If you like reading about design, there is an article called Technological Innovations From the Creator by Frank Sherwin, M.A. at ICR that you might want to read.
While some scientists will disagree with Sherwin that the designs in nature were created, I think everyone will agree that man’s mimicry has improved life for others and that the article is interesting.
Here is an excerpt:
We are all familiar with the life-saving property of blood clotting (a rare example of positive feedback in biology) in people and animals. This God-designed method has been copied for use in aircraft composite material. Composites are fiber-reinforced polymers with tiny hollow tubes filled with epoxy resin. When aircraft skin is overly stressed, a crack or a hole appears and the resin leaks out. The blemish is sealed and the material returns to 85 percent of its original strength.
