Sunflowers and Evolution

I'm reading a book on evolution by Richard Dawkins. It's very interesting. Did you know, for example, that sunflowers were genetically engineered by Russians to have flowers that are huge? That's because the Orthodox Church banned the use of oil in cooking during Lent and Advent, and somehow, sunflower oil was deemed to be exempt from that religious prohibition.

Richard Dawkins comments: "Perhaps because -- being a New World flower -- the sunflower is not mentioned in the Bible. The theological mind takes a delight in the intricacies of dietary law and the ingenuity required to dodge them...French Catholic gourmets discovered a loophole that enabled them to eat meat on Fridays. Lower a leg of lamb into a well and then 'fish' it out. They must think God is awfully easily fooled."
