*blinks* I was almost about to post about the difference between
Lamarkian and Darwinian evolution until it was cleared up by the later
poster.
But, for the fun of it, the example of Lamarkian evolution would be
that the giraffe's neck grew longer because it stretched it to reach
higher leaves and then it's children would inherit that advantage.
Obviously due to those wacky tiny things known as genes, this
evolutionary theory is invalid (hey how about that, we showed an
evolutionary theory invalid *coughs*).
Anyway, Darwinian evolution, as I understand it, relies much more on
natural selection, much as the story of the moths above demonstrates.
In fact, this moth story (that and the canaries in the...gelopegoes(?)
islands) are the usual example(s) of natural selection.
