<p>We thought at first that Appa, Momo, and the dragons were all extinct. But then Aang discovered a herd of sky bison after the war and they now live on that Air Temple Island off the coast of Republic City, starting to regrow their race. Momo was said on his page to be the last winged lemur, but he had to once have a family to give birth to him and maybe siblings, so we don't know if his race is coming back into existence; and even so, there are ring-tailed winged lemurs closely related to normal winged lemurs, also living on Air Temple Island. The last 2 dragons, Ran and Shaw, that Iroh didn't really kill were alive in the first show, but we don't know if they were the same gender and eventually died off in Legend of Korra or are eventually giving birth to more. So, do you think that
:
</p><p>1. The regular winged lemurs, like Momo, are actually not extinct and just not found yet?
</p><p>2. The ring-tailed winged lemurs are an "adaptation" or "evolution" of winged lemurs like Momo, so Momo's race isn't really "extinct" and just look different?
</p><p>3. The dragons are permanently extinct or not?
