Language also has a lot to do with what we do. We do more complex things than animals, so we say more complex things than animals. The biggest difference in the evolution of human language versus the evolution of elephant language might just be that we have thumbs.

Birds have areas of the brain that we would consider language alike. Both for native bird communication and I would also speculate that for human to bird communication.
If you have ever owned a parrot this is blatantly obvious since they actively communicate and vocalize both observations and needs/desires
One thing I've learned by following a link from elsewhere in this thread is that while the total count of neurons in an animal's nervous system is not a good proxy for intelligence, the count of neurons in the forebrain is. By that measure, only the orca ranks higher than humans [1].
That doesn't mean language ability is a natural outcome of crossing a certain threshold of brain complexity; if anything it's more likely the other way around: this complexity being be driven by highly social behavior and communication.
