clade

A clade is a grouping in evolutionary biology that includes an ancestor and all its descendants, representing a single branch on the phylogenetic tree. This complete lineage embodies the concept of common ancestry and is central to understanding evolutionary relationships.
