Dysfunctional behaviors in natural selection

Post by shreddy23 » Tue Feb 23, 2010 10:52 pm

Many primitive people follow some food practices that are dysfunctional (like restricting protein intake during pregnancy). HOw can these behaviors be explained by natural selection

primitive peoples don't understand the concepts of protein,carb,fats or balanced diets.
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;

I don't know about that example or what kind of primitive people you're talking about but those food practices are probably the result of cultural traits, not natural selection. That would be a negative by-product of our brain's evolution, which probably provides those same primitive people with benefits that far outweigh those disadvantages and hence, seems perfectly explainable by natural selection.

Many people today in the middle east (which are arguably not primitive) will also adopt dysfunctional practices for their survival that consists of attaching explosives around their waists, so you don't need to look that far.
