So far, this essay has dealt lightly with regional differences and largely confined the discussion to polar, temperate, and tropical conditions in the seas, and rainforest versus dryer conditions on land. While existed, barriers to species diffusion on land were relatively modest, hence dominance. But at the Triassic’s end, and continental differences in plants and animals often became significant in later times. Although the formation of Pangaea had profound impacts, because land life was relatively young, the differences and resultant changes due to the removal of oceanic barriers were less spectacular than would happen in the distant future, such as when .

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.

The Role of Computers in Modern Life - IMPORTANCE OF COMPUTER

With the above limitations acknowledged, this essay will explore the earthly journeys of life and humanity, and energy’s role in them.

At this juncture, I will ask my readers to perform an exercise that I first saw described by Peak Oil advocate , which is to lay aside data and graphs and just think about how energy makes everything in our daily lives possible. Think about your food, water, mode of transportation, and materials that comprise your home and possessions, and think of the role that energy played in providing them. Think about the energy that you use each day in powering your home and in your transportation, even if it is just walking. Then imagine running out of energy. When you flipped on a light switch, nothing happened. When you turned on the tap, no water came out. Your refrigerator stopped working, food deliveries to your community ceased, and no electricity, oil, gas, coal, or even wind or water power was available. Everything in your life would come to a sudden halt. When people have tried to demote energy below spirituality, social relations, or even made it irrelevant to economics, my question is for them to see what they can forego the longest: prayer/meditation, social interaction, sex, or energy. The fossil fuels burned to power industrial civilization provide several hundred energy slaves for each American and no less than hundreds per person in every industrialized nation. All that those energy-leveraged humans do is direct the energy, like holding the reins of a gigantic beast that each person rides each day. Airline pilots half-joke that they begin their workday by strapping jet airliners to their waists. Without that energy to direct in the myriad ways that industrialized humans use it, modern civilization would come to an abrupt end.

Complex life means, by definition, that it has many parts and they move. Complex life needs energy to run its many moving parts. Complexity’s dependence on greater levels of energy use not only applies to all organisms and ecosystems, but it has also applied to all human civilizations, as will be explored later in this essay. When cells became “complex” with organelles, a tiny observer inside that cell would have witnessed a bewildering display of activity, as mitochondria sailed through the cells via “scaffolding” on their energy generating missions, the ingestion of molecules for fuel and to create structures, the miracle of cellular division, the constant building, repair, and dismantling of cellular structures, and the ejection of waste through the cellular membrane. The movement of molecules and organelles in eukaryotic cells is accomplished by using the same protein that became muscle: actin. Prokaryotes used an , and their provide their main mode of travel, to usually move toward food and safety or away from danger, including predators.

No doubt, this is an age of computers, by computers and for computers.
