Antibiotic Resistance



Natural Selection

In 1998, a farmer sprayed his crops with the newest pesticide on the market and harvested a tremendous crop. In the summer of 1999, using the same chemical, he found that the corn borer insect ruined about one-eighth of his crop. The harvest of 2000 was a disaster. The farmer used the same chemical as always, but the pest decimated two-thirds of his crop. Believe it or not, this farmer's story can be explained by evolution. In this lesson, you will learn about how evolution affects your health, the food you eat, and your environment.
