Comparative studies of different aspects of brain development in vertebrates and invertebrates reveal remarkable similarities in expression and function of key developmental control genes.

Indeed, vertebrates and invertebrates share a complex set of control genes and molecular genetic interactions that are responsible for neural induction, regionalized patterning, progenitor proliferation, and circuit formation in the developing brain.

This suggests that many of the molecular mechanisms involved in building the brains of extent bilaterians may already have been present in their common urbilaterian ancestor.
