L1: ORIGIN OF BIODIVERSITY BIOLOGY

Cards (15)

  • OSCILLATING THEORY
    • Pulsating Universe Theory
    • Proposed by ALEXANDER FRIEDMAN
    • The universe was believed to CONSTANTLY EXPANDING but time will come that will CONSTRICT THEN EXPAND AGAIN to continue the NEVER ENDING CYCLE.
  • Bing Bang Singularity
    • Smaller than atom
    • Superforce
  • STEADY STATE THEORY
    • Proposed by FRED HOYLE, HERMANN BONDI and THOMAS GOLD
    • As the universe expands, it CREATES THE EXACT VOLUME THAT WAS MOVED OR USED DURING EXPANSION TO FILL UP THE SPACE thus the universe has no beginning nor an end
  • BIG BANG THEORY
    • Universe starts in a "POINT OF SINGULARITY"
    • It NEVER STARTED in a bang or explosion but rather the SINGULARITY EXPANDS overtime
    • Proposed by GEORGE LEMAITRE
  • BIBLE BASED THEORY: SPECIAL CREATION THEORY
    • Life begins with God, life was created by God
    • The earth was created in 6 days, on the 7th day, the Lord rest (Sabbath)
    • Genesis 1:1-31; 2:1-4
  • Inflation forms photons
  • SCIENTIFIC BASED THEORY: THEORY OF SPONTANEOUS CREATION
    • proposed by Aristotle
    • Life came from non living things or spontaneous event
    • Progressive development from non living things
    • Proven wrong by Lazaro Spallanzani, Francesco Redi and Louis Pasteur
  • SCIENTIFIC BASED THEORY:
    THEORY OF BIOGENESIS
    • OMNI VIVO EX VIVO - "All life is from life"
    • encompasses the belief that complex living things come only from other living things, by means of reproduction.
    • Primarily developed by Louis Pasteur, supported by Lazaro Spallanzani and Francisco Redi
  • ABIOGENESIS
    Life came from non living but not spontaneously
  • BIOGENESIS
    Life came from life
  • SCIENTIFIC BASED THEORY: ABIOGENESIS THEORY
    • Alexander Ivanovich Oparin (1924): "Primordial soup" theory written on his book "Origin of Life"
    • John Burdon Sanderson Haldane or JBS Haldane (1929): "Life came out of chemical evolution"
    • The theory is also known as Oparin - Haldane Hypothesis.
  • Stanley ​Miller - Harold Uray experiments proved Oparin- Haldane Theory
  • Primordial soup is an aqueous solution of organic compounds that accumulated in primitive bodies of water of the early Earth as a result of endogenous abiotic syntheses and from which some have assumed that the first living systems evolved
  • Primitive atmosphere is primarily made of CH 4' H_{2} H_{2}*O N_{2} and N*H_{3} It only lacks OXYGEN
  • 8 Characteristics of Life
    Adaptation through evolution
    Cellular organization
    Growth and development
    Heredity
    Homeostasis
    Metabolism
    Reproduction
    Response to stimuli
