External climate change. . . . . Internal physiologic evolution

To gain a full understanding of the relationship between climate change and physiology we must transcend the superficial Anthropic Principle, that we are ‘in’ this Universe, and enter the world of ‘Goldilocks’ who was seeking the ‘just right’ condition in the home of the three bears. What she was actually looking for was homeostasis, that balance that epitomizes all of Cosmology. It is the ‘equals’ sign in all balanced equations, whether it's physics, chemistry or biology. It represents the resolution of the Big Bang, which disrupted the Singularity thought to have pre-existed it, giving rise to asymmetries. We emulate that effort through Symbiogenesis - the assimilation of factors in the environment that have posed existential threats - as the means of evolution in response to climate change. Such a ‘true’ narrative is tantamount to gaining control of our runaway climate.
