sketch of the progress of opinion on the Origin of Species. Until recently the great majority of naturalists
believe

that species

believe

that species undergo modification, and that the existing forms of life are the descendants by true generation
from
of
pre-existing forms. Passing over allusions to the subject in the classical writers, ∗ the first author who in modern times has treated it in a scientific spirit was Buffon. But as his opinions fluctuated greatly at different periods, and as he does not enter on the causes or means of the transformation of species, I need not here enter on details.
