And yet there is no better evidence for the contemporaneity assumed by all who adopt the hypothesis of universal faunae and florae, of a universally uniform climate, and of a sensible cooling of the globe during geological time.
Judging from the present distribution of life, we cannot expect to find similar remains in geographically remote strata of the same age; and where, between the fossils of geographically remote strata, we do find much similarity, it is probably due rather to likeness of conditions than to contemporaneity.
And yet there is no better evidence for the contemporaneity assumed by all who adopt the hypothesis of universal faunae and florae, of a universally uniform climate, and of a sensible cooling of the globe during geological time.
But, pending the construction of a surer foundation than paleontology now possesses, it may be instructive, assuming for the nonce the general correctness of the ordinary hypothesis of geological contemporaneity, to consider whether the deductions which are ordinarily drawn from the whole body of paleontologic facts are justifiable.
Munro assigns to both sites "precisely the same chronological horizon," and also says that "there is no evidence" for the "contemporaneity of occupancy." This is not, as it may appear, an example of lack of logical consistency. If they made the things, the things are not modern forgeries.
But if it be a demonstrable fact that strata containing more than 60 or 70 per cent. of species of Mollusca in common, and comparatively close together, may yet be separated by an amount of geological time sufficient to allow of some of the greatest physical changes the world has seen, what becomes of that sort of contemporaneity the sole evidence of which is a similarity of facies, or the identity of half a dozen species, or of a good many genera?
And, indeed, so long as relative age only is spoken of, correspondence in succession 'is' correspondence in age; it is 'relative' contemporaneity.
But, pending the construction of a surer foundation than palaeontology now possesses, it may be instructive, assuming for the nonce the general correctness of the ordinary hypothesis of geological contemporaneity, to consider whether the deductions which are ordinarily drawn from the whole body of palaeontological facts are justifiable.
If the arguments which have been brought forward are valid, probably no one, in view of the present state of opinion, will be inclined to think the time wasted which has been spent upon their elaboration. End of Geological Contemporaneity and Persistent Types of Life. The subject upon which I wish to address you to-night is the structure and origin of Coral and Coral Reefs.
A crowd of spirits, by the very fact of their contemporaneity, feel themselves distracted and agitated all in the same way. Confusedly and provoked by the same sufferings they elaborate the same ideal and formulate the same desires. But they all wander along twilit paths on the side of the night where the light seems to be breaking through, without, however, being able to pierce the darkness.
