I am talking about traits that are not detrimental do not get selected against by natural selection. This means that we (and other animals) retain traits that do not directly afford a survival advantage. So you and 17th century sailors find earlobes useful but you would be hard pressed to show evidence that it provides a selective advantage. I'd be willing to go out on a limb an say that primitive men without earlobes would have been just as competitive as their earlobed cousins. That is to say, show me the data on this earlobe theory of yours. Show me the data in a peer-reviewed scientific journal and I may be convinced. We can live without gal bladders, appendixes, hair, etc. but we still have them. Spirituality may be the same way. Just open your mind a bit.
