Lizard Herders

A lizard herder scans the world with blank eyes as his stock grow stronger and smarter. The future does not seem to belong to him.

They were the lucky ones. Instead of unrecognizably distorting them as they had done to most of their subjects, the Qu had merely erased their sentience and stunted the development of their brains.

Distantly resembling their ancient forebears on Earth, the primitives led feral lives for an unnaturally long time. They never regained sentience after the Qu left, despite having every incentive to do so. This was partially due to the total absence of predators on their garden world, resulting in no advantage for intelligence. Furthermore, the Qu had made some small but integral changes to their brains, tweaking with the structure of cerebellum so that certain features associated with heuristic learning could never emerge again. Once again, the reasons for these baffling changes remained known only to the Qu.

The dumb people eventually settled in a symbiosis with some of the other creatures that inhabited their planet. They began to instinctively "farm" some of the large, herbivorous reptiles, ancestors of which were brought from Earth as pets.

Soon the balance of this mutualism began to tip in the reptiles' favor. The tropical climate of the planet gave them an inherent advantage, and they underwent a spectacular radiation of different species. They encountered no competition from the only large mammals on the planet; the brain-neutered descendants of the starfarers. Faced with a reptilian turnover, the only adaptation the sub-men could muster was to slip quietly into bestial oblivion.
