Excerpt from INITIATIVE IN EVOLUTION
"Initiative in animal evolution comes by stimulation, excitation, and response in new conditions, and is followed by repetition of these phenomena until they result in structural modifications, transmitted and directed by selection and the laws of genetics-a series of events which agree with Neo-Lamarckian principles."
