繼人類和類人猿,烏鴉成為創造合成工具的第三物種
Crows Become Third Species to Create Compound Tools, After Humans and Great Apes
Remember when you learned that tool-making was one of the major features that set humans apart from all other animals? Well, that wasn't wholly true—everything from elephants to dolphins to insects use simple tools to survive, as outlined in this excellent National Geographic article. But complex tools, ones made of multiple parts, have only been observed in humans and great apes...until now. A recent study has shown that New Caledonian crows have the ability to make complex tools, and they're good at it, too.
