a) Francis crick- Discovered the structure of that DNA that it's shaped like a twisted ladder and understood the way it replicates. b) Rosalind Franklin- She discovered the dimension of DNA strand and that the phosphate group was on the outside of the helical structure. c) James Watson- Together with Francis they discovered the structure of DNA and that he also discovered that hydrogen bonds were the correct length and were straight.…
They mixed gasses they thought would be on original earth. The electro-shocked it to simulate lightning, and they realized that amino acids showed up, the base of regular proteins. Iron-Sulfur World Hypothesis Günter Wächtershäuser, the scientist who made this theory, had the idea the earliest biomolecules originated involving forms of, iron and sulfur. He believed that metabolism, producing energy through certain processes, created more compounds as it grew. He and Claudia Huber mixed a bunch of chemicals and found that if you heat them at 100…
In the article, “How Sue Became a Rock Star,” written by Gail Mitchell Emilsson and Michael Tinnesand, it starts out by describing what is found around skeleton bones from many years ago. Rocks have formed around the the skeleton bones. These bone looking rocks are known as fossils. Fossils have helped us record and know about the life before us. Sue Hendrickson discovered the most completed and largest T-Rex ever found.…
In the beginning, all it took was one scientist named, Walter Alvarez, to spur a whole scientific community into looking for more and more evidence regarding the mass extinction including the dinosaurs between the Cretaceous and Tertiary periods. The pathway all started with a surprising observation, Walter had unearthed a thick claystone layer that was devoid of all fossils which the level only containing a much smaller number of fossils. Armed with this evidence, Walter started asking around, first with his own father Luis Alvarez. From there they came up with a hypothesis and brought in Richard Muller. With each new discovery, Walter’s team grow to include physicist and chemists.…
George Gaylord Simpson (1902-1984), an American paleontologist who moved often from New York's American Museum of Natural History, where he was curator, to lecture halls and also to visit far away fossil fields that weren't open to the public. His total understanding and grasp of the fossil record allowed for significant advances in theoretical evolution and taxonomy. To further explain the previous paragraph the reader must understand a few terms. A curator is in charge of keeping up with museum records and, in George Simpson's case, the manager of collections related to fossil records.…
Gerblitzel the Carbon Atom lived billions of years ago in the age of the dinosaurs in Russia. Gerblitzel lived in skies and one day he traveled through the stomates of the leaf and lived there. One day Gerblitzel was out on one of the leaves and he had his amazing view of the dinosaurs as they ate their breakfast of plants and trees when he realized that one of them was coming his way. He was scared and jumped but he thought, “well, I guess there must be hundreds of plants around what are the chances he chooses me”? But sure enough, the dinosaur reached it’s head down and opened it’s large mouth.…
Asteroid? Or Planet? William Herschel an astronomer in the march of 1781 observed a comet coming towards the earth. With scientific mind that he had he decided to ask make some measurements to be sure that the comet truly was coming towards the earth. In His calculations he decided it was, but the comet never did actually come.…
Usually these descendants are long deceased, as evolution continues through time. It was interesting in the case of the sea-coelacanth, that this fish, which was thought to be an ancient ancestor of four legged vertebrate such as humans, was still around and able to be examined in modern day. This is where the term “living fossil” originates, it is not that it is an actual living fossil, but it is a very close example to how an ancestral fish from millions of years ago appeared. It was intriguing to read how the coelacanth swam so differently from the way fish are known to swim.…
Imagine finding fossils of an undiscovered sauropod while adventuring with some friends. Well that is what happened to Elmer S. Riggs. He discovered the first fossils of the Brachiosaurus. In 1900, Riggs found a partial skeleton of a Brachiosaurus in the rocks of the Brushy Basin Membrane of the Morrison Formation. The fossils were studied and information on this species was revealed.…
Major Players Socrates Many people knew of Socrates in ancient Greece but few knew the reach his teachings had and how it would impact the world. We don't know much from Socrates himself, many of the informational texts we have about his life were written by his students and playmakers; Plato, Xenophon and Aristophanes. Many of the elders Socrates questioned would abandon their aspirations and create schools to teach and spread the ideology of philosophy. Plato, his most famous student, became the teacher of Aristotle, and he became the tutor for Alexander the Great. Socrates mentality of Greek philosophy would be spread throughout the world during Alexander's conquering of nations.…
Imagine a world where everything is based upon keeping a made-up being happy, a world where humans believe this blindly because no one has decided to ask why. This is the exact world of Before Christ Greece. The “made-up beings” were best described by Homer and Hesiod and were called gods. The existence of the gods was not questioned by the greeks for many years. Nature philosophers came into being when they started asking why and tearing down the world brought on by Homer and Hesiod.…
William Herschel was an Englishman in the late 1700s who became very interested in astronomy and fascinated at the question that other life existed beyond Earth. He began reading novels on astronomy and even began making his own telescopes to begin observing the vast night sky. Motivated in his belief that life existed outside of Earth, Herschel began searching the heavens for clues of foreign new life. On March 13, 1781, Herschel noticed something he hadn’t before. Presuming it to be a comet, he recorded his discovery.…
Abstract: My research paper is covering the different theories covering the origins of life. Primordial Soup: The primordial soup theory says that life began in a lake or ocean as a combination of chemicals created amino acids, and from there life evolved. A Russian chemist named A.I. oprin and an English geneticist named J.B.S. Haldane came up with this theory in 1920. to test this theory they collected and mixed elements thought to be on earth at the time and sparked the mixture with electricity, The experiment resulted in the creation of amino acids.…
Greek Famous People Ancient Greece influenced the modern world in many ways. Ancient Greece had some of the best minds ever. A lot of the scientific information we know today came from ancient Greece like our solar system revolves around the Sun, and the Earth is round. There also was a great deal of philosophers from ancient Greece that continue to influence the world thousands of years after their death.…
Charles Darwin created the theory of evolution, and through his books, made it public. While on his five year voyage, Charles visited the Galapagos Islands and noticed how each island seemed to have its own exclusive species of finch that were different from the ones on the mainland. Through this and other observations, Charles concluded that living things are always changing to adapt to their environment. After about 23 years after his voyage Charles published The Origin of Species. There was much controversy about it.…
