Question

Which describes closely related species?

a.They have similar DNA sequences.
b.They develop through similar pathways.
c.Their physical appearances are similar.
d.Their protein structures are different.

Answer 1

A. They have similar DNA sequences. closely related species have similar DNA sequences because they share a common ancestor. Over time, the DNA sequences gradually diverge as evolutionary changes occur, resulting in less similarity between less closely related species.
