The Halos only kill sentient life, maybe the primates weren't sentient. Probably wrong, I suck at biology.

While many religions and belief systems ascribe sentience to nonhuman life, the majority of the belief systems in English-speaking countries (clearly the target audience) do not. As a result, the use of the term sentience in the cannon as it describes the action of the Halo ring firing would exclude all life on Earth (except, of course, humans).
So in a less wordy way, the reason these "pre-humans" are around is that they were unaffected by the firing of the Halo rings, and evolution can still hold true in the Halo Universe. Hooray.Mmmm...not entirely. Sentience is defined in a variety of different ways (I like the definition that, in order to be sentient, you have to be aware of your own existence) but is ultimately irrelevant here. The Halo effect effected everything with neurons; with the reasoning that any sentient being (that the Flood could subsist on) would have neurons (and thus a brain) which would be destroyed by the rings. Needless to say, most life on Earth and the galaxy (which wasn't protected) was destroyed.
In regards to the overall topic of this thread, evolution could still have occurred prior to the rings being fired and would have resulted in humanity. The humanity that was present when the rings were fired wasn't "pre-humanity" it was humanity in it's present form. Although we have yet to find out if the Forerunner altered us in any way while we were in their care...
