Answer 1

A branch point on a tree, often referred to as a phylogenetic tree or evolutionary tree, represents a point where a single lineage splits into two or more lineages. This indicates a common ancestor from which different species are derived. Thus, the correct interpretation of a branch point would be:

**Extinct common ancestors between two species (ancestros comunes extintos entre dos especies)**

This means that at the branch point, there was a common ancestor that has since evolved into different modern species.
