“When we come to consider specific characters, we see that a difference exists—that, in short, the species and even genera are no longer represented upon earth. More than this, it will be found that the earliest species comparatively soon gave place to others, and that they are not represented even in the next higher group of rocks.”

Context: We may understand why the species of the same genus, or genera of the same family, resemble each other more nearly in their embryonic than in their more fully developed state, or how it is that in the eyes of most naturalists the structure of the embryo is even more important in classification than that of the adult, 'for the embryo is the animal in its less modified state, and in so far it reveals the structure of its progenitor. In two groups of animals, however much they may at present differ from each other in structure and habits, if they pass through the same or similar embryonic stages, we may feel assured that they have both descended from the same or nearly similar parents, and are therefore in that degree closely related. Thus community in embryonic structure reveals community of descent, however much the structure of the adult may have been modified.

Species of Panthera include the lion Panthera leo, the tiger P. tigris, and the leopard P. pardus, among others. So saying Tyrannosaurus is much like saying "the big cats".

Context: Survivors represent a separate species, just like an animal species. We are all survivors, that is what determines our perverse and degenerate mental world. Auschwitz.

The Historical Illuminatus as spoken by Sigismundo Celine
Context: The creative faculty, the god-power, is not used here with anything less than literalness. When beauty was created by a godly mind, beauty existed, as surely as the paintings of Botticelli or the concerti of Vivaldi exist. When mercy was created, mercy existed. When guilt was created, guilt existed. Out of a meaningless and pointless existence, we have made meaning and purpose; but since this creative act happens only when we relax after great strain, we feel it as 'pouring into us' from elsewhere. Thus, we do not know our own godhood and we are perpetually swindled by those who assure us that it is indeed elsewhere, but they can give us access to it, for a reasonable fee. And when we as a species were ignorant enough to be duped in that way, the swindlers went one step further, invented original sin and other horrors of that sort, and made us even more 'dependent' upon them.
