I think with the Xenomorph and its Evolution you are left with TWO ways to go.
1) A Natural Evolution, the Xenomorph could be a Species that has a RAPID kind of Evolution and Adaption, and so WHO KNOWS as to HOW FAR and FAST they could Evolve..... 8000+ Years ago Mankind was living in Caves with simple Stone Tools.... we had LIVED this way for 10's of Thousands of Years. before we Gradually Evolved through Various AGES until we saw a RAPID EVOLUTION as FAR as Technologically in the Last 200 Years.
But i am talking about Knowledge/Technology etc as Opposed to a Physical Evolution. So how we got from Stone Age to Space Age took a LONG TIME.. could the Xenomorph be able to Progress at a Faster Pace?
But then you can also look at Genetically/Physically as far as Evolution too.
A Human has NOT changed much over 10's of Thousands of Years..... we may Change so Little in Thousands of Years Time...... NATURALLY.
But i think if we saw Humans in 3000 Years we may look Very Different as i think we would EVOLVE ourselves in a Artificial Way..... which brings us too.
2) Artificial/Engineered Evolution.... the Xenomorph becomes Evolved via Experimentation and a HUBRIS in doing such a thing..... this KIND of Hubris is what we see with the Planet of the Apes Plot.....
The Plot to TIE in a Xenomorph to Synthetics/A.I is ONE that has Disappointed a Number of Fans... but it makes Sense..... if Synthetics become Sentient, then using the Xenomorph and Evolving it to become a KILLING MACHINE to USE on Humans make Sense... because the Xenomorph requires Humans as Hosts, so it would HAVE NO Interest in Harming a Synthetic unless they GET in the WAY.
There is a PROBLEM with Evolving the Xenomorph though....
While it may be Limited as it is.... i think you have to be CAREFUL as to HOW MUCH you go and Evolve them.
The Xenomorph has NO MORALS it just SURVIVES like a Insect, Spider etc it has the Instinct to Survive and Procreate..... a BASIC INSTINCT.
To EVOLVE them where they then Speak to Each other... would be a Mistake they should RELY on a Telepathic Communication..... we dont need any JERRY'S LOL
To have them Building Space Ships and the LIKE would maybe make them become just a Star-Ship Troopers with Xenomorphs... this could LOOK like the Warhammer Tyranids... but would this WORK?
Having them EVOLVE to ADAPT to their Environment and Methods of Procreation i think is DEFINITELY something we should Expect the Organism to be able to do.
I think when looking at BOTH KINDS of Evolution you have to ASK the Questions.
A) What is the Xenomorphs END GAME/AGENDA?
B) What would be the END GAME/AGENDA of anyone who wants to Experiment/Re-Engineer the Xenomorph?
Because the Answer to these SHOULD then FORM as to HOW the Xenomorph would/could Evolve.
