Politics is applied biology. - Ernst Haeckel

I established the opposite view, that this history of the embryo (ontogeny) must be completed by a second, equally valuable, and closely connected branch of thought - the history of race (phylogeny). Both of these branches of evolutionary science, are, in my opinion, in the closest causal connection; this arises from the reciprocal action of the laws of heredity and adaptation... 'ontogenesis is a brief and rapid recapitulation of phylogenesis, determined by the physiological functions of heredity (generation) and adaptation (maintenance).

... It is a well-known fact that among all the recent investigations of none have yielded such grand and surprising results as the s which we owe to the English naturalists, , , , and others. While, twenty years ago, the depths of the ocean were supposed to be devoid of life, and an universally accepted dogma asserted that organic life ceased at a depth of two thousand s below the surface of the sea, the brilliant researches of English voyagers during the last ten years have proved the contrary. It has been found that the bottom of the sea, as far down as it could be investigated—to a depth of twenty-seven thousand feet— is thickly peopled with animals of various orders; for the most part with creatures hitherto unknown to science, and corresponding to that of the .
