By 1836 the anatomist Richard Owen had theories influenced by Johannes Peter Müller that living matter had an "organising energy," a life-force that directed the growth of tissues and also determined the lifespan of the individual and of the species. In the 1850s Owen developed ideas of "archetypes" in the divine mind producing a sequence of species in "ordained continuous becoming" in which new species appeared at birth.
