"To trace that life in its manifold changes through past ages to the present is a... difficult task, but one from which modern science does not shrink. In this wide field, every earnest effort will meet with some degree of success; every year will add new and important facts; and every generation will bring to light some law, in accordance with which ancient life has been changed into life as we see it around us to-day."

O.C. Marsh,
Vice Presidential Address, AAAS, August 30, 1877
