Question

Quizplus · Accepted Answer

The comparative method is used to determine the evolutionary relationships between species by analyzing their physical or genetic characteristics. It is important to consider how many times a trait evolved, rather than simply how many species possess the trait, in order to accurately infer relationships and construct a valid phylogeny. The other answer choices are incorrect.
