What is the usual meaning of close branches in an evolutionary tree?
Answer and explanation
Correct answer: Their common ancestor may be relatively recent
An evolutionary tree is a diagram of hypothesised relationships among lineages. When two branches join at a comparatively recent branching point, the organisms represented by them may share a more recent common ancestor than organisms whose branches meet farther back. Therefore option A is correct, although a tree does not mean the organisms are identical or that one is automatically superior. B, C, and D contradict the purpose of such a tree.
