(Humans changed biologically, too, evolving such new traits as the ability to digest lactose as adults.)- Pollan, (p 320)
Wait a minute, milk has lactose, right? So, doesn't that mean that humanity also had to evolve to be able to handle some of the things that domesticated animals provided us? Well, that explains why some of us are allergic to cow's milk. I find that interesting. Now I wonder what other adjustments humans had to go through to accommodate the domesticated animals, just as they had done so for us.
In other news, the second half of "Omnivore's Dilemma" is very interesting compared to the "Conspiracy of Corn". This is actually about the evolution of the human omnivore, and the things we still face today that's left over due to our primal roots. Micheal Pollan decides to go on a journey of sorts through the old ways of the omnivore to present to his family. He is reluctant on this journey, but I can tell he's learned a lot in the experience. The most shocking of these discoveries is when he learns of his alter ego as the hunter.
Seriously, I'm wondering just about how much of human nature is what was developed "over time" and what has always been with us. I'm assuming the "killer's instinct" is one of the later, because all animals have it. But then this dips over into society, which has only been "recently" established as a "true science" compared to others, which has been philosophica.
Considering all the mental diseases and problems in the world, couldn't you help but wonder which among these are actually parts of human nature that we later deemed as "abnormal" as society developed? I admit, it would be funny to imagine a caveman with split personalities (clinically deemed "Dissociative Identity Disorder"), but maybe some of the forms of Psychosis have always existed to some extent. I'm thinking that the safe bet of mental conditions that have always existed is phobias. For some reason, this is making me pity those lactose intolerant cavemen who consistently feared the useful tool of fire.
