LOST LEMURIA?
Harlan Ellison has created a deep background for the alien race known as the Kyben, as seen in "Demon With A Glass Hand". But all we know of them is limited to just that episode of 'The Outer Limits'.
So, looking at it only from the TV point of view, without the graphic novels and short stories, I'd like to provide a little more for the Toobworld background.....
As established in "The Chase", an episode of 'Star Trek: The Next Generation', the Preservers seeded many planets with the building blocks to create humanoid races throughout the universe. They didn't all look human, but they did share the same basic structure. This would include Vulcans/Romulans, Klingons, Cardassians, Minbari, perhaps the Centaurans, and Orkans.
And to this list we can include the Kyben of Kyba.
The Kyben may have developed along an evolutionary path with primate origins, as Darwin suggested in regards to the human race. But on Kyba, that path may have originated with a different species, perhaps something similar to our own lemurs. And since we never got to see any proof otherwise, it could be the Kyben still had some vestigial remnant of their own ancestors' striped tail.
Just a suggestion, Mr. Ellison. Please don't sue me......
BCnU!
