Evidence of Evolution 31. A biologist analyzes the DNA sequences in three different primates. The biologist finds that primates "A" and "B" have almost exactly the same DNA sequences. The DNA sequences in primate "C" are significantly different from those of primate "A" and primate "B". Which of the following conclusions can be logically drawn from this information? A. All three primates appeared on Earth at about the same time B. Either primate "A" or primate "B" must be a direct ancestor of primate "C" C. Primates "A" and "B" are more closely related to each other than either is to primate "C" D. Primate "C" must have been the ancestor of both primate "A" and "B" Tail 32. Which of the following best explains how scientists are able to explain the presence of the femur and pelvis in a whale (refer to the image)? Backbone A. Humans evolved from whales B. The ancestors of whales once had femurs and pelvises Raza C. Whales will be able to walk on land in the future D. Whales need the femur and pelvis to swim Polvis Femur 33. Wings have evolved independently many times on earth. Bats, birds, and moths each use these structures. to fly but do not share a recent common ancestor. Which of the following are these structures referred to as? A. Analogous structures B. Homologous structures C. Vestigial structures
