===> Musical lizard brain (Evolution)
"Some researchers take the next step and say an ear for music goes back much further than Homo sapiens. As
evidence they point to neurological studies of the human brain as it responds to music. PET scans of people
listening to music have confirmed what many music lovers already know, that music elicits a response in that
part of the brain that deals with our emotions.

As a recent issue of Scientific American pointed out, our emotional nerve centre - the limbic system - is an
evolutionarily ancient part of our brain, and one which we share with much of the animal kingdom. Our limbic
system’s response to music suggests that there is a deep evolutionary significance in our musical behaviour. As
Patricia Gray, head of the Biomusic program at the National Academy of Sciences in the U.S. suggests, it seems
that the roots of human music lie much closer to our “lizard brain” than to our more recent reasoning cortex.
She proposes that music has a more ancient origin even than human language.
This accounts only for its direct relation, exonential relation to intelligence..
...humans and whales last shared a twig on the family tree 60 million years ago. Patricia Gray suggests (if
whales could sing..) that this makes humans not the inventors of music, but rather latecomers to the party.
The point is
development
not the late coming but the the human intelligence achieved through the
of music and culture ..
"Another idea is that music conferred an evolutionary advantage by promoting social cohesion among groups.
Singing, dancing and banging drums around the campfire may have been a powerful social glue, giving the
participants a sense of community. The stronger the bonds, goes the theory, the better the survival rate of
members of the group.
Or perhaps music is a mind game designed to train us to think creatively and find patterns in our surroundings.
The human skill at pattern recognition, which has clear evolutionary advantages because it helps us understand
and make predictions about our world, might have been honed over the years by making and listening to music.
