Branching diagrams that map how organisms are related through evolution show their descent from common ancestors. These diagrams are called phylogenetic trees. They use branches to represent lineages and nodes at branching points to mark speciation events, making it possible to infer which species are more closely related based on shared ancestry. The term phylogeny specifically refers to the evolutionary history of a group of organisms, so a phylogenetic tree is the visual representation of that history. Among the given options, the idea that fits best is Phylogenic Trees, which corresponds to the concept of phylogenetic trees, even though the standard spelling is phylogenetic. The other terms describe ecological or geographic concepts (niche, endemic, habitat) and don’t capture the idea of evolutionary relationships.
