the answer is a branching tree.
A branching tree is a diagram that shows how scientists think different groups of organisms are related.

A Branching tree
A phylogenetic tree is a diagram that shows how scientists think different groups of organisms are related. It illustrates the evolutionary relationships among different species or groups based on shared characteristics and genetic information. Phylogenetic trees help to visualize the evolutionary history and common ancestors among organisms.
A branching tree diagram divides organisms into groups based on their shared characteristics and evolutionary history. Organisms that share more recent common ancestors are grouped closer together on the tree, while those that diverged earlier are placed farther apart. This hierarchical system allows for the classification and organization of diverse organisms into related groups.
I think you mean phylogeny. Phylogeny is the evolutionary history of a species or group of related species.
To identify organisms and determine how groups are related.

In the English language, there are a huge variety of names for groups of animals and groups of plants and groups of people.See the "What are the names for various groups of animals?" for some of them.Typically such groups have members that are related to each other.The special case of a group of organisms that are genetically identical to each other -- which happens in the wild with many kinds of plants and bacteria, and a very few species of animals -- is called a clonal colony.
Groups of similar organisms within a species are called populations. Populations consist of individuals of the same species that can interbreed and share a common geographical location.
