According to a story on BBC News the human cranium has undergone some interesting changes over the last 600-700 years:
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.”
The study included 30 skulls from the mid 14th century (plague victims), 54 skulls from the wreck of the Mary Rose (Henry VIII’s warship) from 1545 and 31 recent (based on orthodontic records).
