Seppo Down Under

Obese or Darwinian Superiority?

I was getting into the shower the other morning and there was a spider hanging out in a web right in the middle of the tub. Spiders work fast over here, and if there is a "prime" location to spin a web, believe they will in the Goldfields. So being the nature lover that I am, I figure I'll just hit the water and let him/her figure out where to run to keep from being washed down the drain. It's not in my place to take the spider's life, as it could be the one that eats the mosquito that would have given me malaria...or at least a really itchy bump. So he piddles around a bit and finally skitters to a dry location under the soap holder. I figure that's a good location, but then the little rascal crawls out of there and up the wall a bit. Why not stay in the protected location in trade for one out in the open? At that point I figure that spider would learn a bit of sense after it evolves a bit over a few generations in the same environment. I then began thinking about evolution of a species...not the whole man from protazoa or man from monkey crap, but the evolution of a species to adapt to it's specific environment. I then came to the conclusion that animals with a short life span have an advantage when it comes to physical adaptation, as they have more regular modification of adaptive genetic qualities.

How does this apply to man? Outside of the initial skin colour changes ocurring after the mass exodus of modern man out of African 30,000 years ago, man has mostly adapted through inginuity, not physicality....until now. Let's think about this for a minute. "Global warming" or the more politically-correct "climate change" is supposed to dump the Earth into another great ice age (even though the Earth is technically in an ice age since the polar caps are still frozen). What if the obesity "epidemic" is just a genetic adaptation to the upcoming ice age. Fat parents have passed on the genetic potential to be fat onto their children. Insulin resistance, the supposed "fat gene" that controls lipolysis, high 5a reductase levels, and low thyroid levels all give the kid a higher chance of being obese. If that wasn't bad enough, not too many fat parents feed their children salads and tofu. Here honey, have a burger! So when the climate makes this huge swing, all of us fit and skinny people will be at a disadvantage.

I'm a fitness nut with an athletic build, but what if obesity is some ancient genetic coding taking over to evolve humans into a cold-resistant species?
