Hub genes represent an important element of gene network architecture and their existence is empirically confirmed.
They recommended that explicit measures of the environment in systems terms be incorporated, and they proposed the existence of empirically assessable mechanisms proximal processes through which genetic potentials for effective psychological functioning are actualized.

Note, however, the following: the compartmentalization of theories and their concepts or vocabulary into levels neglects the existence of empirically meaningful and causally explanatory relations between entities or properties at different levels.
In addition, the existence of empirically determined circuits responsible for specific functions (such as, movement associated with exploratory behavior, egg laying, etc). in the C. elegans nervous system, raises the intriguing possibility that structurally defined modules are associated with definite functional roles [27].

In the words of someone who has spent time with people near the top of the pyramid, this sense of anxiety is like the curvature of the universe: you cannot see it, but its existence can be proven empirically.
