Notes

FYI:

• In 1000 years you have had 1 billion ancestors.  -- 2 to the power of 30.  ...But only 1 Y nucleotide; a large chromosome with 10,000 positions.
  
• The 'magnetic pole' of the earth is caused by the rotation of the liquid iron inside the earth.  -- If that iron was solid, then there would be no 'magnetic pole'. 
• All of earth's water was brought to earth via icy meteors.  This water was created by the explosion of dieing suns (the only time when Hydrogen fuses with Oxygen).
