It is the things we think we know - because they are so elementary or because they surround us - that often present the greatest difficulties when we are actually challenged to explain them.

God was there when it happened. We were not there.... Therefore, we are completely limited to what God has seen fit to tell us, and this information is in His written Word.

The proof of evolution lies in those adaptations that arise from improbable foundations.

All organisms vary, and it's just folk knowledge. You just have to look around a room of people, and everybody knows that it's true. Darwin didn't know the mechanism of heredity, but you don't have to. You just need to know the fact of it.

When people learn no tools of judgment and merely follow their hopes, the seeds of political manipulation are sown.

The enemy of knowledge and science is irrationalism, not religion

I was lucky to wander into evolutionary theory, one of the most exciting and important of all scientific fields. I had never heard of it when I started at a rather tender age; I was simply awed by dinosaurs. I thought paleontologists spent their lives digging up bones and putting them together, never venturing beyond the momentous issue of what connects to what. Then I discovered evolutionary theory. Ever since then, the duality of natural history-richness in particularities and potential union in underlying explanation-has propelled me.
