Why is it more correct to see evolution as a branching tree rather than a straight ladder?
Answer and explanation
Correct answer: Because different lineages change in different directions
Evolution is not a fixed ladder in which every organism progresses toward one final form. A population may split into separate lineages, and different environments, variations and selection pressures can produce different adaptations in those lineages. These divergences are represented by branches of an evolutionary tree, so A is correct. The other options incorrectly assume human-directed progress, value judgments about age, or absence of branching.
