Vedclass · Answer

(A) The study of blood groups,specifically the $ABO$ blood group system,provides molecular evidence for evolutionary relationships.Humans and apes (such as chimpanzees and gorillas) share the presence of $A$ and $B$ antigens in their blood,which are absent in monkeys.This biochemical similarity indicates a closer evolutionary lineage between humans and apes compared to monkeys,supporting the theory of a common ancestor.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: Blood group analysis shows that human beings are more closely related to apes than to monkeys.
$R$: The blood groups $A$ and $B$ are found in apes but not in monkeys.
