XXXV. 100 In other articles I propose to deal with the origin and significance of larval forms, and to draw attention to some further examples of the influence of larval characters upon adult organisation, to which I apply the term ‘Pædomorphosis’. 1932J. S. Huxley Probl. Relative Growth vii. 240 (caption) Diagram to illustrate positive and negative mutations in rate-factors, leading to recapitulation and paedomorphosis, respectively. 1965B. E.
