Abstract

The article of Finlay et al. is an excellent example of identifyingconstraints in the development of the brain, and their implicationson brain architecture in evolution. Here we further illustrate theimportance of constraints by presenting a few examples of how asmall number of biophysical mechanisms or even a single life historyparameter can have an enormous impact on brain evolution.
