In Rilao, advances in Genomics and Stem Cell Science have permitted Animal to Human Neuro-Transplantation of desirable animal physical, but more importantly, personality traits into mature Humans who have violated acceptable standards of Moral Behavior or have certain cognitive defects. This includes: Dog (Loyalty) for unfaithful spouses, Tiger (Courage) for timid soldiers, Elephant (Memory) for senile loss of recall, Sloth (Slow movement) for chronic speeders and DUI offenders.
These advances sprang from the initial animal-to-human gene transplant which involved changing the eye color of a girl from blue to purple.
