Yeah. The only reason I could think of that we didn't see any pregnant elves (if that happens) in LOTR is maybe because the elves knew that their time was almost up on middle earth so they were waiting...? Anyway, this totally doesn't answer your question but its just a thought.
Also, did you all know that orcs are corrupted elves (generally known) and that trolls are corrupted ents(less known)?
I do known, however, that elves are reincarnated after they die. But possibly not on middle earth?
they go to valinor, the undying lands, and live there, men also have an after life, but none save for illuvatar know of it,
i knew about the orc and troll thing, i learned of trolls by treebeard,
if orcs are corrupted elves right, they would have had to catch elves and mutate them, well in the case of trolls and ents, is this the entwifes fate of which no-one knows
trolls are not corrupted ents, people...
trolls were corrupted by melkor (i think) from some naturally occuring middle earth dumb brute animal, in IMITATION of the ents, so that the bad guys cud have a giant warrior in their arsenal, too, tho the trolls are compared to the ents as the orcs are compared to the elves in terms of strength etc.
well forsure trolls arent from the entwives since trolls were in existence long before the entwives disappeared. as for the origins of trolls, yes they were made in mockery of ents, but from what? well it says that melkor cant create something wholy new so he would need something to start with, so one could assume he started with an ent. But then theres the issue of dragons, they seem to be pretty well independent and created with no starting refrence, i.e. orcs from elves. Tuff Question. my guess would be that he didnt use a ent and corrupted it as he did of elves, but perhaps he knew of the ents existences and from that knowledge he created trolls.
also, there have been many elf children through out the histories for instance arwen had to be a child at some point, but i think i read somewhere that they are so alike to human children that they can easily be mistaken, but they mature more slowly. I agree with the point that someone else made when they said that the elves of LOTR are probably waiting to see what happens, perhaps because they dont want to bring a child into middle earth the way it is.
Um...in my odd opinion in this thread... Young Elves are like human children when they are young, but they take a long time to mature and all that hence how long elves really live without slaughter. I believe, and this I'm not sure, but I think the young elves are considered at adulthood when they live to 200 - 500 years old.
What Turin said about the troll's creation from the thought of Ents was right. Elrond is about I estimate, around 3,500 years old, because he has fought in the Last Alliance, You have to think that since Elrond married Celebrian then that makes Galadriel much much much older, because in the Silmarillion, they said something about how Arwen considers Galadriel her great grandmother, I don't remember exactly, this might be wrong.
Well that's a bit off topic so now I'll take my leave.
