Similar, but not the same. Quill's spikes are quills like that of a porcupine, while Spyke's are bone shards pulled from his skin, the same as the comic character Marrow.
In Evolution he was Storm's nephew and was created because producers felt the team needed more racial diversity. Why they didn't just use an existing black character, we'll never know.
The X3 Spyke bears little resemblance in appearance to the Evolution Spyke, but his powers appear to be the same.
In Evolution Spyke joined the Morlocks after his mutancy evoloved to give him a bone armor of sorts and the ability to ignite the ends of his spikes.
