Pfffftttt!<quoted text>Hereditary changes in a population over many generations, Glad I could help with your education. Let me know if there is anything else I can clear up for you.
That is incorrect.
That is not evolution. Hereditary changes occur over generations without evolution.
In fact, there is absolutely no way to avoid it.
If that were the correct answer, there would be no controversy anywhere about evolution.
The Pope, James Dobson, and Jerry Falwell would agree with your definition.
To you, it is the most important FACT in all of history - AND YOU CAN'T EVEN SAY WHAT IT IS!
