Question

what do we call the organism that is the ancestor of multiple new species that are formed as a result of evolution? different ancestors common ancestor

Explanation:

In evolutionary biology, a common ancestor is an organism from which multiple new species have evolved. Different ancestors would imply separate lineages with no shared origin for the new species in question. The diagram likely represents a phylogenetic tree where the common ancestor is the starting point (as indicated by the arrow) from which divergence occurs to form new species.

Answer:

common ancestor
