Does natural selection prove evolution?

Did another speech at Toastmasters yesterday.  Essentially, the discussion boils down to:

Definition of natural selection (aka micro evolution)

  • The process whereby organisms better adapted to their environment tend to survive and produce more offspring.
  • Often referred to as “survival of the fittest”
  • Involves the death of those less suited i.e. the weak

Definition of (macro) evolution

  • The process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.
  • Takes millions of years.
  • Note the direction: from simple to complex.

Arguments for:

  • The theory of Natural Selection was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution (argument from authority).
  • It elegantly explains the origins of life on earth, without having to rely upon the direct intervention of a Divine being, which is unobservable, and thus unscientific.
  • Natural Selection is observable: we see extinctions happening all the time.

Arguments against:

  • Natural selection always results in a loss of genetic information, never an increase (theory of irreducible complexity).
  • It doesn’t matter how many times your ancestors cut off their right arms, your descendants will always be born with a right arm. (Acquired characteristics are not inheritable.)
  • Thousands of years of observable decrease in genetic information is not the same thing as millions of years of unobserved genetic increase. (Bait-and-switch argument.)

Conclusion:

  • Belief in evolution via natural selection is a desperate, non-scientific attempt to remain free of accountability to the divine Creator, despite logic.
  • The only alternative to evolution is direct creationism. The Bible does not support any other interpretation.
  • Evolution vs Creation is not Science Vs Religion but it is Faith Vs Faith

One thought on “Does natural selection prove evolution?”

  1. A beautifully clear and concise summary. Incredible how many ‘scholars’ cant understand it – or more accurately dont WANT to understand it!
    Thanks.
