Ancient
humans who took a leap forward in stone tool technology 1.75 million
years ago may have been budding musicians, research suggests.

The
brain circuits that led to two-sided tools and weapons such as
hand-axes and cleavers are the same as those activated when playing a
piano, a study has shown.
The
switch from simple flake and pebble technology known as "Oldowan"
to more sophisticated "Acheulian" tool know-how is
considered a hugely important step in human evolution.

To
investigate what brought about the change, British and US scientists
conducted brain scans of volunteers as they learned to make Oldowan
and Acheulian tools.

They
found that Acheulian tool manufacture required a combination of
visual memory, hearing, movement awareness and action-planning - all
essential ingredients of being a musician.

Professor
John Spencer, from the University of East Anglia, said: "Our
findings do not neatly overlap with prior claims that language and
stone tool production co-evolved. There is more support for the idea
that working memory and auditory-visual integration networks laid the
foundation for advances in stone tool-making.
"It
is fascinating that these same brain networks today allow modern
humans to perform such behaviours as skilfully playing a musical
instrument."
People
living 1.75 million years ago had not yet developed any kind of
sophisticated language, so the evolution of language circuits in the
brain is not thought to have helped them upgrade to Acheulian tools.
The
study, published in the journal Nature Human Behaviour, used an
advanced form of brain scan called functional near-infrared
spectroscopy (fNIRS) to track the volunteers' neural activity in real
time. Fifteen
of the 31 participants learned to knap stone by watching videos
accompanied by verbal instruction. The other 16 acquired the skill
using the same videos, but with the sound turned off
Study
leader Dr Shelby Putt, from the Stone Age Institute in Indianapolis,
US, said: "This work offers novel insights into prehistoric
cognition using a cutting-edge neuro-imaging technique that allows
people to engage in complex actions while we are measuring localised
brain activity.
"The
study reveals key brain networks that might underlie the shift
towards more human-like intelligence around 1.75 million years ago.
We think this marked a turning point in the evolution of the human
brain, leading to the evolution of a new species of human."
US
co-author Professor Robert Franciscus, from the University of Iowa,
said the evolution of modern intelligent humans remained a "great
mystery".

He
added: "We discovered that the appearance of a type of more
complexly shaped stone tool kit in the archaeological record marked
an important cognitive shift when our ancestors started to think and
act more like humans rather than apes."
