The Thing in the Attic depicts a very successful seeding project (humans are modified to live in various alien environments). It tells the story of a small group of intellectuals from a primitive culture of modified monkey-like humans living in the trees of their jungle world. Having openly voiced the opinion that the godly giants do not literally exist as put down in the book of laws, they are banished from the treetops for heresy. In their exile on the ground they have to adapt to vastly different circumstances, fight monsters resembling dinosaurs, and finally happen upon the godly giants—who turn out to be human scientists who have just arrived on the world to monitor the progress of the local adapted humans. The protagonists are told by the scientists that their whole race must eventually leave the treetops to conquer their world and that they have become pioneers of some sort for accomplishing survival.
