What can't be backed up by evidence? What theory? Evolution? Please be more specific.
And humans did, in fact, evolve entirely due to necessity. While less intelligent beings died out, the intelligent humans survived and lived on to pass their genes to the next generation. Although that's not entirely why humans are intelligent today, it does show that to survive, you needed to be intelligent.
As for going from stone buildings to skyscrapers and such, that wasn't an increase in intelligence so much as society learning more about architecture.
I still think that evolution can happen outside of necessity. Dolphins come up with games to play using there blow holes to blow ring bubbles (like smoke rings but with air and under water). Different species play games to pass time, if they are intelligent enough to have the free time to play games, I'm sure they can adapt to things, not necessarily evolve, as you said, we didn't evolve just learned more about are planet, but look at primates, they are coming up with more adoptions, I'm not saying where on the brink of something, but it's a possibility.

I think that monkeys, gorillas, etc, could do the same with some thinking. We have very intelligent animals in this world. Crows among them. You may not believe this, but crows are one of the most intelligent birds on earth. And you're probably thinking: 'How in the world does that dumb thing even know where it's own nest is; let alone being intelligent?!' Well, I'll tell you.
Birds eat a variety of things. Including nuts. The crows will put the nut on the road. That's not all he's leaving behind... And when a car goes by, it cracks open the nut. The bird then eats the nut. I think multiple birds do this, but i think learning that the crows would do this fascinated me the most.
And for those of you that don't like raccoons getting in your trash, and you think they're just nasty creatures beyond belief, lemme tell you something you might not have known; raccoons are actually clean animals. You're thinking: 'Yeah, right. Liar!' I'm not lying. Raccoons will wash their food off before eating it. How cool is that?!
We are living among some of the worlds most intelligent animals. Us, on top. Or so we think...
I want what you all think about 2012. Is it fact or fiction? I highly doubt that the world will peril; didn't people say the same thing about the year 2000? And look at us now. 10 freakin' years later.
If you want to discuss this with people make your own topic please, this has been moved to general discussion and that would be changing the topic, thank you.
Birds are very smart creatures, very adaptable and hard working for themselves and there young. One of the smarter species even makes large nest with multiple other pairs of birds, sometimes even hundreds. But this is turning into more of an evolution and nature friendly topic, what do you all think would happen if there were other sentient species on this planet. What are your predictions? Warfare, peace, segregations, inter-species pairing and development? What if anything do you think would change.
Inter-species breeding could only produce children if the two species branched from the same genus. A species completely separate from humans would not be able to interbreed.
EDIT: I am being redundant, Yaaaaaaaaaaaaaay.
