While there was some renewed interest in the theory in the 20th century due to the rise of disciplines like evolution, criminology, and anthropology, it soon was almost completely abandoned. This year, however, in the spirit of scientific fun, my colleagues decided to put this old theory to the test. They did so by repurposing various pieces of sophisticated software, originally designed for MRI brain analysis. Where normally these tools carefully discard all bits of skull, allowing analysis of the brain alone, they engineered them to do the reverse: relegating all of the brain to the trash, instead keeping the bony bits for analysis. From this surface structure, they could create a detailed map of the contours--bumps--of individual skulls.
