Mine started when my first professional mentor invented what was hailed as the , which he invented in about 1968 and began to patent just before the crisis, and it . During that furor, I , spent absorbing its art and culture, and began . Dennis is 12 years older than I am, and as I dreamed of changing the energy industry, he had his in the energy crisis's mayhem. Brian began his alternative energy pursuit around the same time, as he engaged in activism and .

consist of body plans, which scientists have used to classify all life forms, and all significant animal phyla had appeared by the Cambrian Period’s end. The Cambrian Explosion has been difficult to explain and there is still great controversy and many unanswered questions, and it has also been difficult to explain why significant change stopped the explosion. Once the basic body plans appeared and biomes were filled, new plans never appeared again. Why did all fundamental change stop? The emerging view is the same for why complex life with and never changed since then. Not only could innovation confer great benefits, but , further travel along the developmental path made it continually less feasible to backtrack, start over, and take another path, or choose a fundamentally different path. The history of life’s choices was reflected in organisms in several ways, and the source of that inertia began to be understood when biology and chemistry at the cellular and subcellular levels were investigated, particularly after DNA was sequenced and studied. The fact that have not significantly changed in several hundred million years points to the issue. Hox genes have not changed because they control key developmental steps in embryonic development. Not only do Hox genes work, there are no practical ways to significantly change them, as they lay the animal’s structural foundation. Hox genes are called regulatory genes, and the nature of seems to be why animals have not fundamentally changed since the Cambrian Explosion.

What Is a Reflection Paper? - Reflective Essay

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.

But the branch of the that readers might find most interesting led to humans. Humans are in the phylum, and the last common ancestor that founded the Chordata phylum is still a mystery and understandably a source of controversy. Was our ancestor a ? A ? Peter Ward made the case, as have others for a long time, that it was the sea squirt, also called a tunicate, which in its larval stage resembles a fish. The nerve cord in most bilaterally symmetric animals runs below the belly, not above it, and a sea squirt that never grew up may have been our direct ancestor. Adult tunicates are also highly adapted to extracting oxygen from water, even too much so, with only about 10% of today’s available oxygen extracted in tunicate respiration. It may mean that tunicates adapted to low oxygen conditions early on. Ward’s respiration hypothesis, which makes the case that adapting to low oxygen conditions was an evolutionary spur for animals, will repeatedly reappear in this essay, as will . Ward’s hypothesis may be proven wrong or will not have the key influence that he attributes to it, but it also has plenty going for it. The idea that fluctuating oxygen levels impacted animal evolution has been gaining support in recent years, particularly in light of recent reconstructions of oxygen levels in the eon of complex life, called and , which have yielded broadly similar results, but their variances mean that much more work needs to be performed before on the can be done, if it ever can be. Ward’s basic hypotheses is that when oxygen levels are high, ecosystems are diverse and life is an easy proposition; when oxygen levels are low, animals adapted to high oxygen levels go extinct and the survivors are adapted to low oxygen with body plan changes, and their adaptations helped them dominate after the extinctions. The has a pretty wide range of potential error, particularly in the early years, and it also tracked atmospheric carbon dioxide levels. The challenges to the validity of a model based on data with such a wide range of error are understandable. But some broad trends are unmistakable, as it is with other models, some of which are generally declining carbon dioxide levels, some huge oxygen spikes, and the generally relationship between oxygen and carbon dioxide levels, which a geochemist would expect. The high carbon dioxide level during the Cambrian, of at least 4,000 PPM (the "RCO2" in the below graphic is a ratio of the calculated CO2 levels to today's levels), is what scientists think made the times so hot.
