What does it suggest when two branches are very close in an evolutionary tree?
Answer and explanation
Correct answer: Their common ancestor was likely relatively recent
An evolutionary tree represents lines of descent and relationships among organisms. If two branches split close to one another, the organisms on those branches are interpreted as having a relatively recent common ancestor. This does not mean they are identical organisms or that they lack genes; it only indicates closer evolutionary relatedness. Thus, option B gives the correct inference.
