Then came the Caenozoic age, or age of mammals, three million years, with strata thirty-one hundred feet thick. The god of life was getting in a hurry now; man was not far off. A new device, the placenta, was hit upon in this age, and probably the diaphragm and the brain of animals, all greatly enlarged.
Finally comes the Anthropozoic or Quaternary age, the age of man, three hundred thousand years, with not much addition to the sedimentary rocks. Man seems to be the net result of it all, of all these vast cycles of Palaeozoic, Mesozoic, and Caenozoic life. He is the one drop finally distilled from the vast weltering sea of lower organic forms.
We probably have little conception of how intimate and cooperative all parts of the universe are with one another, of the debt we owe to the farthest stars, and to the remotest period of time. We must owe a debt to the monsters of Mesozoic and Caenozoic time; they helped to fertilize the soil for us, and to discipline the ruder forces of life.
