Evolution (Darwinian).
Darwin’s theory is that different forms of animal and vegetable life are due to small variations, and that natural selection is a main agent in bringing them about. If favourable, these variations are perpetuated, if not they die off.   1
   Spencer’s theory is that the present multitude of objects have all sprung from separate atoms originally homogeneous.   2
        “Evolution is the integration of matter and concomitant dissipation of motion, during which the matter passes from an indefinite, incoherent homogeneity to a definite coherent heterogeneity; and during which the retained motion undergoes a parallel transformation.”—Spencer: First Principles, part ii. chap. xvii. p. 396.
