Question

Evolutionary theory predicts that species are related, not independent. Four of the following examples provide support for this prediction. Which one of these examples does not support the claim that species are related?

A.Plants that live in desert regions typically have thickened leaf surfaces to prevent water loss. B.The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins. C.All prokaryotes and eukaryotes use DNA to carry their genetic information. D.Ground squirrel species found on the north and south sides of the Grand Canyon are similar behaviorally, despite being very different physically. E.Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease

Answer 1

A.Plants that live in desert regions typically have thickened leaf surfaces to prevent water loss.

Step-by-step explanation:

Evolutionary theory states that species evolves over time which are interrelated to each other with little modifications and adaptations with the surroundings.

Evolutionary theory also predicts that the species evolved are not independent in nature but they are related to one another. In all the options B, C, D and E shows the relationship between two species which are inter related to one another which have adapted to its environment.

But option A shows that only deserts plants have thick leaves surfaces which prevent loss of water from its surface. Thus it does not support the fact that the species are related.

Hence the correct option is (A).
