I've noticed many people who disagree with evolution theories (and some who do agree with them) seem to completely misunderstand what biological evolution is.

Please summarize the Theory of Evolution as you understand it in a basic statement, keeping in mind you don't have to agree with a theory to understand what it says... but you do have to understand a theory before you can make an intelligent choice about it.

I'm doing a research project to see if their's a direct correlation between sunspots, earthquakes and tropical cyclones and I have found one. I want to know if sunspots affect earth's magnetic fields. Which would trigger earthquakes and somehow trigger tropical cyclones.

So many people think the Earth is a Sphere. But it is flat, like a page in a book. Even the Bible says the earth is round.
