Ancestral brain (‘mother of all brains”)

News in Science – Probed! Mother of all brains – 28/09/2005: “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.

The finding suggests this mother brain for all creatures with a central nervous system – such as insects, birds, animals and humans – evolved only once before each species underwent its own evolutionary course.

‘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,’ says Dr Rudi Loesel, who conducted the analysis published in the journal Arthropod Structure & Development.”

Wow. This underscores just how alien any intelligent alien life will be from the Earthly model.
