The level of investment in defenses varies with resource quality, the intensity of herbivory (defenses can be induced; Schaller, 2008), and plant ontogeny (Boege & Marquis, 2005).
Ontogeny enzymatic studies can provide better knowledge of the physiology of nutrition during development, and they are essential for understanding larval nutritional needs.
The author describes his research at the Max Planck Institute of Evolutionary Anthropology, where he researched chimps, bonobos, and human children, and presents a neo-Vygotskian theory of human ontogeny. His theory synthesizes ideas from cognitive science, child development, human evolution, and comparative psychology to create a new framework for understanding the growth of the human mind and emotions in the first seven years of life.

This latter point is not up for debate as the racial core component reflecting phylogeny, in theory, is supposed to be preeminent to the peripheral component reflecting ontogeny. In other words, phylogeny lays the foundation, direction, and parameters for ontogeny.
