Has anyone ever just stopped and thought, MAYBE, what the Regular drone picks up from a human host, is INTELLECT? the abillity to manipulate and decieve? I think the PredAlien Queen theory actually makes sense, in the fact that it was at a point where it wasnt fully developed, but was in a situation where it NEEDED to make a hive (Based on the fact, that it would have developed in the ship, had it not crashed into the damn planet) This gave it a hormonal instinct, to find hosts and throat**** them. It went into an emergency state. As for the dreadlocks, I believe that this physical aspect on predators may be something as simple as Wisdom Teeth. Everyone is born with them, but we dont have a real purpose for them. Or maybe it is something in predators that we dont understand, that hasnt fully been explained via movie? The Predalien took an aspect from the Predator, and some instinct, just like a drone would from the humans. And for those that would make the argument, "What does a drone take from a human physically?" I would have to say, Nothing. Maybe no physical aspect taken from humans would have made them better. Maybe that is how the genetics thing works, Maybe the alien only takes genetics from its host that will improve it. Maybe the dreds are a source of power, or hearing ,or some sense.
