Natural Selection May Cause Alzheimer's Disease Genetic Mutation To Die Out

In a world filled with natural disasters, war, and growing risk of incurable infections, one study is shining a little ray of hope that perhaps the future won't be as grim as we imagine. The study found subtle evidence to suggest that certain genetic diseases, such as Alzheimer's and asthma, may be weeded out by natural selection. Sure, it may take a few thousand years, but at least our future generations would have something to look forward to. Natural selection is nature's way to ensure life keeps on living despite drastic changes in environment and lifestyle. You may think that humans have reached their evolutionary peak, but the research found evidence that genetic variants that influence fertility in the U.S. and UK are slowly changing, and may be working to weed out certain mutations that lead to a number of serious health conditions, The Independent reported.
