The nodes in cladograms represent divergences or speciation events.
Explanation:
The nodes on the trees indicate the common ancestors of descendants.
At each node a splitting event occurs. The node therefore represents the end of the ancestral taxon and the stems , the species that split from the ancestor. The two taxa that split from the node are called sister taxa.
