as Mr. G. H. Lewes remarks, "has gills, and passes its existence "in
the water; but the Salamandra atra, which lives "high
up among the mountains, brings forth its young "full-formed.
This animal never lives in the water.
"Yet
if we open a gravid female, we find tadpoles "inside
her with exquisitely feathered gills; and when "placed
in water they swim about like the tadpoles of the "water-newt.
Obviously this aquatic organisation has "no
reference to the future life of the animal, nor has "it
any adaptation to its embryonic condition; it has "solely
reference to ancestral adaptations, it repeats a "phase
in the development of its progenitors."
