This fact seemed too coincidental to him to be explained away by chance alone. Nevertheless, other geologists attempted to explain matching fossil forms an ocean apart not as the result of the movement of the continents, but instead as the result of the migration of flora and fauna—either across oceans or over ancient land bridges.17 This introduced a third hypothesis into the mix, one that, in conjunction with the coincidence hypothesis, could explain each of the same facts that Wegener’s hypothesis could.
