“Spencer's theory is that the present multitude of objects have all sprung from separate atoms originally homogeneous."
“ Evolution is the integration of matter and concomitant dissipation of motion, during which the matter passes from an indefinite, incoherent homogeneity to & definite coherent heterogeneity; and during which the retained motion undergoes & parallel transformation.”-Spencer: First Principles, part ii. chap. xvii. p. 396."

(2) The Sun-amoeba is multicellular, with an organism adapted for sensation, digestion, and the power of reproduction. (3) Then will come the Gastrula, an organized being, with an external mouth. (4) Next the Hydra or Polyp, which has localized sense-organs and instincts. (5) Then the Medusa, with nerves, muscles and nerve functions.
