Interesting. What's the difference between a mutation and a variation?
For example, is there a methodological difference between the genetic differentiation that causes different hair colours, and the genetic differentiation that results in different numbers of toes?

I had heard somewhere before that the estimate was 150 mutations on the average. Of course, the total number would be greater than that, because people commonly live far beyond reproduction age. This is an average for germ cell mutations passed on to offspring.
Of course, inasmuch as the 95% of our dna is junk, only perhaps 7 or so are effective mutations to actual functionality.
Twiler: at the level of the genome, there is no difference. However, the dna is not the only determinant of variation; there is also methylation and wrapping on the histones octomeres (known as epigenetics), which effect genes begin copyable to tRNA or not.

I don't think we're all mutants. Quite a few of us are spuds.
