I'm well aware of horizontal gene transfer, but thanks for linking it anyways for the people who don't know. Edit: My response was lacking, apologies. AFAIK, there's never been a horizontal gene transfer from a prokaryote/eukaryote/any other kingdom to a mammal or animal. The last time may be when we got mitocondria.

Also, we seem to have quite a bit of bacterial and virus DNA that somehow got incorporated.
Oh, and it's mitochondria.
