An essay or paper on The Journey of Life
This essay is intended to draw a comprehensive picture of life on Earth, the human journey, and energy's role. The references that support this essay are usually to works written for non-scientists or those of modest academic achievement so that non-scientists can study the same works without needing specialized scientific training. I am trying to in a tiny fraction of the global population. . My hope is that the energy issue can become that tiny fraction's focus. Properly educated, that group might be able to help catalyze an energy effort that can overcome the obstacles. That envisioned group may help humanity in many ways, but my primary goal is manifesting those technologies in the public sphere in a way that nobody risks life or livelihood. I have seen too many wrecked and prematurely ended lives (, ) and plan to avoid those fates, for both myself and the group’s members.
For this essay’s purposes, the most important ecological understanding is that the Sun provides all of earthly life’s energy, either (all except nuclear-powered electric lights driving photosynthesis in greenhouses, as that energy came from dead stars). Today’s hydrocarbon energy that powers our industrial world comes from captured sunlight. Exciting electrons with photon energy, then stripping off electrons and protons and using their electric potential to power biochemical reactions, is what makes Earth’s ecosystems possible. Too little energy, and reactions will not happen (such as ice ages, enzyme poisoning, the darkness of night, food shortages, and lack of key nutrients that support biological reactions), and too much (such as , ionizing radiation, temperatures too high for enzyme activity), and life is damaged or destroyed. The journey of life on Earth has primarily been about adapting to varying energy conditions and finding levels where life can survive. For the many hypotheses about those ancient events and what really happened, the answers are always primarily in energy terms, such as how it was obtained, how it was preserved, and how it was used. For life scientists, that is always the framework, and they devote themselves to discovering how the energy game was played.

Here is a brief summary of this essay. Ever since more than three billion years ago and about a billion years after the Sun and Earth formed, organisms have continually invented more effective methods to acquire, preserve, and use energy. after three billion years of evolution and, pound-for-pound, it used energy . The story of life on Earth has been one of , and in turn influencing them. During the eon of complex life that began more than 500 million years ago, there have been many brief for some fortunate species, soon followed by increased energy competition, a relatively stable struggle for energy, and then cleared biomes and set the stage for another golden age by organisms adapted to the new environments. Those newly dominant organisms were often marginal or unremarkable members of their ecosystems before the mass extinction. That pattern has characterized the journey of complex life over the past several hundred million years. among some animals, which provided them with a competitive advantage.
Intense has existed in situations in which scientific and technological advances can threaten economic empires, but many areas of science are not seen as threatening, and reconstructing Earth’s distant past and the journey of life on Earth is one of those nonthreatening areas. I have never heard of a classified fossil site or a Precambrian specialist being threatened or bought out in order to keep him/her silent. There is more controversy with human remains and artifacts, but I am skeptical of popular works that argue for technologically advanced ancient civilizations and related notions. Something closer to “pure science” can be practiced regarding those ancient events without the threat of repercussions or the enticements of riches and . Much of this essay’s subject matter deals with areas in which the distortions of political-economic racketeering have been muted and the theories and tools have been unrestricted.

This essay has presented Earth’s many changing faces during its journey. Earth had molten beginnings, was , and may have . Later, and and . Earth experienced swings from to conditions as atmospheric gases dramatically changed, continents moved, and vast and of complex life played out on land and sea. But the changes happened over timescales of millions and billions of years, not hundreds. No climate scientist will deny that carbon dioxide traps infrared radiation and warms Earth’s atmosphere. The vented enough carbon dioxide into the atmosphere to create 200 million years of Greenhouse Earth conditions, when reptiles ruled Earth. Volcanism waned and around 150-to-100 mya. By 35 mya, and the Antarctic ice sheet began forming. Every paleoclimate study I have seen places greenhouse gas (and primarily carbon dioxide) concentrations as the primary determinant of global surface temperatures, after the Sun's radiation, but the Sun's output is considered to have been exceptionally stable and has risen slowly over the eons. , usually by accentuating the carbon dioxide with a positive feedback effect that may have reached runaway conditions at times.
I am taking some liberties in calling Turkana Boy a ; he is technically a member of , which is often considered ancestral to , which is the Asian variant’s name. There is great debate regarding how the human family tree branches between and . Some call the various -type species all subspecies of , while others argue for several distinct species. I will not stray far from the orthodox narrative here, for good reason. The reconstructed early human tale is based on very limited evidence, but that evidence will only grow over time, and the tools and techniques for using them will become more sophisticated. Although there may be some upcoming radical changes in the view of the early human journey, efforts of countless scientist and fossil hunter lifetimes support the narrative that this essay sketches, and I respect their findings and opinions, even though I acknowledge many limitations. The human ego, it seems, becomes more involved as the story of life on Earth moves closer to its human chapters.

Could this essay's first half be considered an indulgence of my childhood fascination with nature? That argument could have merit, but I have always been a "big picture" kind of thinker, even as a teenager. I am writing this essay primarily to help manifest FE technology in the public sphere and help remedy the deficiencies in all previous attempts that I was part of, witnessed, heard of, or read about. The biggest problem, by far, was that those trying to bring FE technology to the public had virtually no support from the very public that they sought to help. My journey's most important lesson was that , and an egocentric humanity living in scarcity and fear is almost effortlessly manipulated by the social managers. John Q. Public is only interested in FE technology to the extent that he can immediately profit from it. Otherwise, he goes back to watching his favorite TV show. It took many years of disillusionment for that to finally become clear to me. While this essay and all of my writings are provided for free to humanity and anybody can read them, I intend to only reach a very tiny fraction of humanity with my writings, but that tiny fraction will be sufficient for my plan to succeed. The readers that I seek have a formidable task ahead of them, but nothing less is required for my approach to have any hope of bearing fruit. This essay and my other writings are intended as a course in (also called "big picture") thinking. Studying the details deeply enough to avoid misleading superficial understandings is also a key goal. I am an accountant by profession, but one of the world's leading paleobiologists surprisingly read an early draft of this essay and informed me that it was one of the best efforts that he ever saw on the journey of life on Earth. There was nobody on Earth whose opinion I would have respected more than his, so I do not think that I am asking readers of this essay's first half to humor me. Every sentient being on Earth should know the rudiments of what this essay's first half covers.

Mass extinction events may be the result of multiple ecosystem stresses that reach the level where the ecosystem unravels. Other than the meteor impact that destroyed the dinosaurs, the rest of the mass extinctions seem to have multiple contributing causes, and each one ultimately had an energy impact on life processes. The processes can be complex and scientists are only beginning to understand them. This essay will survey mass extinction events and their aftermaths in some detail, as they were critical junctures in the journey of life on Earth.

In the 1990s, I found the dating issue enthralling and saw it assailed by fringe theorists and by . A couple of decades later, I reached the understanding that, like all sciences, dating has its limitations and the enthusiasm for a new technique can become a little too exuberant, but dating techniques and technologies have greatly improved in my lifetime. Dating the , and using 100,000-year increments to place the dates, may seem a conceit, thinking that scientists can place that event with that precision, but over the years my doubts have diminished. When and can be tested, and the findings support not only Earth’s age previously determined by myriad methods, but also support the prevailing theories for the solar system’s and Moon’s formation, call me impressed. Controversies will persist over various finds and methods used, and scientific fraud certainly occurs, but taken as a whole, those converging lines of independently tested evidence make it increasingly unlikely that the entire enterprise is a mass farce, delusion, or even a conspiracy, as many from the fringes continue to argue. There is still a , and it is not a parody. I have looked into fringe claims for many years and few of them have proven valid; even if many were, their potential importance to the human journey was often minor to trifling. As the story that this essay tells comes closer to today’s humanity, orthodox controversies become more heated and fringe claims proliferate.
