(cont'd from yesterday's post)
Different species of spiders make webs of special kinds: collars, trapdoors, tunnels, as well as the familiar net design. But exactly how do they know which kinds of proteins to combine that will give the web its flexibility, its legendary strength, its stickiness? And where to put the anchor points? Spiders don't make conscious choices of biochemistry, geometry, engineering.
Instinct is not an answer. It's a way of saying "we don't know." A credible path to evolutionary development of the biological web-building system would require every necessary gene mutation on that pathway to render a survival advantage of some kind (natural selection). A biologist and spider specialist says it may be impossible to figure it out.
Complex functions and behaviors like this bear a strong resemblance to a human engineering project, a very intentional and rational activity that involves mathematical and chemical formulas.
Maybe science will someday discover algorithms somehow built into the genome. Coded information doesn't come from random material causes. But it would be consistent with the Creator God hypothesis.
