La cabeza humana se está haciendo más pequeña, eso de acuerdo a unos científicos que han estado haciendo investigaciones al respecto. Segun ellos hace 10,000 años la cabeza de nuestros ancestros era 30% más grande.

Changes in diet are thought to be the main cause. The switch to softer, farmed foods means that jawbones, teeth, skulls and muscles do not need to be as strong as in the past.

The shrinkage has been blamed for a surge in dental problems caused by crooked or overlapping teeth.

“Over the past 10,000 years there has been a trend toward rounder skulls with smaller faces and jaws,” said Clark Spencer Larsen, professor of anthropology at Ohio State University.
