Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms.— George Gaylord Simpson
Contentment Genera quotations
It remains true, as every paleontologist knows, that most new species, genera, and families, and that nearly all categories above the level of families, appear in the record suddenly and are not led up to by known, gradual completely continuous transitional sequences.
Botany is based on fixed genera.
Unless mankind redesigns itself by changing our DNA through altering our genetic makeup, computer-genera ted robots will take over our world.
I accept extinction as best explaining disjoined species.
I see that the same cause must have reduced many species of great range to small, and that it may have reduced large genera to so small, and of families.
The names of the plants ought to be stable [certa], consequently they should be given to stable genera.
Universitas in modo citharae sit disposita, in qua diversa genera in modo chordarum sit consonantia. The universe is arranged like a cithera, in which different kinds of things sound together harmoniously, just as they do in a chord.
The close relationship between railroad expansion and the genera development and prosperity of the country is nowhere brought more distinctly into relief than in connection with the construction of the Pacific railroads.
People began to understand that with the acquisition of California the nation had obtained practically half a continent, of which the future possibilities were almost unlimited, so far as the development of natural resources and the genera production of wealth were concerned.
Is it philosophical, is it quite allowable, to assume without evidence from fossil plants that the family or any of the genera was once larger and wide spread? and occupied a continuous area?
Every paleontologist knows that most new species, genera, and families, and that nearly all categories above the level of family appear in the record suddenly and are not led up to by known, gradual, completely continuous transitional sequences.
Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms.
The natural historian is not a fisherman who prays for cloudy days and good luck merely; but as fishing has been styled "a contemplative man's recreation," introducing him profitably to woods and water, so the fruit of the naturalist's observations is not in new genera or species, but in new contemplations still, and science is only a more contemplative man's recreation.
Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.
Anglers may be divided into almost as many genera and species as the fish they catch, and engage in the sport from as many impulses.
God is not related to creatures as though belonging to a different "genus," but as transcending every "genus," and as the principle of all "genera.
Established species are evolving so slowly that major transitions between genera and higher taxa must be occurring within small rapidly evolving populations that leave NO LEGIBLE FOSSIL RECORD.
We admit as many genera as there are different groups of natural species of which the fructification has the same structure.
In general, the more one augments the number of divisions of the productions of nature, the more one approaches the truth, since in nature only individuals exist, while genera, orders, and classes only exist in our imagination.
