Where do all those disease-resistant bacteria come from?
Perhaps the best example of evolution at work is some moths in England.
They rest on the bark of trees during the day and matched the bark
perfectly. Then came the industrial revolution and coal heating and the
trees all got covered with soot and were black. In only a few years the
moths had all darkened to the same shade as the soot. The mechanism was
simple. Birds ate the moths that kept the old coloring and didn't see and
eat the few black ones that appeared as a result of natural mutations.
Those dark moths mated and produced dark offspring. Birds weeded out the
lighter ones. Today the smoky old factories are gone and fewer people
heat with smoky, sooty coal. The trees are losing their soot coating and
returning back to their old coloring -- and so are the moths. This
example is well-documented.
This proves only that species have the ability to adapt to their
environment, and that birds could more easily see and therefore prey upon
lighter colored moths, not that they have the ability to change from one
species into another. Those moths are still the same species of moth,
regardless of what color they are. They did not become something more than
moths.
