Natural Selection Animation

This animation gives a great overview of how natural selection can cause change in a population. First it shows how a population of fruit flies can change over many generations. Then the video shows how anti-bacterial soap can actually cause strains of bacteria to become resistant to anti-bacterial chemicals.
Click on the "Evolution in Action" button at the link below to watch the experiment and check your understanding.

The "Subtitle" Button will let you read the narration in either English or Spanish.
