New study finds that human skull is highly integrated

 

 

A new study on a collection of 390 humans skulls from Austria challenges our current perceptions of evolution.  The skulls have shown that changes to the skull shape that have been thought to have occurred independently through separate evolutionary events may actually be highly integrated.  They found that changes in one part of the brain could drive changes in the other parts.  The researchers were able to use genetic information to simulate what would happen if natural selection had favored to use a particular shape change in the skull.
