The Evolution of the Deacon. Links to the Xenomorph Alien?

There's many theories about what happens to the Deacon when it grows up. In [b]Prometheus[/b], we see the Deacon in juvenile form. But already we notice it is much larger and deadlier than the Chestburster we've witnessed in previous Alien films. So the question here is what happens to the Deacon when it grows up? Personally, I think the Deacon has nothing to do with the classic Xenomorph we see in Alien, Aliens, etc... I think the Deacon is something deadlier and something bigger. However, some fans think the Deacon is the first step in the evolution of the Xenomorph. This sketch found on [i]DeviantArt[/i] depicts one fan's idea about how the Deacon could evolve and mutate into the Xenoomorph we're more familiar with: [center] [img]http://fc02.deviantart.net/fs70/i/2012/179/6/0/aliens__xenomorph_evolution_by_hellraptor-d5588ih.jpg[/img] [/center] But then, we have questions about the Mural seen in the Ampule Room. It clearly depicts the Xenomorph. Some think it depicts the Queen Alien. Regardless of what "version" of Xenomorph it represents, it means the Xenomorph has been around long enough, prior to the introduction of the Deacon.

If you ask me, I'd say the Deacon is not linked to the Xenomorph. I think it's an "upgraded" version of the deadly organism which clearly inspired the Engineers on LV_223. But is the Deacon a first step into creating the [i]ALIEN[/i]? I'm gonna say no. I think the Xenomorph has been around longer than the Engineers themselves. I've mentioned this before - I think the Engineers tailored their technology around the bio-structure of the Xenomorph organism. I do not think the Xenomorph is non-existent prior to the Deacon's birth. But that's my opinion, what do you all think?
