The argument we had no need for it does not prove it wasn’t around anyhow. Likewise the argument that this is the way it works in other mammals proves nothing. Humans, <I>unlike</I> almost all other mammals, cannot manufacture vitamin C (an essential nutrient for life). If we were like other mammals in this regard, our bodies would produce it.<BR/><BR/>Besides, in order for natural selection in favor a genetic expression, it must confer some survival advantage. While milk as an adult food source may have added to food availability, it is unlikely to have added a survival advantage to anyone because if milk was available as a food option, then other food sources would have been plentiful too (if livestock isn’t well nourished, they’ll dry up, so the presence of a milk supply implies conditions favorable to other food sources as well). Milk as a food choice, therefore, would confer no added survival advantage.<BR/><BR/>Although the dairy industry would like us to believe otherwise, milk is hardly a health food for non-infants. So it has little to offer in terms of additional nutrition, which might have conferred a survival advantage.Anonymousnoreply@blogger.com
