Página 574 - In conclusion, I may say, that the fossil remains of Man hitherto discovered do not seem to me to take us appreciably nearer to that lower pithecoid form, by the modification of which he has, probably, become what he is.
Página 520 - The positive change in passing from the recent to the ancient animal world is greater, but still singularly small. No fossil animal is so distinct from those now living as to require to be arranged even in a separate class from those which contain existing forms. It is only when we come...
Página 518 - In commencing these remarks, mention was made of the great obligations under which the naturalist lies to the geologist and palaeontologist. Assuredly the time will come when these obligations will be repaid tenfold, and when the maze of the world's past history, through which the pure geologist and the pure palaeontologist find no guidance, will be securely threaded by the clue furnished by the naturalist. All who are competent to express an opinion on the subject are at present agreed that the...
Página 527 - ... fossiliferous rocks now known are coeval with the commencement of life, and if their contents give us any just conception of the nature and the extent of the earliest fauna and flora, the insignificant amount of modification which can be demonstrated to have taken place in any one group of animals, or plants, is quite incompatible with the hypothesis that all living forms are the results of a necessary process of progressive development, entirely comprised within the time represented by the fossiliferous...

Página 392 - Ah my God, What might I not have made of thy fair world, Had I but loved thy highest creature here ? It was my duty to have loved the highest: It surely was my profit had I known : It would have been my pleasure had I seen. We needs must love the highest when we see it, Not Lancelot, nor another.
Página 89 - Again, certain well-marked forms of living beings have existed through enormous epochs, surviving not only the changes of physical conditions, but persisting comparatively unaltered, while other forms of life have appeared and disappeared. Such forms may be termed " persistent types " of life; and examples of them are abundant enough in both the animal and the vegetable worlds.
Página 90 - If, on the other hand, we view 'Persistent Types' in relation to that hypothesis which supposes the species living at any time to be the result of the gradual modification of pre-existing species...
Página 526 - It negatives those doctrines ; for it either shows us no evidence of any such modification, or demonstrates it to have been very slight ; and as to the nature of that modification, it yields no evidence whatsoever that the earlier members of any long-continued group were more generalised in structure than the later ones.
Página 517 - ... contemporaneity" becomes incalculable, and proves the constant source of gratuitous speculations. For anything that geology or palaeontology are able to show to the contrary, a Devonian fauna and flora in the British Islands may have been contemporaneous with Silurian life in North America, and with a Carboniferous fauna and flora in Africa. Geographical provinces and zones may have been as distinctly marked in the Palaeozoic epoch as at present, and those seemingly sudden appearances of new...
