I haven't read the topic yet but I'd like to point out that Fairies are not descended from humans:
[Pink Fairy]
We fairies are born from the morning
dewdrops of an aged tree.
The large tree that stands in the
center is like our '"Fairy Godmother."'
This type of trees probably originates from the Reptite Dimension (or FATE?), which would explains why there's no Fairies in CT.
Good point. But to counter that, the quote doesn't say anything about how fairies
evolved, just how they are born (similarly, saying that humans pop out of their mother's bodies says nothing about how they evolved either). Now one might have an objection to plants (the trees that produce fairies) evolving from humans, as that crosses Kingdoms, but to be fair, one might also have an objection to plants producing animals, or animals dying to produce plants. I would be very interested to know if any of the creators were familiar with the
Pequeninos (which, like the fairies, are born from a plant and return to plant form on their death) or OSC's works in general.
In turn, it seems quite unlikely that dew alone produces the Fairies. They seem to be complex creatures; one needs more than just hydrogen and oxygen to create such a creature (a heavy infusion of carbon, for example, would go a long way to making this physically possible). This might be the result of some sort of magic, but the Fairies don't seem to posses any magic abilities or associations otherwise.
Of course, there is no reason to believe that the Pink Fairy was stating fact as opposed to myth. Humans might say that they are born when a stork drops a baby down a chimney, or when parents go to a cabbage patch and pick one out.
Still, I quite agree that in all likelihood the Fairies (and the Dwarves) came from the Dragonian Dimension.
