Here's an example of evolution. Bacteria populations developing resistance to antibiotics. No, they did not turn into salt water fish....
That’s natural selection, or probably more accurately...selective breeding, which no one denies.
Natural selection IS A KEY COMPONENT OF EVOLUTION! If adaptation is successful across tens of thousands of generations, it becomes evolution; because adaptation never stops. Its a mathematical constant...eventually you'll get to another species...or the species will die off. If you accept adaptation, you have to accept evolution because it's a mathematical certainty over time.
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
