    Scientist Who Co-Discovered the DNA Says Our Genes Were Brought Here by Aliens Francis Crick (8 June 1916 — 28 July 2004) was an English scientist who was most noted for being a co-discoverer of the structure of the DNA molecule in 1953 alongside James D. Watson. Francis Crick Watson and Maurice Wilkins were jointly awarded the 1962 Nobel Prize for Physiology for Medicine “for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in

  • Panspermia And The Demise Of Humanity

    “Panspermia is a Greek word that translates literally as "seeds everywhere" (Panspermia-Theory.com) Panspermia theory is that “seeds” of life exist throughout the universe, propagated via cosmic scale expansion and explosions. “More mechanisms for panspermia include the deflection of interstellar dust by solar radiation pressure and extremophile microorganisms traveling through space within an asteroid, meteorite or comet.” (Panspermia-Theory.com) These seeds can be

  • Abiotic Synthesis And The Deep Sea Vent Hypotheses

    1305 Words  | 6 Pages

    Although both abiotic synthesis and the deep-sea vent hypotheses argue the environment of a primordial-Earth was required for the origin of life, the two hypotheses have their differences. In general, the abiotic synthesis hypothesis describes the process of how organic compounds can be created from inorganic compounds, while the deep-sea vent hypothesis argues a possible scenario where life may have originated from inorganic compounds. While the term “primordial soup” has been used to describe abiotic

  • The Miller-Urey Synthesis Essay: The Origin Of Life

    Evidence for this theory is also relatively strong as tests done on the Murchison meteorite which fell near Murchison, Australia in 1969 revealed it contained over 90 different amino acids (among which nineteen are found in Earth life). Although Panspermia does not directly explain the origin of all life (only its distribution) the synthesis of microorganisms in space could also be justified. If certain compounds were subjected to conditions similar to those of the Miller-Urey experiment, ultraviolet

  • An Exploration of Different Theories of Evolution Essay

    3317 Words  | 14 Pages

    An Exploration of Different Theories of Evolution Where did we come from? It is a question that has haunted the entire history of humanity. Thousands of years ago, our ancestors sought to answer the question with myths. Today, we are still struggling with the same question—only today we seek to answer this mystery with science. Given various observations, it seems plausible that all life arose from a few very simple organisms millions of years ago. Observations of life will raise

  • Primordial Soup Theory

    The theory that suggest that in some bodys of water is where life began is primordial soup theory. Because the chemicals combined from the atmosphere also with the energy to make amino acids which basically what proteins are built of. After the species would evolve.This theory was presented in 1920 by a chemist named A.I Oparin and an English Geneticist J.B.S. Haldane. While mixing gas that they were believed to be there on the first earth: Methane, Ammonia,water, hydrogen, no oxygen. Chemist Stanley

    500 B.C. He stated, “the intentional transfer of life to other planets by intelligent life.” Then in 1973, the Nobel peace prize was given to a British biologist, physicist and neuroscience professor, Francis Crick proposed the theory of direct panspermia. The claim is that the seed of life is everywhere and life existed all over the universe. The evidence that was found was a meteorite that landed in Antarctica had contained structures that were remains of terrestrial Nano

  • Essay on Popular Theories of the Origns of Life on Earth

    852 Words  | 4 Pages

    Life began in the Ocean The Big Bang theory is currently the most prevailing theory that explains the formation of Earth roughly 13 billion years ago. Substantial scientific research and theories are in agreement that when Earth was born, conditions on Earth was harsh. Due to nuclear fusion, Earth was very hot. One theory suggest that the heat of Earth evaporates the water which forms clouds and subsequently leads to rain. As Earth cooled, gravity traps the water collected and oceans started to form

  • The Origin Of Life : Intelligent Design Vs. Materialistic Naturalism

    2359 Words  | 10 Pages

    Marquel Gray Prof. Heather Clark 7/22/13 Eng.111-60A The origin of life: Intelligent Design vs. materialistic naturalism The origin of life has been questioned by men for thousands of years. Scientist have studied the universe extensively and developed various theories to answer questions related to the origin of life. Questions like, how did life begin? Is the universe the result of chaotic chance or intelligent design? How did life on earth come to be? These are some of the many questions

  • Primordial Soup Hypothesis

    here are many different theries presented by very hard working, and deticated scientists relating to biomolecules. This paper is about all the different hypotheses, and how these scientists back them up. There are six hypotheses that I will explain... The first, is the Primordial Soup Hypothesis. It was developed by a russian chemist named A.I. Oparin, and he was helped by some one named J.B.S Haldane. In 1924, Oparin put forward his theory that life on earth developed through gradual chemical
