Everyday life applications: cooking & food chemistry.

The Cambrian’s global ocean contained far less oxygen than today’s. Being newly and probably inconsistently oxygenated by oceanic currents was only part of the problem. The Cambrian oceans were warmer than today’s oceans, perhaps far warmer, such as 40o C and higher for the . Water’s ability to absorb oxygen declines as it gets warmer. Water heated from 10o C to 40o C will lose 40% of its ability to absorb oxygen. The phenomenon of warmer water absorbing less oxygen contributed to many instances of anoxic waters during the eon of complex life, and particularly in the warmer, earlier periods.

Another evolutionary concept is that all changes had mechanical reasons for happening (again, today’s science has ), and each mechanical change required some purpose in improving an organism’s chances of surviving to reproduce, or at least not have unduly impaired it. As evolution progressed, for each species, it was like taking a road, and the farther down the road a species went in its development, the “lifestyle” opportunities that its biological operation created precluded other kinds of styles. For instance, trees will never become . Trees went down the path of roots, , growing taller than their neighbors, and the like. A plant cannot choose locomotion as a way of life. It does not generate enough energy for it, for one thing. Animals went down a very different evolutionary path than plants did, and muscles, brains, livers, and the like have no analogy in plants and, by themselves, plants will not grow muscles or brains anytime soon, although humans have been making radical changes in animals over brief periods of time, such as the many breeds of dog.

The nutrient cycling that life contributes to, and the oxygen that is generated that maintains the ozone layer, was all initially performed by prokaryotes, and will continue to be performed by them long after complex life goes extinct. Complex life is largely unnecessary for making Earth inhabitable. Microbes do not need them. Earth’s biomass today is about half prokaryote and half eukaryote.

Although the overwhelming devastation of the Permian extinction seemed to play no favorites and whatever survived was the luck of the draw, recent research has demonstrated that even with such a catastrophe, certain life forms were more resilient than others, related to biological “buffers” in their life processes. In marine environments, the warming, anoxia, and acidification would have wiped out species vulnerable to them, and corals were and still are particularly susceptible to those changes. Those conditions wiped out the corals in the Permian extinction, and they are the first ecosystems being devastated today, with similar conditions of . Whether it was the ability to move to safer environs or the ability to buffer chemical changes, the more organisms had a better survival rate than others.

is complex, but the preceding presentation is largely adequate for this essay’s purpose, while it can be helpful to be aware that the physics behind FE and antigravity technologies will probably render the Standard Model obsolete. If FE, antigravity, and related technologies finally come in from the shadows, the elusive may come with them, and the Unified Field might well be consciousness, which will help unite the scientist and the mystic, and . But that understanding is not necessary to relate the story that White Science tells today of how Earth developed from its initial state to today’s, when complex life is under siege by an ape that quickly spread across the planet like a cancer once it achieved the requisite intelligence, social organization, and technological prowess.
