Though I don't wholly reject the idea that parallel evolution could result in a creature vaguely similar to humans I'm definitely more interested in pushing the limits of what life forms are conceivable.
I find your hypothetical creature fascinating. Have you thought of featuring it in a work of fiction or paying an artist to produce more detailed renderings?
I generally get more enjoyment out of writing non-fiction. I more often scratch that other creative storytelling itch with tabletop RPGs. That said, it might be fun to run an art contest for the Graxians, which is something I haven't tried on Steemit. Thanks for the idea.
