Question

what do you understand by the term phylogenetic relationships?

Answer 1

Phylogenetic relationship refers to the relative times in the past that species shared common ancestors.

Answer 2

“Phylogenetic relationship” refers to the relative times in the past that species shared common ancestors. Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).
