Or again, turning to the other side of the
continent, it may be argued with some show of evidence
that America and Africa were once connected by land, and
that a sunken continent is to be traced between Brazil
and the Guinea coast.
Nevertheless, it appears to be impossible to say whether
or not an early branch of the human race ever 'migrated'
to America. Conceivably the race may have originated
there. Some authorities suppose that the evolution of
mankind occurred at the same time and in the same fashion
in two or more distinct quarters of the globe. Others
again think that mankind evolved and spread over the
surface of the world just as did the various kinds of
plants and animals. Of course, the higher endowment of
men enabled them to move with greater ease from place to
place than could beings of lesser faculties. Most writers
of to-day, however, consider this unlikely, and think it
more probable that man originated first in some one
region, and spread from it throughout the earth. But
where this region was, they cannot tell. We always think
of the races of Europe as having come westward from some
original home in Asia.
