Review your understanding of artificial selection in this free article aligned to NGSS standards.
- Humans use artificial selection to develop organisms with useful or desirable traits. All crop plant varieties, types of livestock, and dog breeds are the result of artificial selection.
- Another term for artificial selection is selective breeding.
- During artificial selection, humans choose parent organisms with specific traits and allow them to reproduce. This is repeated over many generations. Eventually, this process gives rise to new types of organisms.
- The types of organisms that result from artificial selection are considered domesticated.
- Artificial selection is similar to natural selection. During both processes, traits (and their underlying genes) change in a group of organisms. And, this change is based on which organisms are more likely to reproduce.
- There is one key difference between artificial selection and natural selection. During artificial selection, humans choose which individuals will reproduce. This is not the case during natural selection.

- Selective breeding was established as a scientific practice by Robert Bakewell during the British Agricultural Revolution in the 18th century. Arguably, his most important breeding program was with sheep. Using native stock, he was able to quickly select for large, yet fine-boned sheep, with long, lustrous wool. does that help?(2 votes)
