Thanks Alneyan...I was thinking if I wanted to have 2 species temporarily just for reproduction rates, while awaiting a large transport arrival with the proper final species from a long distance.

So if a planet has atmosphere "none"...and has 2 species, dominated by Oxygen breathers, it would TForm to Oxygen...and if I dropped Methane breathers on it Last second, before the actual "upgrade", the program would decide on Methane even though the species dominance was many turns less...is that the gist of it? (Hope that makes sense).

Another question: I've noticed a species creating new Planets (!) in his homeworld system. I'm assuming these are created from Asteroids...what tech level/family does this ability come from?
