The brain of modern humans is the result of the evolution of a building plan (Bauplan) that began its design 500 hundred millions years ago. This evolutionary scenario provides the basis for studies that seek to understand what is «conserved» and what is «new» between different vertebrates.

Building brains that can evolve

Evo-devo biology involves cross-species comparisons of entire developmental trajectories, not just of adult forms. This approach has proven very successful in general morphology, but its application to neurobiological problems is still relatively new.
