QUESTION 1 1 points (Extra When Darwin wrote On the Origin of S some would be found. On which of the following concepts was Darwin basing his bold prediction? Select all that apply no transitional fossils had been discovered, but Darwin predicted that A- Individual organisms can change from one form to another,like a fish becoming a land animal, and give rise to new species. The transitional forms must therefore exist in the fossil record. B. All major groups of organisms living today descended from preexisting groups. There must therefore be fossils with features that link different major groups, both living and extinct, to one another. C. Darwin reasoned that eventually the fossils of all organisms that ever existed would be discovered and that there would have to be some transitional forms among them. Major transitions in the history of life occur over long periods of time and in small steps rather than major leaps, with groups of animals evolving traits that did not exist in the ancestral groups. QUESTION 2 1 points (Extra The 150-million-year-old A characteristics sthat we associate with living reptiles. Which of the following are considered reptilian characteristics of Archaeopterya?

Explanation / Answer

Please find the answers below:

Answer 1: Choices B and D (Darwin's theory of evolution was based upon two major facts. Primarily, all organisms have descended from the same parent organism and hence share similarities in the features. Secondarily, the course of evolution is a slow and steady process and hence, slow transitions from one form to another do take place, hence intermediate transitional form of organisms must exist)

Answer 2: Choices C and D (The presence of teeth in the mouth is a reptilian character, along with a long slender backbone which supports the long structure of the reptile for balancing its body. Presence of claws and wings is a bird-like feature)
