Evolutionary theory predicts that species are related, not independent. Four of the following examples provide support for this prediction, but one is irrelevant. Which of examples listed below does not support the claim that species are related? A.Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous. B.Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease. C.The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins. D.All prokaryotes and eukaryotes use DNA to carry their genetic information. E.Ground squirrel species found on the North and South sides of the Grand Canyon are very similar to each other.

Evolution is the process by which an organism inherits or adapts favourable characteristics that prolong its survival in the living world. Nature automatically selects best fit individuals from a population that can evolve and transfer the characteristics to their progeny. Evolution is a time taking process that takes hundreds of years to become significant.We can say that one organism is related to the other when we see that the features of one organism are also present in another organism, or when features of one organism are derived from another organism. The structure of insulin is common in both humans and pigs, hence they support the theory. Also, the development of thyroid glands in lancelets and vertebrates are common. Hence, they also support this theory. We all know that eukaryotes have evolved from prokaryotes. Also, ground squirrel species found in different geographical locations are also related. But, when an organism becomes extinct, it cannot continue or evolve into more developed organisms on Earth. Hence, the correct option is (a) Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous.
