Tony: Now, correct me if I am wrong, but isn't this the exact opposite of what we would expect from evolution? Evolution via NS and survival of the fittest says that these types of problems would be weeded out over time.-The point is, probably not enough time to make changes. We Westerners have only become different fully in life style from hunter-gatherers over the last 4-6,000 years. Agriculture is only 10,000 years old.- An example of change, lactose tolerance. 85% of Africans cannot handle milk (Massai excluded). Homo s. left Africa 30-50,000 years ago, and most laplanders can handle milk easily. They had reindeer herds, drank the milk and adapted with the right enzyme, lactase. Mediterranean Europeans are 50/50 tolerant, etc.-> 
> Tony:That is what this sounds like to me. You have a hydraulic pump that needs a certain amount of internal pressure, but not to much, in order to function at max efficiency and have fluid regulator whos job it is to try and compensate for fluctuations in those levels. Deterioration in the pump triggers the fluid regulator to start trying to perform its function, but the pump is already damaged at that point and tries to use its own fail safes at the wrong time.

> This sounds more like devolution than evolution.-Not devolution, just a persistence of old evolutionary solutions that do not fit today's health problems, and God hasn't dabbled to fix things in the short time involved. And this is so fixed in the way the body works, I doubt humans can continue their current Western lifestyles and get the heart and kidney to adapt to a different solution. This is not the simple finding of a digestive enzyme that is generally lost after nursing. That is a simple re-adaptation, since the mechanism had been present in early life. -This discussion tells me evolution happened, but still presents me with the pre-planning/dabbling issue.
