In 1978 scientists figured out how to implant traces of human DNA into E. Coli bacteria. This allowed the scientists to breed bacteria that produced human insulin. Insulin is a chemical that humans produce to help regulate blood sugar. Without insulin, people would die. Some people can’t produce the proper amount of insulin on their own, so being able to manufacture it in a lab using bacteria literally saves millions of lives a year. Can you think of another problem that selective breeding could solve? How could you use selective breeding to solve that problem? What would you need to do?
