I'll give you an answer based on how I define the word "soul". My definition of a soul involves an animal that has obtained sentience. Any animal that has a brain has a "mind". The brain is the physical object, and the "mind" is the patterns represented in the brain that direct the animal how to respond to external stimuli. So, a "mind" could consist only of instinctual responses to the environment.
But, along with sentience and a free will comes the higher state of the "soul". It is still patterns represented in the brain, and hence rooted in the physical. The soul never separates from the body.
So, could animals other than humans have souls? By my definition it's possible. Maybe some apes do. I've not studied it enough, and I remain skeptical that it is anything more than sophisticated mimickry. But, still, it's possible.
The spirit, then, is nonphysical. And, as I said earlier, a body may be without a spirit. Apes definitely do not have spirits. People may or may not depending on the situation.
My final disclaimer: Though I'm a Christian, I don't claim that my definitions are "biblical" definitions of the words. It is simply the framework that helped me think through certain issues.
That should be enough fodder for a lively discussion.
