Want To Fly? Don't Copy The Birds And The Bees

Since earliest recorded history, and presumably beyond, humans have always wanted to fly. First attempts involved imitation of winged creatures around them, and unfailingly ended in disaster. No workable flying machines have ever looked particularly similar to nature's fliers, and today there is little comparison between a top of the range military chopper and the humble bumblebee, despite similar flight patterns.

In an era in which engineers are increasingly exploiting designs from nature, understanding this paradox is becoming ever more important. Dr Jim Usherwood, from the Royal Veterinary College, has studied the reasons behind these differences in aerodynamics and concluded that scientists should, in this instance, be more hesitant before imitating nature. He presented his results on Sunday 6th July at the Society for Experimental Biology's Annual Meeting in Marseille, France.
