Simply can't be answered from a historical viewpoint if you are an evolutionist, however, the Biblical record has several references to cheese milk and cheese.
Job 10:10 "Did You not pour me out like milk And curdle me like cheese;
2 Samuel 17:29 And honey, and butter, and sheep, and cheese of kine, for David, and for the people that were with him, to eat: for they said, The people is hungry, and weary, and thirsty, in the wilderness.
However, I grew up on a farm and in my early post high school years worked in an occupation linked to genetics in the dairy industry. The modern day dairy cow is nothing like it was even 50 years ago. They've been bred for greater production, fat, protein etc. Some (not all) farmers use bovine growth hormone, feed cattle soy (much of which these days is genetically modified and or sprayed with chemicals) Truthfully, when drinking milk, I'd make sure I pick from those that don't contain bovine growth hormone and if possible drink only certified organic. I also don't believe that raw milk is harmful. Grew up on the stuff, so if you can find a good raw source from an organic farm and they aren't getting in trouble passing some along, then by all means go for it. I think moderation is the key as long as you aren't allergic to it or something.
My husband can't drink milk or eat a huge amount of cheese. He gets terrible sinus infections. For him it's out of the question. I'm not bothered by it at all.
To make a certain writer your guru, god, authority or whatever is not always the best decision. Do the research, decide what works best for you. No caveman carved it in stone.
