Sometimes an animal copes with a changed situation,
not by adapting to it, but by moving away from it to another
location. There, it may still have to adapt, but the type
of adaptation may be easier. There are primitive races
of man that have attempted to avoid the pressures or
changes that civilization brings. They have had to
adjust to living in remote or harsh conditions. Examples
are the pygmies of the Congo who have escaped into
the thickest jungles which are full of dangers. They
have learned to obtain a living there and to cope with
wild animals. African bushmen manage
to live off the arid Kalahari Desert where there is hardly
any other life. Life is tough for the bushmen but they
are left in peace. These social adaptations could well
lead to biological adaptations over a number of
generations, but this is a very slow progress and it is
unlikely that any single person would be aware of it
taking place.
