The ground is full of seeds that cannot rise into seedlings;
the seedlings rob one another of air, light and water, the
strongest robber winning the day, and extinguishing his
competitors.
Year after year, the wild animals with which
man never interferes are, on the average, neither more nor
less numerous than they were; and yet we know that the
annual produce of every pair is from one to perhaps a
million young; so that it is mathematically certain that,
on the average, as many are killed by natural causes as
are born every year, and those only escape which happen
to be a little better fitted to resist destruction than
those which die. The individuals of a species are like
the crew of a foundered ship, and none but good swimmers
have a chance of reaching the land.
