> Now isn't it all clear? Yes, actually, now I do understand! However, I have one more question. With the advent of new techniques to classify plants and animals, why is the scientific community holding on to 300 year old rules for naming convention? They don't have problems using new technology and techniques... so why not adopt new rules for naming? We could even let the commercial business world get involved. For example, what teenage kid wouldn't want to grow some Iris brittany-spearsensis in their garden instead of the old fashioned Iris foetiddisma?! Yes... of course I'm joking. LOL!
