Good science fiction premise. The presence of the Moon and its stabilizing effect on our planet's climate, the presence of Jupiter with just the right mass to have a stabilizing effect on bombardment while not destabilizing planetary orbits, and then the presence of a primordial black hole allowing the monkeys to study dark matter physics once they reach space. Almost like it was an experimental setup.
