Quiz 23


Question 1 of 4

We can’t yet fly like the birds or camouflage ourselves like the octopus, but humans frequently look to nature to improve our technology designs. One company is designing some unusual-looking blades for ventilation fans and windmills. They have bumps on their leading edge that accelerate the flow of air and produce more wind power in moderate winds. What animal body part inspired this design?


Humpback whale: Phillip Clapham, NOAA Fisheries
Fibonacci spiral: PAX Scientific
