John on PETA, Atkins, and Evolution
John on Dean Esmay's blog writes about evolution and vegetarians.#
Agriculture and its concomitant boost in the food supply led to a lot of sweeping changes in the way humans developed as individuals. A better food supply means that people live longer, children have a better chance of surviving in to adulthood, and those same children can probably have more children with a better chance that they will survive as well. This isn't anything new in the way of theorizing, by the way, and it's all pretty general, but then so is evolution.
So for ten thousand years or so humans have been living within a food supply system that is unlike anything they have experienced previously. We eat tons of carbohydrates and processed sugars that simply were not a part of the diet as we evolved. The result is that a new evolutionary pressure is being placed on Man- we are slowly sorting out the species on the basis of who can easily handle a high carbohydrate diet, and who cannot.
In The Third Chimpanzee (link to my notes), Jared Diamond writes about how this isn't entirely true. Before agriculture, humans had small and very healthy tribes where they could live -- but afterwards they had very large and not as healthy tribes. Read about how Native Americans started to get terrible teeth and bones and start to have higher and higher infant mortality rates when they started to grow and consume corn.
The other comments John makes are very interesting... the idea seems to be that vegetarians are doomed to extinction because they are purposely going against evolution and not using all the resources available to them.
No population in a closed environment can expand forever and humans will eventually have to accept this somehow. Similarly, eventually the environment will be completely destroyed and we'll have to accept that as well. And there is also the concern that is an unethical life worth living?
I have only questions, no answers.
