Here's another example of observed evolution:
The nylon problem
In 1975, Japanese scientists reported the discovery of bacteria that could break down nylon, the material used to make pantyhose and parachutes. Bacteria are known to ingest all sorts of things, everything from crude oil to sulfur, so the discovery of one that could eat nylon would not have been very remarkable if not for one small detail: nylon is synthetic; it didn't exist anywhere in nature until 1935, when it was invented by an organic chemist at the chemical company Dupont.
The discovery of nylon-eating bacteria poses a problem for ID proponents. Where did the CSI for nylonase—the actual protein that the bacteria use to break down the nylon—come from?
There are three possibilities:
* The nylonase gene was present in the bacterial genome all along.
* The CSI for nylonase was inserted into the bacteria by a Supreme Being.
* The ability to digest nylon arose spontaneously as a result of mutation. Because it allowed the bacteria to take advantage of a new resource, the ability stuck and was eventually passed on to future generations.
Apart from simply being the most reasonable explanation, there are two other reasons that most scientists prefer the last option, which is an example of Darwinian natural selection.
First, hauling around a nylonase gene before the invention of nylon is at best useless to the bacteria; at worst, it could be harmful or lethal. Secondly, the nylonase enzyme is less efficient than the precursor protein it's believed to have developed from. Thus, if nylonase really was designed by a Supreme Being, it wasn't done very intelligently.
