"We were the first to consider extensive genetic data to actually exclude genetic explanations for the behavior," says Krützen. He and his team took tissue samples from 185 dolphins in Shark Bay, thirteen of which were known adult spongers. Only one of these spongers was male. The researchers genotyped each individual for 12 bi-par
