Myth Weaver
The examples you list may result in other species evolving into something similar to humans
May also evolve into humans, which is all that is needed to explain the OP's question. The probability is that they may be something similar to humans but not exactly the same, I simply point out the probability is slightly higher than anything else that they will. The evidence, so far, would support my claim
Since the OP is talking about a world with humans, I would assume carbon based life forms are the given, and a world similar to our own.
If the author wishes a world with creatures almost, but not quite, human, but in story respects are the same, may as well go with humans. The readers wont get turned away just because of that.
