Introduction

Discover natural selection as a mechanism of evolution with the Amoeba Sisters. This video also uncovers the relationship of natural selection and antibiotic resistance in bacteria and emphasizes biological fitness. This video has a handout here: http://www.amoebasisters.com/handouts.html Note: This video is focused on natural selection. When we briefly mention evolution as 'change over time', this IS a bit too much of a simplification. We eventually hope to make a video specifically on evolution itself.

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky's certification and experience in teaching biology at the high school level. For more information about The Amoeba Sisters, visit: http://www.amoebasisters.com/about-us.html
