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. 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 very similar to each other. e. before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease.
