Speech Summary: The history of our world in 18 minutes — David Christian

From The Big History Project, Khan Academy
  1. The Big Bang (only hydrogen & helium)
  2. Stars light up (Gravity)
  3. New chemicals get created when a star dies (new atoms)
  4. Solid planets and moon
  5. Living organism
    When molecules get combined to a point that they are too big to keep in the same shape. A new trick gets introduced. “You don’t stabilize the individual; you stabilize the template, the thing that carries information, and you allow the template to copy itself. DNA, of course, is the beautiful molecule that contains that.” “The real beauty of DNA though is in its imperfection.” “As it copies itself, once in every billion rungs, there tends to be an error. What that means is that DNA is learning. It’s accumulating new ways of making living organisms because some of those errors work. So DNA’s learning and it’s building greater diversity and greater complexity.”
Red mean the error (From TED Talks, 11:00)
Humans learn things faster (From TED Talks, 13:27)
