As many of you know, I have pushed DNA studies for some time to establish relationships between mollusks. I do that as if I really understood what I was talking about. The OJ case showed that there are DNA differences between creatures of the same species. What I want to know is if DNA studies can also tell which species are closely related, and if species separated by geography but which look alike are truly the same or different species. It occurs to me that in our present technological age, we should be using something other than outside looks to establish relationships. Are any museums equiped to do these examinations? What's it cost? Should we be putting new names on things when there is still a chance the "thing" already has a name? Your humble Question Man
