No there isn't. Mutations are random.

The odds of two people throwing a dice 10 times and getting exactly the same result are (1/6)^10. Pretty low.

"No, there isn't mutations are random"

Ok Well obviously they must have some mutations in common. It would be quite bizarre that it just so happened to be the case that the one group of fruit flies that can adapt to survive in the dark were the ones picked for the experiment I linked.

You must be wrong about that.

Regarding dices I never said anything about the exact same results.

Mutations are random but environmental stress can increase the mutation rate in Bacteria and Plants (not sure about animals). There's a scientist called James Shapiro who's written books about how genomes evolve , I think he calls it Natural Genetic Engineering. The central thesis is that genome evolution is induced by environmental stress.
