As evidence for this, I'll use a few lyrics from Versus, which has been confirmed by Sparkles* to be about wars between interdimensional gods. I also believe it is sang by someone on either side of the war.
We adapt, mutilate, replicate and survive We adapt, we mutate, replicate and divide
They adapt (evolve), mutilate (injure/disfigure), replicate (reproduce), and survive (win the war?).
They also replicate and divide, like cells that split in order to reproduce.
Can you remember what it is we’re dying for? Fighting for?
The war has raged on for so long that neither side knows why they started it, but they know they must keep evolving and fighting.
