Survival of the Fittest
“Strong people are harder to kill than weak people, and more useful in general.”
- Mark Rippetoe
The phrase “survival of the fittest” refers to the process of natural selection - the members of a species best suited to survival in their environment are more likely to live long enough to reproduce and pass along their genes, with each successive generation becoming better suited - more fit - to survive in that environment. Having already been born, there is little we can do to improve our fitness in the genetic/evolutionary sense. That is decided for us at the moment of conception. However, we can and should do everything we can to improve every aspect of our fitness in the physical sense.
In most parts of the world natural selection no longer operates the way it does in the wild due to agricultural and medical advancements and cultural and societal changes. These changes have lowered the genetic bar for survival significantly - have almost gotten rid of the bar altogether. Advancements in labor saving devices and easy access to calorie dense food have compounded this by minimizing the physical effort required for daily survival to practically nothing, resulting in a society that is mostly weak, slow and fat. Most people alive now in developed countries would be incapable of handling the physical demands of the day to day lives of our ancestors, and would have no hope of surviving in such an environment. There would, however, be far fewer hungry bears and lions. › Continue reading
