She returned every week for 12 weeks to measure survival of tagged lizards. And many birds have mastered a stroke that any human swimmer might envy. Their feet are webbed and this trait makes them fast swimmers. Different vertebrate species with webbed feet have different mutations that disrupt this process, indicating that the structure arose independently in these lineages. Birds are typically classified as a sub-group of reptiles, but they are a distinct class within vertebrates, so are discussed separately.
