Might I add, "This skull has a life expectancy of 35."
I appreciate the idea behind the diet (less refined foods in general seems to be a great start), but life expectancy started to expand and life became "better" once agriculture developed. That means more whole grains and some dairy products.
And unless Dr. Cordain knows something that the rest of us missed out on, Paleolithic man was a "mammal", which means he recieved his food from the mammary gland of his mother during his very early life. So that skull indeed did drink milk.
I hear a lot of people say that college diplomas are no indication of intellect, but whoever came up with this diet as historical went ahead and proved it.
