From the article:
----------------------------------
Saying that evolution is a theory is like saying that the earth revolving
around the sun is a theory. Or that plate tectonics (continental drift) is
a theory. Or that the idea of atoms making up our world is a theory. Just
because such scientific elements are not apparent to the human eye doesn’t
mean they aren’t factual.
Evolution is a fact. It simply happens that because it involves time
periods spanning hundreds or thousands of generations, evolutionary change
is often much too slow for humans to perceive.
In some cases, however, natural selection does occur quickly enough for us
to perceive. Through mutations, new strains of antidote-resistant viruses
are always emerging. The same holds true for pesticide-resistant insects.
There is also the famous example of the peppered moth near Manchester,
England. Starting out with light-colored wings, they were camouflaged as
they rested on tree trunks of the same color. But, as industrial pollution
made the trees dark, birds picked off the lighter-colored moths. Mutant
moths born with black wings survived, reproduced, and multiplied.
