C.
It shows that all species are related to each other.
D.

In contrast, humans last shared a common ancestor with New World monkeys about 40 million years ago. What could be concluded about evolutionary relationships among these groups? A. Humans are more closely related to Old World monkeys than to New World monkeys. B. Old World monkeys are more closely related to humans than to New World monkeys. C. Both A and B are correct. D. Neither A nor B is correct. Explain.arrow_forwardOne hypothesis for the Cambrian explosion was an increase in predator-prey relationships. It is thought that the resulting co-evolution of predator and prey may have been a factor in the rapid speciation of animals seen during this time.

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.
