A comment my daughter Michelle made on a Facebook thread recently got me thinking about the concept of evolution. She pointed out that evolution is nothing more than the natural outcome of a few basic principles of biology and that there is really nothing “theoretical” about it. She was stating that evolution is simply the result of the operation of those basic principles and to call it a “theory” is like speaking about a “theory” of square. Through the operation of a few basic principles of biology, on which we all should agree, evolution happens in the same way that following a few basic operations in geometry results in a square.
I am no biologist. In fact, although I have had a great affection for science my entire life, I was always least comfortable with biology. But I am hoping that that might give me an advantage in explaining evolution as a true layman.
