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.
Early humans (over 500,000 years ago) had short brows that communicated dominance.
Modern humans have expansive foreheads with subtle muscles to communicate emotions.
