Here is a great video to introduce children (and adults) to how evolution actually works in the real world. Here is the description and credits from the video below.
The mechanisms of evolution explained in one video.
The theory of evolution explains how the enormous variety of life could come into existence. How it is possible for primitive life forms to spawn the millions of different creatures, that exist today. Unfortunately, evolution is often misunderstood, because it’s mechanisms seem counter intuitive. So this video aims to explain the mechanisms of evolution in a way, easily understandable: A short animation film. By using visualizations, infographics and appealing characters, the viewer is more likely to understand it the complex information. More than that, by presenting the information in an entertaining way, the information is more likely to sink in.
