Question

complete the statement below. the first branch on an evolutionary tree is... the common ancestor. the adaptation. the most recently evolved. the most complex.

Explanation:

An evolutionary tree (phylogenetic tree) represents the evolutionary relationships among organisms. The first branch point (the one indicated by the arrow) shows the common ancestor from which different lineages diverged. Adaptation is a trait that helps an organism survive and reproduce. The most recently evolved and most complex would be at the tips of the branches, not at the first branch.

Answer:

the common ancestor.
