Mutational Problem

Wouldn't the high rate of diabetes, heart disease, cancer be considered harmful mutations in the gene pool? These are certainly on the rise and are listed on most individuals past medical and family history forms when they come into the doctor's office as a new patient.Mixed race offspring is very common these days and I see that eventually with all of these genes being mixed together that the global population will consist of human mutts some day.The potential for equilibrium does not appear impossible when you see it from another perspective.

I know several individuals who exercise and are definitely not overweight but are diagnosed with Diabetes II. They have a family history of diabetes which makes me think that people are born with imperfect insulin genes that work in their younger years but as they age they become more damaged as in mutations.Individuals with family histories of different types of cancer affecting their Mother's, Father's, aunts, grandparents, etc tend to have a higher rate of getting some form of cancer in their 30's usually breast or colon cancer.This is either genetics or it is directly being caused from their environment.
