Biological-complexity Quote by Lee Spetner
““Common sense says that the amazing complexity of life cannot arise out of a random process. The neo-Darwinians use clever arguments to show why evolution should work and why common sense is wrong. One after the other of them has explained that although the variability occurs randomly, the selection process gives it direction and makes it nonrandom. . . . if the arguments were solid and correct they should have put the theory on a stable and reliable foundation. The neo-Darwinians would like everyone to believe they have done that.””

Source Book: The Mystery of Life's Origin, Lee Spetner, 2005
The quote argues that random variation plus natural selection can produce complex life, challenging the claim that common sense disproves evolution.
In simple terms: Evolution uses random variation and nonrandom selection to create complexity.
Recognize selection’s role in shaping life.
