We have taken cues from nature’s most extreme examples to help ourselves in as many applications as possible. Huskies survive in the coldest places on earth and so are covered in thick fur, but can also avoid overheating in warmer climates. Based on their cooling methods scientists have developed the ‘Bear glove’ to help stop humans from overheating. Copying a giraffe’s ability to regulate the blood pressure in its head, Swiss scientists have developed a suit for fighter pilots to wear, allowing them to stay conscious when experiencing more than 9G. And crash helmets are now being improved by copying the way woodpeckers protect their brains when they undergo 1200G, hammering their head against a tree. We have learned from some of nature’s most extreme evolutionary adaptations to make our lives just that little bit easier and safer.
