01 - Variations Under Domestication 01-09 - Principles of Selection anciently followed, and their Effects 40 The same principles are followed by horticulturists; but the variations are here often more abrupt.

No one supposes that our choicest productions have been produced by a single variation from the aboriginal stock.

We have proofs that this has not been so in several cases in which exact records have been kept; thus, to give a very trifling instance, the steadily-increasing size of the common gooseberry may be quoted.

We see an astonishing improvement in many florists' flowers, when the flowers of the present day are compared with drawings made only twenty or thirty years ago.

When a race of plants is once pretty well established, the seed-raisers do not pick out the best plants, but merely go over their seed-beds, and pull up the "rogues," as they call the plants that deviate from the proper standard.

With animals this kind of selection is, in fact, likewise followed; for hardly any one is so careless as to breed from his worst animals.
02 - Variations Under Nature 02-03 - Doubtful Species 40 Many of the cases of strongly-marked varieties or doubtful species well deserve consideration; for several interesting lines of argument, from geographical distribution, analogical variation, hybridism, &c., have been brought to bear in the attempt to determine their rank; but space does not here permit me to discuss them.
01 - Variations Under Domestication 01-10 - Methodical and Unconscious Selection 40 If there exist savages so barbarous as never to think of the inherited character of the offspring of their domestic animals, yet any one animal particularly useful to them, for any special purpose, would be carefully preserved during famines and other accidents, to which savages are so liable, and such choice animals would thus generally leave more offspring than the inferior ones; so that in this case there would be a kind of unconscious selection going on.

We see the value set on animals even by the barbarians of Tierra del Fuego, by their killing and devouring their old women, in times of dearth, as of less value than their dogs.

01 - Variations Under Domestication 01-11 - Unknown Origin of our Domestic Productions 40 Nor let it be thought that some great deviation of structure would be necessary to catch the fancier's eye: he perceives extremely small differences, and it is in human nature to value any novelty, however slight, in one's own possession.

Nor must the value which would formerly have been set on any slight differences in the individuals of the same species be judged of by the value which is now set on them, after several breeds have fairly been established.

I is known that with pigeons many slight variations now occasionally appear, but these are rejected as faults or deviations from the standard of perfection in each breed.

The common goose has not given rise to any marked varieties; hence the Toulouse and the common breed, which differ only in colour, that most fleeting of characters,have lately been exhibited as distinct at our poultry shows.
