The node in a cladogram represents the formation of a new species. The formation of a new species is termed as a speciation event.
The node in cladogram indicates the point at which a splitting event, or formation of a new species occurred.
The line between two nodes is called the internode. It represents at least one hypothetical ancestor.
A cladogram is a tree shaped diagram that is used to illustrate evolutionary relationships among species by analyzing some similarities or differences in physical features and other kinds of characters in the organisms.
