this is related to the sedimentation coefficient (Svedberg units) in centrifugation. It is related to shape, weigth and so on.

This explanation is correct for the name, 16S refer to the sedimentation constant of the small subunit of the bacterial ribosome,but this is constant between species.

As for the role in speciation see my answer in the other thread you started. And this is why you should not double post. Makes it harder to track your answers.
