Just as the aftermath of the appearance of complex life was uninteresting from a , as the amazingly diverse energy-generation strategies of archaea and bacteria were almost totally abandoned in favor of aerobic respiration, biological solutions to the problems that complex life presented were greatest during the Cambrian Explosion, and everything transpiring since then has been relatively insignificant. Animals would never see that level of innovation again. While investigating those eonic changes, many scientists have realized that the dynamics of those times might have been quite different from today’s, as once again may be of limited use for explaining what happened. Also, scientists generally use a rule-of-thumb called , or parsimony, which states that with all else being equal, simpler theories are preferred. , a seminal theorist regarding the scientific method, as they were easier to falsify. However, this issue presents many problems, and in recent times, theories of or speciation have invoked numerous interacting dynamics. Einstein noted that the more elegant and impressive the math used to support a theory, the less likely the theory depicted reality. Occam’s Razor has also become an unfortunate dogma in various circles, particularly , in which the of materialism and establishment science are defended, and often quite irrationally. Simplicity and complexity have been seesawing over the course of scientific history as fundamental principles. The recent trend toward multidisciplinary syntheses has been generally making hypotheses more complex and difficult to test, although and ever-increasing and more precise data makes the task more feasible than ever, at least situations in which are not interfering.
show that some animals were mobile before the Cambrian Explosion. Sponges were probably the but they were immobile except for their flagella drawing water through them, which carried food and oxygen in and waste out. The first creatures that we would recognize as animals were probably worms crawling atop ocean sediments. As lowly as the worm might seem, it would have needed muscles, bilateral symmetry, a circulatory and digestive/excretory system, and a nervous system run by a brain; that distant ancestor probably possessed . Some early worms may have even had rudimentary eyes. And of possibly eonic importance, worms probably made the first poop. The evolution of may have been a seminal event in the organic carbon burial process. Sponges may have also been largely responsible for initially removing oceanic carbon, which helped increase atmospheric oxygen and helped ventilate the oceans. Until then, organic carbon from dead life forms would not have settled to the ocean floor, but would have floated in the water column and been recycled by other life forms. Although the hypothesis , feces sinking to the ocean floor may have been how life’s burial of carbon began, as well as robbing sulfate-reducing bacteria in the water column of their nutrients and thus enabling oceanic waters to remain oxygenated. Ediacaran fauna did not burrow into ocean sediments, but deep burrowing was characteristic of Cambrian sediments. There is debate today whether Cambrian burrowing was a of oxygenating the ocean floor.
During the Cambrian Explosion, an ecosystem developed in which life on the sea floor, surface, and water column all interacted for the first time. All but one of were energy dynamics, as the environment provided either too much or too little energy, and the nutrient hypothesis () will be revisited numerous times in this essay. A lack of nutrients, mineral and otherwise, always meant that the energy-driven dynamics that delivered the nutrients were curtailed. If enough energy is properly applied, all nutrients can be abundant.
Lucifer rebelled and transgressed against the Lord God and became the first created being to sin. Lucifer sinned a long, long time ago before Adam or his world was even created. The earliest (thus first) documented sin (and documented in the Holy Scriptures we should add) occurred countless eons ago. It certainly happened sometime before the Cambrian geologic period (about 500 -600 million years ago), because that is where we see an explosion of well-developed life forms in the fossil record. Things that are alive don't leave remains UNTIL they DIE. The marks where multiple very complex life forms first began to appear and die in the Earth's fossil record of geologic natural history.
