The Evolutionary Biology of Scrunching Foreheads

The Evolutionary Biology of Scrunching Foreheads

I was watching Gladiator the other night and realized Russell Crowe is always scrunching his forehead. I was suddenly reminded of all the celebrities I know of that scrunch their foreheads as part of their image. That’s when I began wondering if scrunching your forehead was a thing.

Turns out, it is.

According to evolutionary biology, one of the main reasons modern humans are unique from pre-modern humans is because of our extended forehead.

Early humans (over 500,000 years ago) had short brows that communicated dominance.

Modern humans have expansive foreheads with subtle muscles to communicate emotions.

The theory is that as we evolved to become social creatures, our displays of empathy were more important / attractive than our displays of dominance & aggression.

Scrunching your forehead communicates you’re sensitive.
