Development Of Airplanes Is Like Biological Evolution, Engineer Says

Airplanes and birds may have followed similar pattern to increase efficiency.

The development of passenger aircraft over the past century mirrors the evolution of flying animals, and shows that evolution is not just a biological phenomenon, according to a paper published today in the Journal of Applied Physics.

Adrian Bejan, a mechanical engineer at Duke University in Durham, North Carolina, argues that evolution is a physical phenomenon, with changes in animals driven by physical laws. In the case of birds, the factors include aerodynamics.

“I want to persuade people that evolution – that is the change in [body shape] over time – recognizes no distinction between the two camps of biology and physics,” he said. Read more in Inside Science.
