Joseph Cook taught that character tends to assume a fixt type, as
marked as in the case of mice, cited below:
Mice were originally natives of southern Asia. From there they
have accompanied man in his wanderings to all parts of the
world, traveling, as he has traveled, in ox-teams and on the
backs of donkeys, by steamship and railway; taking up their
quarters wherever he does, first in log-cabins with thatched
roofs; and finally, in some instances, on the nineteenth floor
of a steel building where generation after generation may live
and die in turn without having so much as touched foot to the
earth.
Strangely enough, the race seems to be proof against the
changes wrought upon most animals by difference in environment.
Specimens from the opposite sides of the globe, or from
widely separated latitudes, are said to be practically
indistinguishable, as if at last the species had hit upon a
style of form and coloring perfectly suited to all conditions of
life.--WITMER STONE and WILLIAM EVERETT CRAM,
“American Animals.”
