We had two activities. Dance Dance Evolution is a computer game which uses an adapted dance-dance mat with four squares representing bases in the DNA (A, C, G and T). Participants act as the DNA replicator, and mistakes cause mutations in the DNA sequence. The next dancer copies the sequence left by the previous dancer, demonstrating evolution by mutation over time. The game shows the percentage similarity of the current sequence to the original sequence, showing the amount of 'evolution' over the time period of the game. We discussed with visitors the relevance of this to the development of antibiotic resistance.
