You're right - it isn't good to argue merely for the sake of it, but nor is it good to let error go unchallenged! I've done my utmost to convince you that your position on extinction is not logical, but I don't seem to be making much headway! We shall have to agree to differ, as this must be my last post for a while as I must do some real work to avoid financial extinction. However, I shall allow myself the luxury of firing a few parting shots before I go ...
(i) You are mixing up possibility and probability. It is possible but highly improbable that a million icebergs will arrive in Times Square. It is both possible and probable that species have become extinct in the past. To the vast majority of people, both specialist and non-specialist, it is more than probable, it is a demonstrable fact.
(ii) Your method for identifying species is not universal, since some organisms only reproduce asexually.
(iii) You claim that modern genetics discredits evolutionary theory, but in the New Scientist article you referred to in which various experts on molecular genetics express their opinion, the debate is only about the precise patterns in which genetic information has been distributed. There is no suggestion that evolution itself is discredited, nor that the history of life on earth was not characterised by constant change.
(Andrew - I think you will find that you need to refer to the latin name, rather than the common name, to determine the species!)
I must go. Goodbye.
