I know. The evos love to say how "solid" a scientific "theory" really is and us do-dos just don't understand. Comparing the "theory" of gravity to evolution is ludicrous. Drop an apple and you'll see gravity in action. Gravity itself is not a theory but an observable reality. Exactly how gravity works is open to theory. Evolution, on the other hand, specifically MACRO-evolution IS a theory. We can not observe this type in action, as we can gravity. Of course, the evos demand evolution is fact and that there are few unanswered questions. This article proves otherwise. It shows that while the evos firmly believe in evolution, HOW we got from point A to point B is NOT firm. Evolution is but change. Incest is prohibited because observably changes can occur. Engaging in interbreeding or incest and having the offspring arrive with six fingers is a observable reality.
