Humans

[Mizu Kitsune]

humans are weak fragile creatures. however, we are strong not just in intelligence, but in imagination, belief, and will power. those 3 things are the key to accessing the celestial archives and be granted entire knowledge. that and a basic knowledge of psionics.

Heh, even if one had access to a celestial archive, people would make as much use of it as they do their local library .

Kangaroo's jump. But still, I never said anything about walking bipedally. I said I wanted a tail. I fully believe even creatures walking/jumping/swimming on two legs can exist easy. Dinosaurs had two legs and many of them had both tails and ran bipedally, no problems there.

Just because something like that doesn't exist doesn't mean it can't. However, the fun things is that we DO have a tail at one point of our creation. When we're still a fetus we do develop a tail. But the older the fetus gets the tail gets absorbed and eventually fully disappears. There have been people born with tails as well. Some tails are just skin and nothing more, you can't move it or anything, it just hangs. Other people actually develop bones in their tails and makes them able to move it.

God I wish I had a tail. O good one and all, like cats. Or as strong as Kangaroos. Or have a cat tail but it's as strong as Kangaroos, that would be the best. ^_^

Just not with tails.

Dinosaurs had two legs and many of them had both tails and ran bipedally, no problems there.

Except the extinction thing, with their only living descendents being tailess bipeds (birds).

But you are a skilled enough character modeler and animator are you not? So there is really nothing to stop you from bringing your perfect, tail augmented self into the world of Nexuiz to dominate with your highly balanced aerial acrobatics!

You can put the "ai" back in "tail".

Let me reform that: I fully believe even creatures walking/jumping/swimming on two legs and with a tail can easily exist.

Dinosaurs had two legs and many of them had both tails and ran bipedally, no problems there.

Except the extinction thing, with their only living descendents being tailess bipeds (birds).

Except the dinosaurs that walked on two legs and had a tail got extinct by a meteor. They didn't become extinct by natural selection. Thus making your view/theory in this case wrong.
Btw, birds to have a tail, just that it is feathers and not a 'actual' tail.

Some humans are born with a small tail, and we all have a vestigial tail in the form of a few fused tail vertebrae. I want a tail with bony spikes at the end. It'd be useful as a defence mechanism and a wifi antenna mast.

That's no excuse, along with us mammals, dinosaurs survived the greatest mass extinction, by that asteroid that hit near Australia probably. In fact that is what let them dominate, that asteroid killed saurosuchus and other pillar-erect legged reptiles, so that they could rise to the top (on land).

Then a much less devastating comet impact killed them, certainly because their size/shape class that carried them into the Triassic had been replaced by the tailess birds that had branched from it. There simply is no other explanation.

Tail feathers are not tails, they have no real weight and cannot be used for balancing or grabbing onto things. They're just feathers for flying and looking pretty.

That's no excuse

Um, yes it is. Getting extinct by outer means other than natural selection is anything but natural. Thus, it doesn't matter what kind of creature you are, no matter how 'superior' or inferior you are, you still will die.

If such a comet would strike us now and kill all humans and most of the life on this planet, then who's to say that bipedal tailed beings couldn't arise? Or are you saying that under no circumstances such creatures can exist whatsoever? If so, that's blind and inaccurate thinking.
Bipedal tailed dinosaurs are a great example that they can. If they were to get extinct by natural selection then I might have thought differently, but this isn't the case. In fact, they pretty much dominated over other species (don't take this for granted, I haven't read dinosaur history in a long time, but from what I can remember ). T-Rex and Velociraptors where the main superiors to others.

The event at the end of the Triassic was nowhere near the greatest mass extinction. That was at the end of the Permian, and almost sterilized the planet ( around 80-90 % of all life exterminated). And it wasn't caused by an asteroid.

By the way, dinosaurs (and archosaurian reptiles) were much more diverse than mammals and they dominated the planet for some 200 million years. And not all of them were bipedal, like ceratopsians, sauropodas, stegosaurians (they had a nice spiky tail) etc. And birds just mutant tailless velociraptors with wings.

Yeah I heard that too on a documentary from a while back... called Jurassic Place or something. T-Rex ruled and ate Ornithomimosaurus and Ibex populations while Velociraptors were so big and mean that they could eat people and they fed on little turkey-sized Deinonychus and Aurochs.

No you misunderstand, I was talking about the Permian extinction, both mammals and dinosaurs lived before and survived the Permian extinction. But then only the former survived past the Cretaceous extinction.
