“Is that a problem?” Althea asked.
“Perhaps,” Kadeya replied. “Let me explain why I think so. We deployed RNA viruses designed to produce genetic variations that would increase the production of vesicular monoamine transporters in their central nervous systems.
“That single mutation dramatically enhanced intellectual functioning among the progeny of infected individuals. We observed measurable results within just three sapien generations. Physiological and behavioral changes among the hybridized sapiens were more profound and were occurring much faster than anyone had foreseen.
“Seeing that, our scientists began a second set of autopsies on preserved specimens from the first and second hybridized generations. When compared with the brains of non-hybridized sapiens, we found two signific
