Darwin’s Reliance on Haeckel
nDarwin’s statements in “Origin of Species” depended on Haeckel’s work:
n“The embryos of the most distinct species belonging to the same class are closely similar, but becomes, when fully developed, widely dissimilar.”
n“With many animals the embryonic or larval stages show us, more or less completely, the condition of the progenitor of the whole group in its adult state.”
nDarwin
considered these similarities in early embryos “by far
the strongest single class of facts
in favor of” his theory.
