Mother of all brains

All brains originated from a single common ancestral brain that emerged at least 700 million years ago, according to a recent analysis of brain studies.

    “What we see today in humans, insects and all other multicellular animals with a central nervous system are probably just variations of one ancient scheme”

The researchers don’t know what the organism that contained the mother of all brains looked like – and don’t know what the ancient brain looked like either. However, they believe that the basic genetic mechanisms and the principal chemical setup was in place before the major animal phyla diverged.
