Introduction to Evolution : Introduction to Evolution Slide 2: Evolutionary theories have come to replace the Bible as the most scientific in explaining existence. The problem with the Bible is that it demands faith. Mixing faith and science is thought to be bad science. “Now faith is being sure of what we hope for and certain of what we do not see.” – Hebrews 11:1 Wherever faith is mixed with science in my discussion, I will put this symbol. “ A fair result can be obtained only by fully stating and balancing the facts and arguments on both sides.” – Charles Darwin, The Origin of Species, p. 66 : “ A fair result can be obtained only by fully stating and balancing the facts and arguments on both sides.” – Charles Darwin, The Origin of Species, p. 66 Darwin’s Environment(Darwin, 1859, p. 53-69) : Darwin’s Environment(Darwin, 1859, p. 53-69) Natural Science was the outer frontier of knowledge. Previously, scientists had postulated evolution, but had not discovered a sufficient mechanism. The reigning fundamentalist doctrine declared that there was no modification within species, an obvious shortcoming perceived by the scientists of the day. Darwin’s Environment : Darwin’s Environment There was common debate among scientists on what constituted a species vs a mere variety of a species. Genes were unknown. Darwin’s Day to Present : Darwin’s Day to Present The Reigning Doctrine has swung from a general acceptance of the Bible to acceptance of Evolution as an explanation of the world as we know it. Christians have coped with this state of affairs in several ways. Embracing a non literal interpretation of the Bible Rejecting Science Embracing the doctrine of Nonoverlapping Magisteria (realms of knowledge) or “NOMA” Creationism NOMA(Gould, 1997) : NOMA(Gould, 1997) Clarified by Pope John Paul II to the Pontifical Academy of Sciences on October 22, 1996 Declares that “truth cannot contradict truth” Basically, faith applies to spiritual matters, and science applies to physical matters with no contradictions. A Philosophical Exploration of NOMA : A Philosophical Exploration of NOMA PROOF 1 Science is our interpretation of the world we observe around us. Scientific progress depends on the assumption that interpretations (theories) may be modified, but observations (facts) are concrete. If evolution is true, then the evolved abilities of our minds and bodies to observe the world do not lead us to truth, but to survival. Therefore, facts are not concrete. A Philosophical Exploration of NOMA : A Philosophical Exploration of NOMA PROOF 2 If Evolution is true, then God did not create the world. Belief in creation is merely a beneficial adaptation having nothing to do with the truth. But then every generally held belief may merely be a beneficial adaptation having nothing to do with truth. This includes evolution. A Philosophical Exploration of NOMA : A Philosophical Exploration of NOMA Evolution makes knowing truth impossible. Innate in the practice of science is faith that Man is able to discover truth. Only belief in creation of man by God supports this. In the Name of Evolution : In the Name of Evolution “The undeniably feeble-minded should, indeed, not only be discouraged but prevented from propagating their kind.” – Margaret Sanger, founder of Planned Parenthood Slide 12: “It [The Government] must declare unfit for propagation all who are in any way visibly sick or who have inherited a disease and therefore pass it on…" – Adolf Hitler Slide 13: “…[The Origin of Species] contains the basis in natural history for our views…”—Karl Marx Slide 14: In 1906 an African pygmy named Ota Benga was kept on display in the monkey house at the Bronx Zoo as an example of a lesser evolved humanoid (Bergman, 1993). Evolution—A Quick Sketch(PBS online, n.d.) : Evolution—A Quick Sketch(PBS online, n.d.) 13.7 billion years ago, the Big Bang disperses matter across the universe. Through gravity, matter clumps together to form galaxies, solar systems, stars, and planets. 5 billion years ago, our Solar system forms. 3.8 billion years ago Atmosphere forms on planet earth as it cools Unknown forces cause first microorganisms to form Evolution—A Quick Sketch : Evolution—A Quick Sketch 700 million years ago, flatworms, jellyfish and algae appear. 570 million years ago, creatures with hard shells appear. 200 million years ago, first mammals evolve from reptiles 65 million years ago, dinosaurs become extinct, perhaps from asteroid slamming into Mexico’s Yucatan Peninsula. The Evolution of Man(Wikipedia, 2008) : The Evolution of Man(Wikipedia, 2008) 13 million years ago, Pierolapithecus catalaunicus appears. It is an early ancestor of modern man and great apes. 7 million years ago, Sahelanthropus tchadensis (Toumai Man) appears. It is the ancestor of modern man and chimpanzees. 6 Million Years ago, Orrorin tugenensis (Millenium Man) appears. It is the first ancestor of modern man post dating the separation from the chimpanzee line. The Evolution of Man : The Evolution of Man 4.4 million years ago, Ardipithecus ramidus appears. 3.7 million years ago, Australopithecus afarensis (Lucy) leaves bipedal footprints in volcanic ash. 3.5 million years ago, Kenyanthropus platyops appears. 2.5 million years ago, the ice age begins. The Evolution of Man : The Evolution of Man 1.8 million years ago, Homo erectus appears. Homo erectus migrates from Africa to Eurasia. 700,000 years ago, Homo antecessor appears—the last common ancestor of modern man and Neanderthal. 355,000 years ago, Homo heidelbergensis left footprints in volcanic ash. The Evolution of Man : The Evolution of Man 195,000 years ago, Homo sapiens appears. 110,000 years ago, the last glacial period begins. 60,000 years ago, Homo sapiens migrate out of Africa. 50,000 years ago, Homo sapiens migrate to South Asia. Modern behavior and speech appear. 40,000 years ago, Cro-Magnon migrates to Europe and Australia. The Evolution of Man : The Evolution of Man 25,000 years ago, Neanderthals become extinct. 12,500 years ago, the last glacial period ends. 12,000 years ago, the stone age begins, including domestication of animals, farming, pottery and cities. 5,300 years ago, the bronze age begins. 3,200 years ago, the iron age begins. Evolution’s Underlying Assumptions : Evolution’s Underlying Assumptions The present universe arose from nothing via natural processes, chance and long periods of time. The Big Bang accounts for a random dispersion of matter across the universe. Galaxies, Stars and planets form when clouds of gas condense under their own gravity. The Oort Cloud is the source of long period comets. Evolution’s Underlying Assumptions : Evolution’s Underlying Assumptions The first cell arose from chemicals on the early earth through unknown natural processes. All life evolved from the first cell. The dinosaurs became extinct 65 million years ago, long before the advent of man. Life today is best suited to today’s environment. Fossils take long periods of time to form. Evolution’s Underlying Assumptions Summary : Evolution’s Underlying Assumptions Summary The flood account in the bible is either a myth or describes a local flood. Geologic strata represent past ages in earths history. The fossil record shows a progression of links in the evolutionary chain, with primitive life forms in deeper strata and more advanced forms in higher strata. Mutations in genes allow for the increasing complexity in life forms over time. Assumes uniformity of natural processes throughout earths history vs. cataclysmic change, allowing dating techniques. Civilization has progressed from a primitive hunter gatherer society. 6 Kinds of Evolution : 6 Kinds of Evolution Cosmic Evolution—the universe arose from the Big Bang Stellar Evolution—Stars arose from the residual energy of the big bang Chemical Evolution—all the elements arose from hydrogen and helium Organic Evolution—living things arose from non living things Macroevolution—Change from one kind of creature to another over time. Microevolution—Change within a kind over time. Evolution in a Nutshell : Evolution in a Nutshell Slide 27: Basic Evolution (Riddle, Can)
