1 Artificial Selection Also called selective breeding

2 What is artificial selection? Humans choosing traits desirable to them rather than nature choosing traits that are passed on Humans have an effect on the evolution of a species rather than letting nature choose the path of evolution

3 When is artificial selection used? Domesticated animals such as dogs Farming crops and animals Pharmaceuticals (new drugs) Genetic engineering

4 Pros and Cons Pros: – Humans can manipulate organisms to benefit them – New variations of organisms can be produced (example: cabbage, broccoli, cauliflower are all variations of the same plant) Cons: – Selectively bred organisms are more susceptible to environmental changes and diseases – Inbreeding can become a problem – In animals artificial selection can cause health problems
