I don't see why it wouldn't be. Bear in mind that simply because we can't see the connections doesn't mean they never existed - it's possible that one world (or perhaps several worlds) in between were destroyed by something or other, or for whatever reason simply ceased to exist. Humanity, or whatever the dominant species that existed there was, may have destroyed itself; for a myriad reason, the world may have been rendered insensate. But that world would have variations on itself, some of which may have survived, and evolved beyond that which would be recognizable immediately without tracing the link back.
To use your own example, several of the animals here can communicate with us via telepathic brainwaves, and some of them can be taught to utter human speech; many of them are more intelligent than most people. With that in mind, does this world being connected to a world with speaking sentient ponies sound that impossible?
