What is the cladogram phylogenetic tree clade node?

A cladogram is a diagram that represents the evolutionary relationships among various biological species based on shared characteristics. In this tree, a clade is a group of organisms that includes an ancestor and all its descendants, forming a branch on the tree. Each node on the cladogram represents a common ancestor from which the descendant species diverged. By analyzing these nodes and branches, scientists can infer the evolutionary history and relationships of different species.
