This is a great example of ingenuity. We humans tend to have 'not invented here' syndrome. We understand so little about nature and ourselves that we often don't look for solutions that already exist. We are so often excited about, in the case of the bike world, new alloys and ways to weld lightweight metals that we often overlook existing solutions. This is definitely happening in the world of medicine.
My point? Get out of the house and get in touch with the great outdoors. Nature has solved many problems for a very long time. So maybe we can learn something from it that we can apply to our trivial day to day issues.
