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.
