Crux of Moore’s Law and the Origin of Life by The Physics arXiv Blog:

  • The complexity of the genome seems to grow exponentially.
  • Extrapolating back to the past, it is possible to estimate the time when this complexity was 0 – a single base pair.
  • The time of 0 genome complexity is estimated at about 10 billion years ago.
  • Since the earth is only 4.5 billion years old, it could be that bacterial spores from elsewhere arrived at the young earth.
