Brains vs Brawn: A Matter
of Evolution?
Scientists working at
Shanghai's CAS-MPG Partner Institute for Computation Biology, along
with some German scientists, were looking into the evolution of
metabolites, which are small molecules like sugars and amino acids,
and noticed that in humans, the main areas of concentration through
the evolutionary course were the brain and the muscles. The
scientists noticed that we had much faster metabolic growth in our
brains than most primates, and had much more change in metabolites in
our muscles than chimpanzees and other primates. After running some
strength trials, they had data reflecting how much stronger other
primates are compared to us. One of the hypotheses proposed by these
scientists was that the metabolic roles of human brain and strength
are connected. They stated that there is a possibility that we are
sparing energy for a strong brain at the cost of weak muscles.
