Why

Albert
Einstein
or
Leonardo

____________________
genius
?
People
generally
think
that
they
had
bigger
brains
,
but
I've
done
some
research
recently
and
I
don't
think
that
is
necessarily
true
.
I
found
____________________
2004
study
that
showed
that
____________________
size
of
____________________
whole
brain
might
not
be
that
closely
related
to
high
intelligence
.
In
this
study
,
scientists
found
that
____________________
volume
of
?
gray
matter
?
in
____________________
section
of
____________________
cerebral
cortex
had
more
influence
on
intelligence
than
on
____________________
total
volume
of
____________________
brain
.
In
fact
,
some
scientists
think
Einstein's
brain
was
smaller
than
many
?
normal
?
brains
,
but
it
had
fewer
fissures
and
more
connections
.
Intelligence
is
____________________
difficult
quality
to
define
and
it
appears
that
why
some
people
are
more
intelligent
than
others
might
also
be
more
complicated
than
it
first
appears
.
