When was selective breeding discovered

This was the reason to start recording pedigree on paper, so that correct information could be reproduced and it could be proven that an animal was of a certain breed. The first herdbook was for the thoroughbred horse and was established in England in This book did not contain all pedigree, but only those of horses that were winning important races. Following the race horses, the Shorthorn cattle were next to start a herdbook.

In the rest of Europe, herdbooks only started to be established in from onwards for horses in France , and from onwards for cattle also in France. The first international herdbook was established for the American Berkshire pigs in The first dog in the Netherlands was registered by the Koningklijke Nederlandsche Jachtvereeninging Nimrod predecessor of the Raad van Beheer op Kynologisch Gebied in Nederland in After the turn of the century animal breeding within herdbook settings became standard.

With the establishments of herdbooks, breeds were formed. The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit.

In the mids, Charles Darwin famously described variation in the anatomy of finches from the Galapagos Islands.

Alfred Russel Wallace noted the similarities and differences between nearby species and those separated by natural boundaries in the Amazon and Indonesia.

Independently they came to the same conclusion: over generations, natural selection of inherited traits could give rise to new species. His work is said to have been conducted at first with more or less secrecy so far as the public was concerned.

Aware of the general prejudice existing at the time against close breeding, he probably did not care to call down criticism while still experimenting. Some have intimated that in the case of his "improved Leicesters" he was actuated by a desire to conceal one of the real sources of the betterment attained.

One story ran to the effect that he had used in his earlier experiments an extraordinary black-face "tup," which no visitor was ever permitted to see, and the occasional appearance of blackish lambs among the descendants of the Dishley sheep long years later was cited as an illustration of the power of atavism or reversion to an original type even after the lapse of many generations.

Naturally, progress was more rapid with the Leicesters than the Longhorns, and it was not long before the flockmasters of the entire kingdom were taking notice of the marvels being wrought.

One celebrated ram, Two Pounder , is said to have earned Guineas in a single season! The improvement of the Longhorns followed, and the Dishley "breed" became the prevailing popular type in all the neighboring districts. He is said to have maintained somewhat of a "museum," or as Dixon calls it, a "business room," in which there were preserved both skeletons and "pickled carcasses" illustrating interesting results attained.

Among these later trophies of the Longhorns were some joints that were prized relics of Old Comley , that died at the good old age of 26, with fully four inches of outside fat upon his sirloin. The herd was distinguished above all others for its depth of flesh, and Bakewell did not for a moment doubt that he had evolved a type which would "represent the roast beef of old England forever and aye. King George III became interested, and honored the wizard with a royal inquiry as to his "new discovery in stock breeding.
