Evolution Is A Fact, And A Theory

Neat post explaining the difference between theory and fact, and how evolution is both. Creationism, by the way, is neither.

Biologists consider the existence of biological evolution to be a fact. It can be demonstrated today and the historical evidence for its occurrence in the past is overwhelming. However, biologists readily admit that they are less certain of the exact mechanism of evolution; there are several theories of the mechanisms of evolution.
I think this would be a better country, and a better world, if people would stop clinging to manifestly false beliefs about how the world works. If religion brings comfort, a guide for personal development, a sense of belonging and tradition, I can live with that. But when religion makes manifestly false claims about the operational realites of life on this planet, it becomes an anchor holding back the development of human civilization. As someone (Galileo?) once said, and I paraphrase, I cannot believe that God would give us the power of reason and then compel us not to use it.

  1. Right. It's a fact that evolution has happened and is happening now, and it's a theory that evolution is the mechanism that brought us from single-celled organisms to the terribly impressive creatures we are today.
