    I’m interested in the idea of selection adaptation and motorised vehicles, however I think selective adaptation takes much much much longer than motorised vehicles have been with us so far. We’re talking hundreds of years for selective adaptation to take affairs.

    I could be wrong about that though.

    The more likely adaptation reason currently is that we like over eating. Food used to be scarce, and when it was available you ate as much as you could or you died. The survivors of that scenario are the ones that made us, and as such we love eating lots when it’s there.

    I think our fascination with sweet foods makes sense from this perspective also. Our ancestors exposure to sweet foods were mostly fruit. Fruit would have improved their immune system significantly. Unfortunately we’ve since began mass producing sugar which doesn’t offer the same benefits, but our bodies are still set up to love that sweet taste.

    I’m rambling a bit, but there you go.

      car accidents are one of the largest causes of death of people below the age of 35 in the US if I recall. This means its likely one of the largest selection factors for people at or below reproductive age.
