Artificial Selection and Genetic Engineering

The video explains evolution as a change in species characteristics over time, occurring naturally through natural selection or artificially through human intervention. Artificial selection involves selective breeding, where desired traits are bred into organisms, as seen in plants like broccoli and animals like dogs. Genetic engineering, a more recent method, directly manipulates DNA to achieve desired traits, leading to GMOs. The video compares the slower process of selective breeding with the faster results of genetic engineering, highlighting their roles in influencing evolution.

What is the term for the process where humans influence the traits passed on in species?

• Artificial selection

• Genetic drift
