Evolution in Action?

I hadn't heard this before, but the shape of the human skull has changed in the recent past, measured from the present day back 650 years.

Researchers have found that the shape of the human skull has changed significantly over the past 650 years.

Modern people possess less prominent features but higher foreheads than our medieval ancestors.

Writing in the British Dental Journal, the team took careful measurements of groups of skulls spanning across 30 generations.

The scientists said the differences between past and present skull shapes were "striking". . .

The two principal differences discovered were that our ancestors had more prominent features, but their cranial vault -- the distance measured from the eyes to the top of the skull -- was smaller.

Are we smarter on average now, compared to 650 years ago? I would bet not.
