From the BBC Science Report:
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.
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.
Dr Peter Rock, lead author of the study and director of orthodontistry at Birmingham University, told the BBC News website: "The astonishing finding is the increased cranial vault heights.
"The increase is very considerable. For example, the vault height of the plague skulls were 80mm, and the modern ones were 95mm - that's in the order of 20% bigger, which is really rather a lot."
He suggests that the increase in size may be due to an increase in mental capacity over the ages.
If that's the case, then Fred Elliot is a genius.
