Interesting article on The BBC news webpages about some research that shows that the human skull has changed quite significantly and quite remarkably obver the last 500 years.... and if you wander around Cambridge you can see loads upon loads of examples of the 'new headshape'.... you know how the stereotypical image of a scientist always possesses an enormously domed forehead...you know the one... ok this is known as the 'cranial vault height' which is the distance between the eyes and the top of the head.... this height has increased somewhere in the order of 20% since Medieval times... and the researcher suggests the increase in size may be due to an increase in mental capacity over the ages.... and one can only therefore deduce after that, that the cartoon image of the scientist with the large forehead is based on scientific fact....
