When two groups of organisms independently evolve similar adaptations, it’s called convergent evolution. The development of flukes was the last step in the whale's evolution from land animal to water animal. For the most part, killer whales in the wild are visible only when they are at the surface, so it is inherently challenging to document and study whale behavior.
