I get the impression it's supposed to be realistic cloning, not traditional sci-fi cloning.
Born a baby, no memories.
Hey, you got a better way to rebuild a species in a hurry?
It makes perfect sense.
And that DOES make sense? There were so many zentradi ships you couldn't see through the cloud.
I'm suprised they weren't shooting EACH OTHER while bombarding the planet. The odds of any signifigant population of humans surviving were pretty slim.
According to Macross Compendium, the survivors were either off-planet or in well-fortified areas(namely the incomplete Grand Cannons). Which makes sense given the scale of the bombardment.
Is it just me or did the Grand Cannon totally kick some? I think it was underrated in the series. Minmay and the the Macross didn't win Space War I by themselves, it was also largely due to the awesome Grand Cannon.
