Our
prematurity
brought
a
second
big
advantage:
it
forced
us
to
communicate.
A
newborn
human
is
so
helpless
that
it
cannot
survive
without
communicating
its
needs.
Many
babies
died
in
the
past.
But
some
babies
were
better
at
signaling
their
needs,
and
some
mothers
were
better
at
interpreting
the
signals.
Babies
who
got
their
needs
met
lived
to
pass
on
their
genes
and
their
mother's
genes.
We
were
thus
naturally
selected
for
the
ability
to
communicate.
The replay is still saving.
