Rama09 [41]

Answer: Node

Explanation:

Cladograms are a graphical representation of the evolutionary relationship between organisms. These are usually shown as branches from a central point, which represents a common ancestor. In rooted cladograms, the branches are shown relative to the time elapsed since evolving from a common ancestor joined at the node, or point of divergence.

Evolution typically occurs after accumulating mutation, and natural selection of beneficial traits that confer greater chances for survival.
