However, during evolution, the number of skull bones was successively reduced in early mammals around 150 to 100 million years ago., an international team of paleontologists show how they used computer simulations and stress analyses to investigate the purpose of this skull simplification. commented: “Reducing the number of bones led to a redistribution of stresses in the skull of early mammals. Stress was redirected from the part of the skull housing the brain to the margins of the skull during feeding, which may have allowed for an increase in brain size.
