Cloning is a technology that can be researched at the Animal Nursery in Tech Level 4. It costs 250 Food and 250 Carbon, and makes animals in the nursery produce Food 50% faster than base rate. Genetics must be researched before it becomes available.
Like the previous technologies, Cloning will pay for itself with the increased food growth. If the player has Nerfs or Banthas in their nursery, this technology should be researched soon after reaching Tech Level 4.
"The rate at which food is generated at your Animal Nurseries is further enhanced by this Tech Level 4 technology."
