The silk produced by spiders is very different from the silk produced by silkworms in some very important ways. While silkworm silk is strong yet not prone to stretching, spiders make silk that is both strong and stretchy. They also make several different kinds of silk, each with its own purpose.
In fact, spider silk is stronger than an equal amount of steel and yet it stretches. Spider silk is made of nothing more than proteins. However, scientists are finding it extremely difficult to study the chemical structure of spider silk because it resists most of their efforts to break it down into its chemical parts. Scientists have finally resorted to hot, concentrated acids to break down the silk. They are learning that one type of spider silk is made up of lengths of very stiff amino acids, separated by segments of amino acids that form a springy helix. Together they contribute to the strength and stretchiness of spider silk.
Scientists are exploring how spider silk is made because this wonderful material promises new methods for creating stronger and lighter materials for human use. One possible use would be making cloth that is both comfortable and bulletproof.
God has done all things well. The fact that we can learn to design better things by learning how He designed things is a witness for His wisdom as well as a witness against claims that the creation designed itself by trial and error. However, there is much more to God's plans for us, as you can learn from the Bible.
