Why did the men and women in Vandread split up to begin with?


I don't know if I'm just misremembering what I saw in the anime, or if there
really was no good explanation ever given, but I am unclear on the real reason
why the original men and women in the space colony in Vandread split up into
two separate colonies in the first place.

So, **do we ever get a real explanation as to why they split by gender, or is
it just something we're supposed to take for granted?**




> Once upon a time, in the future (roughly two thousand years from now), a
> colonist ship departed Earth, heading for the stars on it's journey to
> discover a new world to populate for the human race. This journey proved
> successful with the discovery of not one but two neighbouring planets
> suitable of colonisation. However, the colonists grew into conflict with
> each other - A conflict that divided the crew by gender! The men settled on
> one planet, which was dubbed Taraaku while the woman settled for the
> neighbouring planet, Mejarru.

I couldn't find much to support this but it sounds like something that fits
the anime.
