The existence of switches that steer ontogenesis between disparate but functional developmental pathways raises the question of which came first – the switches or the pathways?
One might expect that since current orthodoxy maintains that biological processes of ontogenesis proceed differently from the selectionist processes of phylogenesis, evolutionary epistemologies would reflect this difference.
B.F. Skinner's theory of operant conditioning, which deals with the ontogenesis of individual behavior, is explicitly based upon the Darwinian selectionist model (Skinner 1981).
Nothing in evolution makes sense except in the light of phylogenesis, like ontogenesis, being a front-loaded, self-limiting, self-terminating planned process where the environment plays little if any role outside of providing triggers to proceed to the next stage of diversification.
And, if categories are not embodied, developmental 'products'. where do you see a link to ontogenesis?
In this highly influential account, masturbation, as Laqueur puts it, "became a part of ontogenesis: we pass through masturbation, we build on it, as we become sexual adults."
The smiling response: A contribution to the ontogenesis of social relations, with the assistance of K. M. Wolf.
It was both ontogenesis as the origin and development of an individual being, and the adaptation, in the nature of that individual, specifically to the exploration of ontogenesis, the origin and development of the individual being.
The state of being whose ontogenesis we explore has overwhelmingly included such experiences.
Haeckel (1874) replied by insisting that: “Phylogenesis is the mechanical cause of ontogenesis,” and would tolerate no opposition.
