In this activity from ARKive, students look for similarities between the basic body plans of different vertebrates as evidence of evolutionary change.

This customisable PowerPoint presentation builds the scientific explanation of natural selection by illustrating four key observations:
All organisms produce more offspring than survive to adulthood.
Populations remain more or less constant in numbers.
