Abstract

The purpose of this activity is to provide precollege biology students a visual representation of evolution. Unfortunately, many resources begin with the start of life, which ignores the fact that the Earth is 4.6 billion years old. This model uses adding-machine tape to sequence events. Representation of major evolutionary and geologic events helps students visualize macroevolution.
