Question

Quizplus · Accepted Answer

Phylogenetic trees with proportional branch lengths indicate relatedness among organisms, the relative number of nucleotide pair differences between groups, and they are constructed by comparing DNA sequences of homologous genes and calibrating this molecular clock with the fossil record. Therefore, all the answer choices are true. They also allow for estimating evolutionary time.
