It observes the tiny cell on the surface of an egg yolk, and watches it divide and multiply until it becomes a great mass of cells, which group of? Or differentiate, and rearrange and alter their shapes. It observes how little organs unfold them selves, or evolve out of these little cell groups - how gradual, but how unvarying the change; how one group becomes a bone, another a brain, another a muscle, to constitute in three short weeks the body of a matured chick. Those little tendons like silken threads, that run down those slender pink legs to each and every toe, and move its little joints so swiftly that we hardly see them that little brain, no bigger than a tiny seed, in which is planted a mysterious force that impels it to set all those brand-new muscles in motion, and to dart after a fly with the swiftness of an arrow - all this wondrous mechanism, all this beauteous structure, all this perfection of function, all this adaptation to environment, have evolved from a few microscopic cells in three short weeks.

Biology is the science that observes all this, and enunciates the law that the life-history of this animal cell.
