Discuss: Do Bacteria Grow on Bars of Soap?

In this Naked Scientists Question and Answer show, we find out if bacteria will grow on a bar of soap, why bird poo is white and whether or not a moon can have its own moon.  Also, do sweeteners alter your metabolism and can we re-stock the oceans with farmed fish?  Plus, we explore the oily threat to Bluefin Tuna, a newly discovered way that blood vessels in the brain clear a blockage, how channels on Mars reveal secrets about the Martian climate, and why shape is essential for H. plyori - a gut bug associated with ulcers and cancer.  In Kitchen Science, Ben and Dave recreate a classic experiment to show that flames are hollow!

When you answered and discussed the question on genetic diversity I think you forgot an important issue on why genetic diversity is important: changes in the environment and/or the ecology. Such changes will likely be less detrimental for species with high genetic diversity than for species with low genetic diversity. The chance of survival of any species must be greater if there are enough (genetic) differences among the individuals so that not all of them react the same to the change.

Yes, indeed, I agree wholeheartedly; that's a very important point.
