endeavour to sleep away the winter in a drowsy condition. At the
first breath of spring they emerge—‘ but not the six hundred.’ Frost
and hunger have killed most of them off; only one or two queens
out of all the pioneers which went forth from the old nest have lived
through the hard times to become the foundresses of new colonies
and future dynasties.”—(Grant Allen. Longman's Magazine, vol. xxiii.,
P- ¿22.)
Here we are told that the survival of one queen
rather than another “is decided in nature’s rough-and-
ready fashion by the chances of survival.” That is the
way in which this well-informed and charming writer
describes a struggle which we should have expected to
have resulted in the strictest survival of the fittest.
The case of the termites is no more favourable to
any process of selection such as the theory requires.
“ In the evening, soon after the first tornado, which proclaims the
approach of the ensuing rains, the males and females emerge from
their clay-built citadels by myriads and myriads to seek their fortune.
Borne on ample wings and carried by the wind, they fill the air. The
next morning they are discovered covering the surface of the earth
and waters, deprived of the wings which before enabled them to
avoid their numerous enemies, and looking like large maggots. They
are the prey of innumerable enemies, to the smallest of which they
make not the least resistance. Insects, especially ants, which are always
on the hunt for them, leaving no place unexplored ; birds, reptiles,
beasts, and even man himself, look upon this event as their harvest
and make them their food ; so that scarcely a single pair in many
millions get into a place of safety and lay the foundation of a new
community.”—(Kirby and Spence. Ento?nology. p. 308.)
The only arguments adduced by Mr. Darwin in favour
of his hypothesis—the existence of gradations of structure
—are (1st) the fact of correlation, and (2nd) the fact of
gradations in the forms of neuter insects. But neither
of these facts can be accepted as a proof of the action
of Natural Selection. They are indicative, it may be, of
the way in which the transmutation of certain specific
forms has been brought about, but they do not in
