Described are simulations that can be used to illustrate evolution by natural selection. Suggestions for simulating phenomena such as adaptive radiation, color match to background and vision of predators are offered. (BR)

Suggests classroom projects for investigating the diversity of insects. (LS)

It is suggested that the work of Kammerer provides suitable material, in the form of case studies on which to base discussions of Lamarckism versus Darwinism. A set of structured problems is described as an example of possible problem-solving exercises, and further experiments to extend Kammerer's work are outlined. (Author/MA)

Presented are ideas for the teaching of natural selection using materials related to living creatures instead of artificial models such as toothpicks. Some investigations using simple flowtanks to investigate the stability of Gryphaea shells and a simulated non-visual search for Cepaea are suggested. (Author/AJ)
