  1. When did Charles Darwin write “On the Origin of Species?”
    1859
  2. Why did atheists appreciate Darwin’s book?
    It gave them a way to explain life without God
  3. At the time that Darwin wrote his book, what did scientists think about the smallest unit of life?
    It was a simple bit of protoplasm/jelly that somehow had a “spark” of life in it
  4. Who are molecular biologists?
    They study the incredibly complex molecules of life
  5. What have molecular biologists discovered about life?
    Each cell has trillions and even quadrillions of atoms with an incredibly high degree of organization forming incredibly complex interdependent molecules that are necessary for life
  6. What is a simple living cell really like?
    A miniature city in every cell
  7. How many atoms might there be in a simple living cell?
    Trillions or quadrillions
  8. How few proteins might a very simple, conceivable but not known, cell have?
    A few hundred
  9. What are proteins made of?
    Amino acids
  10. How many different kinds of proteins are there?
    Thousands
  11. How many atoms are in a typical protein?
    Tens of thousands
  12. Can these atoms just come together on their on to make a protein?  
    no
  13. What are Amino Acids?
    The building block molecules of proteins
  14. How many different kinds of amino acids are there?  
    20 (the 21st and 22nd amino acids have been identified, but are very rare)
  15. What can Amino Acids be compared to? (Amino Acids  are to proteins what ______ are to words)?
    letters
  16. How many different amino acids might there be in a typical protein?
    A few hundred to a few thousand
  17. How are protein molecules assembled?
    Long chains of amino acids are put together and then folded very precisely into 3-d shapes
  18. What is an RNA molecule? How many atoms in a typical RNA molecule?
    Huge molecules that carry information from a DNA molecule to the parts of the cell that assembles proteins. Tens of thousands.
  19. What is a DNA molecule? How many atoms in a typical DNA molecule?
    An incredibly long molecule that contains all the information required to produce and maintain all the incredibly complex parts of a living organism
  20. How long might a DNA molecule be if you stretched it out?
    6 feet
  21. How long might a DNA molecule be if you enlarged it to the diameter of your little finger?
    1000s of miles
  22. What does the DNA molecule do?
    Maintains all the information required to produce and maintain all the incredibly complex parts of a living organism
  23. Can a DNA molecule reproduce by itself?
    no
  24. What is true about the simplest self-reproducing unit imaginable that makes it very, very difficult  for honest skeptics to reject God?
    It is made up of unbelievably complex molecules that, if somehow they seemed to be “assembling” on their own, would all disintegrate and fall apart quickly
  25. Can scientists, with all their genius and all their elaborate scientific equipment, produce a unit from scratch that can reproduce itself?
    no … not even close
  26. What are two examples of interdependent molecules in a cell?
    Protein synthesis has to have a cell wall… but a cell wall cannot exist without protein synthesis. Translational systems depend on certain enzymes, but those enzymes cannot exist without the translational system
  27. What is the significance of interdependent molecules in a cell?
    They cannot “form” one at a time… they have to begin to exist all at the same time.
  28. What is good analogy to the possibility that all the parts of a reproducing unit might come together by sheer chance?
    A city suddenly appearing on a barren desert
  29. What famous law of physics makes it impossible for these parts to come together by chance over billions and billions of years?
    2nd Law of Thermodynamics
  30. Who was Francis Crick?
    Nobel prize winner… co-discoverer of DNA
  31. What did Francis Crick have to say about the origin of life?
    Seems like a miracle
  32. What illustration did Fred Hoyle use to show how absurd it would be to assume that life came about by chance?
    Tornado in a junkyard producing a boing 747 jet aircraft
  33. What does God say about His creation in Romans 1?
    The existence of a Creator is obvious and  evident to anyone who is willing to see
