Who is natural?

Selective breeding is a key method used in developing cultivated breeds in domesticated animals. Inspired by Charles Darwin's work in "Origin of Species," this process involves carefully choosing parent animals with desirable traits to produce offspring that inherit those traits. Techniques such as inbreeding, linebreeding, and outcrossing are employed to lock in or introduce favorable characteristics. It is widely used in various fields, including show dogs, agriculture, and horse racing, to enhance specific attributes in animal populations over generations.

  1. Who is natural? A B

  2. BOTH!! But How? SELECTIVE BREEDING

  3. Definition • “in domesticated animals is the process of a breeder developing a cultivated breed over time”—wikipedia

  4. Historically • Charles Darwin • Origin of Species—1859 • Journey of the Beagle • Finches with different attributes on the Galapagos islands

  5. What do you do? • Picking out desirable qualities to pass on to offspring • Breed the appropriate male and female species together to produce that offspring • Rebreed as many times as necessary to get the desire traits

  6. Techniques • Inbreeding: breeding between close relatives • Can lock in desirable traits to a population • Linebreeding: like inbreeding, but farther away relatives (i.e. cousins) • Can lock in desirable traits without causing damage to population • Outcrossing: introducing new traits • Introduce desirable traits

  7. Why? • Show dogs • Farmers • Horse racing
