In this thread, let's talk about evolution. Specifically, future evolution of various animals.
I want to focus mostly on evolution sans notre aide; that is, without our assistance. We've long discussed how humans may evolve in the future— whether that leads to us looking like Grays, diverging into Eloi and Morlocks, adapting to new planets, and whatnot.
But what about other animals? What will they look like in 50,000, 100,000, 1,000,000+ years' time?
The most obvious set of animals to start with are canines, felines, and primates.
For the sans notre aid scenario, let's assume humans are forever locked at a near-future level of sci-tech development.
Dogs today descended from wolves. We don't know what species of wolf that was, but it happened several dozen thousand years ago, and their evolution would have taken wholly different paths had humans not discovered how loyal, intelligent, and downright useful they could be if only they could be tamed.
Fast forward to 2017 AD, and there are dozens of breeds of dogs. However, despite our eugenicist attitude towards dog breeding, no one has yet managed to create a new species of canine.
What would it take? We could keep breeding and breeding them until, eventually, a subspecies emerges. However, that still isn't a new species. Speciation in long-lived mammals takes thousands of years at least, and that's including artificial selection.
So let's fast forward again to 150,000 AD. Humans are comfortably spread about, but we're most populous on Earth, Luna, and Mars. Lo and behold, that's where dogs are most populous as well.
So how about it? What do you think dogs roughly 150,000 years from now will look like, taking into consideration that they can be found on Earth and elsewhere?
