are created by undisturbed organism remains that become saturated with various chemicals, which gradually replace the organic material with rock by . Few life forms ever become fossils but are instead consumed by other life. Rare dynamics lead to fossil formation, usually by anoxic conditions leading to undisturbed sediments that protect the evidence and fossilize it. Scientists estimate that only about 1%-2% of all species that ever existed have left behind fossils that have been recovered. Geological processes are continually creating new land, both on the continents and under the ocean. Seafloor strata do not provide much insight into life’s ancient past, particularly fossils, because the process in “mere” . The basic process is that, in the Atlantic and Pacific sea floors in particular, oceanic volcanic ridges spew out basalt and the plates flow toward the surrounding continents. When oceanic plates reach continental plates, the heavier (basaltic) oceanic plates are subducted below the lighter (granitic) continental plates. Parts of an oceanic plate were more than 100 mya and left behind plate fragments. On the continents, however, as they have floated on the heavier rocks, tectonic and erosional processes have not obliterated all ancient rocks and fossils. The oldest “indigenous” rocks yet found on Earth are . have been dated to 3.5 bya, and fossils of individual cyanobacteria have been dated to 1.5 bya. There are recent claims of finding . The oldest eukaryote fossils found so far are of . The first amoeba-like vase-shaped fossils date from about 750 mya, and there are recent claims of finding the first animal fossils in Namibia, of sponge-like creatures which are . Fossils from might be the first animal fossils, and some scientists think that animals may have first appeared about one bya. The first animals, or , probably descended from . The is a tail-like appendage that protists primarily used to move and it could also be used to create a current to capture food. Flagella were used to draw food into the first animals, which would have been sponge-like. When the first colonies developed in which unicellular organisms began to specialize and act in concert, animals were born, and it is currently thought that the evolution of animals probably only happened . In interpreting the fossil record, there are four general levels of confidence: inevitable conclusions (such as ichthyosaurs were marine reptiles), likely interpretations (ichthyosaurs appeared to give live birth instead of laying eggs), speculations (were ichthyosaurs warm-blooded?), and guesses (what color was an ichthyosaur?).

By the 1850s, Germany was , and seminal discoveries and achievements came from German labs. As agriculture became industrialized, two nutrients were identified as key limiting resources as per : phosphorous and . Until 1909, humanity’s source of nitrogen for agriculture was manure. Guano was even the main source of nitrate for gunpowder when World War I began in 1914. After a century of failure by many eminent chemists, in 1909 made one of history’s most momentous breakthroughs when he . That energy-intensive process is responsible for half of humanity’s food supply today. It is also partly responsible for a great deal of water pollution, , and proliferation of weaponry. Haber has also been called the father of chemical warfare, as he was instrumental in , but he nevertheless won his Nobel Prize in 1918 for his nitrogen breakthrough. Phosphorus, which forms the , is the sole element that humanity has not found a substitute for in industrial civilization. Energy makes nitrogen and other elements more available or allows for substitution, while phosphorous must be mined or recycled. German chemical wizardry continued after World War I, and Germany was the center of science in the early 20th century. Relativity and quantum theory, the two pillars of today’s physics, were developed in Germanic nations, and Einstein, , , , , , and dominated physics in the early 20th century, with relatively minor contributions from American, British, and French scientists. From the first Nobel prizes awarded in 1901 to the rise of Nazi Germany in 1933, more than a third of the awards in and went to Germans, and if the Swiss, Dutch, Austrian, Danish, and Swedish laureates are added, they amount to well more than half, particularly for their theoretical work.

When I arrived at my office, I turned on my lights and computer. When I was eating, I put the food that I brought to work in a refrigerator under my desk. During my work day, I interacted with many people in my air-conditioned, high-technology office environment. My cellular telephone was never far away. The view from my office window of the was pleasant. My computer interfaced with our distant data centers and the world at large via the Internet. When my workday was finished, I rode the bus home. In the winter, the furnace is programmed to stop functioning when my wife and I leave for work, and comes on soon before we arrive home, so we never experienced a cold house. In the evening, we might watch a movie on a DVD on our wide-screen plasma TV. When I am not fasting, I usually eat dinner, with the food in my refrigerator usually purchased at a that has an enormous produce section, with food grown locally and imported from as far away as New Zealand, China, and Israel. We have a high-tech kitchen, with a “smart” stove, refrigerator, and other appliances.

chemical reaction photosynthesis lesson

In the early 19th century, a dispute was personified by , a British lawyer and geologist, and , a French paleontologist. Their respective positions came to be known as and . Just as , so did uniformitarianism prevail in scientific circles. Under the comforting uniformitarian worldview, there was no such thing as a global catastrophe. Changes had only been gradual, and only the present geophysical, geochemical, and biological process had ever existed. The British Charles Darwin explicitly made Lyell’s uniformitarianism part of his evolutionary theory and he proposed that extinction was only a gradual process. Cuvier was , which contradicted the still-dominant Biblical teachings, even in the . Although Cuvier did not subscribe to the , his catastrophic extinction hypothesis was informed by his fossil studies. But Lyell and Darwin prevailed. Suggesting that there might have been catastrophic mass extinctions in Earth’s past was an invitation to be branded a pseudoscientific crackpot. That state of affairs largely prevailed in orthodoxy until the 1980s, after the was posited for the dinosaurs’ demise. An effort led by a scientist publishing outside of his field of expertise (a ) removed from its primacy. Only since the 1980s have English-speaking scientists studied mass extinctions without facing ridicule from their peers, which has never been an auspicious career situation. Since then, many and mass extinction events have been studied, but the investigations are still in their early stages, partly due to a dogma that prevailed for more than a century and a half, and Lyell’s uniformitarianism is influential. The ranking of major mass extinctions is even in dispute, , and a was recently .

compare and contrast photosynthesis and cellular respiration essay

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.
