I completely agree. Just look at MRSA.
I always think about that scene in "Jurassic Park" when it is discovered that the same-sex dinosaurs were reproducing, and Jeff Goldblum's character says "Life will find a way." Fiction, yes, but it's not a stretch. In the 14 months since the Japan earthquake and Fukushima nuclear power plant catastrophe, butterflies have already mutated.
It's not hard to see how life adapts and finds a way.
