I never said it was the only straw, but I believe it is the largest
factor by far. If anyone can show me a shred of evidence that humans
have made some dramatic change in genetic composition in the last 3-4
decads, I'll admit that I'm wrong.


Matt, I don't think it has happened in the last 3-4 decades. I don't
think it is a change in genetic composition but a survival of that
genetic composition in the last 300 years.

When food is scarce, those who's body can utilize whatever food is
available will survive. In the livestock industry, such an animal is
known as an easy keeper. It is a trait of some species and some
breeds.

Example: Several studies of Navajo, Pima and Apache Native Americans
have revealed between 45 and 74 percent have type 2 diabetes. A
condition brought on by obesity. The prevalence for obesity was a
result of culling those ancestors who were not "easy keepers" in
difficult times.

Bottom line is the abundance of food for those with "easy keeper"
genetic composition.
