I agree it doesn't on its own. I came up with the idea before I heard of the genetic idea. I had the idea to answer the where all the species came from and why the GalCop zones are exactly same sized rectangles (cuboids) of space. If you go with the genetic idea, which has plenty of merits (mind I do find the selezen's random seeding idea too artificial, but seeding based on the type of world found is more logical) we still need to explain a few things:
Sweet a challenge! fire away!
1) Humans at some point discover interstellar space flight and therefore would have colonised a spherical shell centred around Sol of which the Galaxy 1 is just a subset. (this fits in with everything I know of space outside of Galaxy 1)
So kind of like the old worlds then? Ok with you up to this point.
a) If Galactic Hyperdrive is known to all of Humanity and other species then there would be a shell of equal size to the one around Sol centred near and engulfing each of other galaxies, But we have no references to those worlds, and their relationship to GalCop and other organisations, where as we do for Galaxy 1. Surely they would either form their own agglomerations or be part of the existing GalFed etc.
b) If Galactic Hyperdrive is only available to GalCop Citizens (e.g. single source of production and made physically dangerous to reverse engineer and would have to have been developed/discovered after the formation of GalCop) then colonization would have expanded in each other Galaxy centred on that galaxy. This would mean that worlds outside of Galaxies 2 to 8 would be colonized by GalCop and therefore likely to be part of GalCop yet they don't appear on the map.[/quote]
Well there are a number of possibilities given what we know about the canon. We know there were 3 waves of exploration, the generation ships and the faster than light witch drives and the gal drive.
Generation ships probably didn't get very far or are still getting there, they'll be pretty much all in gal1 still.
Witch drives shrink things considerably. But only in a local group. As for invention there is still several issues of origination going on here. See below.
Gal drives now you see that's a tricky one because that's a 2 part system. It's like a motorway; the men who made the car didn't nessessarily make the road on which it travels. So far as far as I can see although the gal drive can access the routes, galcorp didn't make the road.
This begs the question did galcorp actually make the witch drive "roads" as well (if they even need roads)? If they didn't and they're just "riding the tube (and not telling anyone)" then this would happily explain why the sectors are a certain size. Maybe the routes accessible to galcorp are more expansive but they just go to dead systems or unpolice-able ones. No one wants a handy dandy system 1 ly from lave that separatists can construct a planet killer on then witch it over. It would be very embarrassing.
This fits with the Mutablis Raxxla, DarkWheel and Drews general postulations regarding the Galcorp exists on and profits off Hijacked high technology.
We have to accept the distasteful possibility that humanity is piggy backing off an elder race and is only exploring as far as they did, less even. It's like a pack of primates living on a cruse ship. Everything will be hunky dory until things start to go wrong.
This would explain the witch space routes are restricted. Given the methods and motives available to galcorp. The corporate body cannot progress because the existing accessible routes are unprofitable or further expansion is too expensive R&D wise.
2) After either scenario 1a) or 1b) you would have regions outside of each galaxy with Human Colonists in them. So why would the other species migrate out of Galaxy 1 to Galaxy 2 etc if they are persecuted. The other galaxies wouldn't be any better. I very much doubt humans would migrate back to Galaxy 1. Genocide would be a more logical explanation, not that I would like that.
If we can get around these issues great.
Not if Humanity or it's genetic brethren. Cannot get there.
Anyway just things to think about. I will admit we are suffering from "neat little box" syndrome here.
