After two tremendous growth spurts — one in size, followed by an
even more important one in cognitive ability — the human brain is now a
lot like a teenage boy.

It consumes huge amounts of calories, is rather temperamental and,
when harnessed just right, exhibits incredible prowess. The brain's

suggests.

To understand what caused the cognitive spurt, Khaitovich and
colleagues examined chemical brain processes known to have changed in
the past 200,000 years. Comparing <A href="http://www.livescience.com/animals/061024_brain_diet.html" linkindex="28">apes and humans</A>, they found the most robust differences were for processes involved in energy metabolism.
