Evolution drives this story. If evolution can do all kinds of things, why not produce a man that has photosynthesis skin^?  It probable could not do such a thing, Only God can do that and rest is just Darwinian speculation._.

In John Scalzi's Hugo Award-nominated novel Old Man's War, soldiers are equipped with genetically engineered bodies that not only possess cybernetic brain implants and enhanced strength, speed, senses, endurance and dexterity, but also green, photosynthetic skin.
