Maybe. But it remains true that all extant life forms run on a common "life architecture" (identical 4 DNA bases, 20 amino acids, use of RNA, common energy usage, etc). One might suggest that there is "only one" successful model that has shown up for any number of reasons. One hypothesis is that there really is only one model, so if it shows up again, we would not notice it as "new".
But it appears true that no other superior building blocks have arrived on the scene in 3.5 billion years.
