A popular textile Velcro is a prime example of applying wildlife knowledge to technical devices. The convenient method of fastening, which we now use, arose thanks to a simple burdock.
Burdock seed baskets covered with bristles with small hooks at the end clung to the coat of the dog of the French engineer Georges Mestral. The bottom line is the patented invention of a fastener called “velvet hook” or velcro Velcro.
