单选题Both plants and animals of many sorts show remarkable changes in form, structure, growth habits, and even mode of reproduction in becom- Line ing adapted to different climatic environment, (5) types of food supply, or mode of living. This divergence in response to evolution is commonly expressed by altering the form and function of some part or parts of the organism, the original identity of which is clearly discernible. For (10) example, the creeping foot of the snail is seen in related marine pteropods to be modified into a flapping organ useful for swimming, and is changed into prehensile arms that bear suctorial disks in the squids and other cephalopods. The (15) limbs of various mammals are modified according to several different modes of life—for swift run- ning (cursorial) as in the horse and antelope, for swinging in trees (arboreal) as in the monkeys, for digging (fossorial) as in the moles and gophers, (20) for flying (volant) as in the bats, for swimming (aquatic) as in the seals, whales, and dolphins, and for other adaptations. The structures or organs that show main change in connection with this adaptive divergence are commonly identified (25) readily as homologous, in spite of great altera- tions. Thus, the finger and wristbones of a bat and whale, for instance, have virtually nothing in common except that they are definitely equivalent elements of the mammalian limb.
