I would also hope Ridley does not directly contradict Alien (because how hard is it to keep the first story consistent).
He already did, in a way, with Prometheus.
The origin of the Xenomorph was a mystery during the Alien movies. We (well, I did) assumed the Engineer crafted the Facehuggers so they could find a suitable host when feeling endangered. When Kane got one attached to his face onboard the Derelict, we assumed the eggs had been placed there by the Engineer (Space Jockey) himself as some sort of weapon. The sole purpose of a Facehugger is to find a host and grow into the Xenomorph. Mind you, the Facehugger + host DNA = Xenomorph, but not the one's we see in Alien/Aliens. The Xenomorph in Alien 3 was different (depending on which cut - Facehugger Queen anyone?) and originated from a Rottweiler/Ox. Although it had the same skeleton, it was slightly different to the ones we had in Alien/Aliens. The unlucky Engineer who got hugged by the Trilobite had a different outcome. We got the Daecon.
Daecon = Engineer + Trilobite (thanks Hicks, forgot the name)
Xenomorph = Human (by Facehugger)
Predalien = Facehugger + Predator
It all depends on what type of creature attaches itself to the host.
We can add another variant after Alien Covenant
