单选题The history of mammals dates back at least to Triassic time. Development was retarded, how- ever, until the sudden acceleration of evolutional Line change that occurred in the oldest Paleocene. This (5) led in Eocene time to increase in average size, larger mental capacity, and special adaptations for different modes of life. In the Oligocene Epoch, there was further improvement, with appearance of some new lines and extinction of others. (10) Miocene and Pliocene time was marked by culmi- nation of several groups and continued approach toward modern characters. The peak of the career of mammals in variety and average large size was attained in the Miocene. (15) The adaptation of mammals to almost all pos- sible modes of life parallels that of the reptiles in Mesozoic time, and except for greater intelligence, the mammals do not seem to have done much bet- ter than corresponding reptilian forms. The bat is (20) doubtless a better flying animal than the pterosaur, but the dolphin and whale are hardly more fishlike than the ichthyosaur. Many swift-running mam- mals of the plains, like the horse and the antelope, must excel any of the dinosaurs. The tyrannosaur (25) was a more ponderous and powerful carnivore than any flesh-eating mammal, but the lion or tiger is probably a more efficient and dangerous beast of prey because of a superior brain. The significant point to observe is that different branches of the (30) mammals gradually fitted themselves for all sorts of life, grazing on the plains and able to run swiftly (horse, deer, bison), living in rivers and swamps (hippopotamus, beaver), dwelling in trees (sloth, monkey), digging underground (mole, rodent), (35) feeding on flesh in the forest (tiger) and on the plain (wolf), swimming in the sea (dolphin, whale, seal), and flying in the air (bat). Man is able by mechani- cal means to conquer the physical world and to adapt himself to almost any set of conditions. (40) This adaptation produces gradual changes of form and structure. It is biologically characteristic of the youthful, plastic stage of a group. Early in its career, an animal assemblage seems to possess capacity for change, which, as the unit becomes (45) old and fixed, disappears. The generalized types of organisms retain longest the ability to make adjust- ments when required, and it is from them that new, fecund stocks take origin—certainly not from any specialized end products. So, in the mammals, we (50) witness the birth, plastic spread in many directions, increasing specialization, and in some branches, the extinction, which we have learned from obser- vation of the geologic record of life is a characteris- tic of the evolution of life.
