'All organisms', period?
seems like this isn't the place to argue that every organism in existence is on earth right now. we shouldn't use "all currently living organisms" to refer to the descendants of the LUA unless we're also going to say that there aren't any currently living organisms unrelated to life on earth. —The preceding unsigned comment was added by Special:Contributions/ (talk)

Along those same lines, perhaps drop the "living" as in the LUA being the "latest living organism?" Tom Schmal 15:35, 31 October 2007 (UTC)

To those who are mentioning Extra-Terrestrials
Other biospheres would presumably have their own respective LUCAs and LUCA heritages, and since we live in a very young universe that is still mostly hydrogen with which to fuel future stars, a much newer biosphere even in the same universe (as opposed to a parallel one) might be developing in the LUCA phase of its evolution right now.
