Whether these changes  occurred simultaneously or in some proximal sequence is unknown. Nor is it apparent which change occurred first, or what were the time frames in which they emerged.  Even more unclear is the issue of when these traits and habits were first incorporated into social mores and human values. It presents a puzzle with regard to human evolution and invites speculation. That provides a pivot point for the following discussion.

It is not a scientific term and it is not the same as “co-evolution” – the latter of which denotes an evolutionary trend whereby two separate creatures or biochemical entities evolve in ways that lead to a cooperative, adaptive interaction. (Futuyma & Slatkin, 1983), (Thompson, 1994). Congruence refers to the fact that in human evolution certain traits and behavioral/emotional dispositions had to occur either simultaneously or in close temporal proximity for them to jell into adaptive sexual, parental and social-familial dynamics.
