Precursors made the powder that the humans and Shan'Shyuum used on their pets that had some sort of endearing effect (I don't recall exactly what it was initially). The pets eventually evolved into the flood (it was actually quite interesting the various steps from the pet to the flood...it would do some good to get a copy of Halo: Cryptum for yourself)
