Vedclass · Answer

(A) The Assertion is correct because molecular homology,such as similarities in proteins (e.g.,cytochrome $c$) and genes across diverse organisms,provides strong evidence for common ancestry.The Reason is also correct because all vertebrates share a common ancestor and have evolved through adaptive radiation to occupy diverse niches,demonstrating great adaptation capability.Since the molecular evidence mentioned in the Assertion is a fundamental way to establish the evolutionary relationships that confirm the common ancestry mentioned in the Reason,the Reason correctly explains the Assertion.

$A$: Similarities in proteins and genes performing a given function among diverse organisms give clues to common ancestry.
$R$: All groups of vertebrates arise from a common ancestor with great adaptation capability.
