David Attenborough's Natural Curiosities: Curious Minds

Sir David Attenborough examines the mysteries behind some of nature's most fascinating creatures and plants. Here, he looks at how the curious minds of orangutans and crows helped them become inventive. Orangutans are clever tool users but strangely such skills remained undiscovered for centuries. They were considered to be just clever mimics until a discovery in remote Sumatran swamps revealed their true potential. Crows are clever birds that can solve problems, and they too make surprisingly sophisticated tools.
