On another planet, far from Earth, life took a similar path, but with a different result. It was Apes that became the dominant species and man remained Neanderthal like in small packs, kept in zoos, and found in the wild.
Simia is the home planet of the apes and three major species have developed both socially and scientifically. With that
knowledge they left the bounds of Simia and began to explore the stars. A team of humans astronauts crashed on a planet colonized by Simians and history changed for both species forever.
