Why should evolution be understood as a branching tree rather than a straight ladder?
Answer and explanation
Correct answer: Because different groups change in different directions in different environments
Evolution is not a ranking system in which every organism moves toward a single superior endpoint. Populations share ancestors and may diverge when they experience different environments, resources, or selection pressures. Each lineage can follow its own adaptive pathway, producing branches. Therefore, option B correctly describes branching evolution; the other choices wrongly treat humans as the universal goal or reject variation.
