Abstract
An approach to the teaching of natural selection in evolution using materials related to living creatures instead of artificial models such as toothpicks is described. Some investigations using simple flow tanks to investigate the stability of Gryphaea shells and a simulated non-visual searching for Cepaea are suggested for use in class practical sessions. All the designs for the investigations suggested have been tested with students and found to be workable in the relatively short practical periods available for school sixth-form and College of Education students.Keywords
