Obviously you seem to be very proud to go to college. That's fine. College is great and to study evolution in detail. I agree with you that most people don't understand evolution correctly. Maybe I also don't understand it correctly. That's why I am reading books and scientific articles to at least understand it basically.
Even scientists and your textbook writers don't understand all mechanisms how species adapt to their environment. But they do. DNA and genes are affected even by experiences a creature has. Even your genes might be affected by the experiences your grandfather had.
Inform yourself about "Epigenetics."
And a word to you.
Why are you so dogmatic? We have to cope from the effects of a dogmatic religion. Be open for other views and respectful. There is no need to brag about your college education.
And by the way. In 10 years your 'holy' textbook might be outdated.
