The inhabitants of the sea are so infinitely more numerous than those of fresh-water, that on the according to mere doctrine of chance it is most probable that our our aquatic progenitor was a marine marine animal. Moreover many fresh-water animals have were been certain most productions animals have been primordially derived clearly been derived from the sea; a greater number seem, however, to have been derived from the land be modified modified terrestrial forms; modified & whether all terrestrial animals were first derived from the sea, we know not. All vital actions apparently tend to be periodical or go go excl by rhythm or fixed periods, & are animals acted on suffered exposed during during a long course of generations by tidal to the tides action could hardly fail to not come into concerted action with them. As our aquatic progenitor was probably a marine animal, it has sometimes occurred to me, as a more amusing speculation that the strong tendency previously allude to previously remarked on in so many terrestrial animals, for their normal & abnormal functions to be governed by lunar weeks, may be due to the relation of a periodic action first induced by the tidal changes actions
