Answer: Cladogram
Explanation: A cladogram is a diagram used by scientist to represent a phylogeny , which is a hypothetical relationship between groups of animals. It shows groups of organisms, how they are compared and related and their common ancestors.
It consists of the organisms, lines and nodes found where those lines cross. The lines represent evolutionary time that lead to the population it connects to, while the nodes represent common ancestors between different species.
At a certain point in the past, a population of common ancestor organisms may be divided, and this gives rise to the different organisms.
