Natural Selection

Natural Selection, introduced by Darwin in the 1850s, can be defined as the process where certain traits make it more likely an organism will survive long enough to reproduce; it's a key mechanism of evolution and one that was not supported last week when a few young men went off trail in order to pee on Old Faithful http://www.huffingtonpost.com/2009/05/14/2-yellowstone-workers-fir_n_203770.html. When have you ever had to pee so bad you were willing to risk falling through the earth's crust to a scalding death...and do it all on camera. I'm just not sure that the outcome supports natural selection.
