Then that must be a bug. I can look into it, but if you want to beat me to it, you might check out FloatVectorSpecies.

Stepping through the debugger with the following mutation parameters, I can watch DoubleVectorIndividual.gaussianMutation() as it samples from a std of 0.1 when mutation gene 0. I would have expected it to scale the std to be 0.0001 or such.
