Evolution Chamber

 
The Evolution Chamber is required before you can morph Creep Colonies into Spore Colony anti-air defenses. Otherwise, the Evolution Chamber is responsible for evolving upgrades for Zerg ground units. Zerglings and Ultralisks benefit greatly from melee attack upgrades, while Hydralisks become more potent with improved missile attack. All Zerg ground units become tougher from carapace upgrades, but make sure to evolve weapons upgrades first.
