The brain of each animal shows specific traits that reflect its phylogenetic history and its particular lifestyle. Therefore, comparing brains is not just a mere intellectual exercise, but it helps understanding how the brain allows adaptive behavioral strategies to face an ever-changing world and how this complex organ has evolved during phylogeny, giving rise to complex mental processes in humans and other animals. These questions attracted scientists since the times of Santiago Ramon y Cajal one of the founders of comparative neurobiology. In the last decade, this discipline has undergone a true revolution due to the analysis of expression patterns of morphogenetic genes in embryos of different animals.
The title of the Research Topic, Adaptive Function and Brain Evolution, stresses the importance of comparative studies to understand brain function and, the reverse, of considering brain function to properly understand brain evolution. This issues should be taken into account when using animals in the research of mental function and dysfunction. The papers of this Research Topic are focused onto the following four Grand Questions of comparative neurobiology:


1) How are different brains built during ontogeny?;

2) What is the anatomical organization of mature brains and how can they be compared?;

3) How do brains work to accomplish their function of ensuring survival and, ultimately, reproductive success?;

4) How have brains evolved during phylogeny?.


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
