That several of the inhabitants of the caves of the Old and New Worlds should be closely related, we might expect from the well-known relationship of most of their other productions. As a blind species of Bathyscia is found in abundance on shady rocks
→far from
caves, the loss of vision in the cave-species
→of this one genus has
probably had no relation to its dark habitation;
it is
natural that an insect already deprived of vision should readily become adapted to dark caverns. Another blind genus (Anophthalmus) offers this remarkable
→the several distinct
species, as Mr. Murray
→has remarked, inhabit several distinct European caves and likewise those of Kentucky, and the genus is
found
except in
→but
it is possible that the
of these several
→whilst furnished with eyes, formerly may
have ranged
over both continents, and
→since (like the elephant on both continents) have
become extinct, excepting in their present secluded
Far from feeling
surprise that some of the cave-animals should be very anomalous, as Agassiz has remarked in regard to the blind fish, the Amblyopsis, and as is the case with the blind Proteus with reference to the reptiles of Europe, I am only surprised that more wrecks of ancient life have not been preserved, owing to the less severe competition to which the
of these dark abodes
have been exposed. |
