The scientific background:

A phylogenetic tree is a branching diagram showing the inferred evolutionary relationships among various biological species or other entities, based upon similarities and differences in their physical or genetic characteristics.
The taxa joined together in the tree are implied to have descended from a common ancestor.
Each node with descendants represents the inferred most recent common ancestor of the descendants. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed and they are the points in time when one species diverged in to two.


What does the branching out in a phylogenetic tree represent?
