How did smart crow beak adapt to tool use?
From ScienceDaily: “This study shows that the unique bill contributes to the birds’ ability to use and probably make tools,” he said. “We argue that the beak became specialized for tool manipulation once the birds began using tools, and that this enhanced tool manipulation ability may have allowed the crows to make more complex tools.” Probably. It works that way with appendages too. In fact, some differences in apparent animal intelligence may come down to whether the animal can carry out an action for its own benefit. Shellfish are closer anatomically to octopuses than birds are but both octopuses and birds can use body parts to do something. Shellfish can’t. Can we quantify intelligence apart from the ability to demonstrate Read More ›
