If a brown dwarf orbited the Sun at the same distance as Jupiter, would life have evolved on Earth?

Computer simulations suggest that if a more massive object, like a brown dwarf (which contains the mass of dozens of Jupiters), orbited the Sun instead of Jupiter, it would have been harder for Earth and the other terrestrial planets (Mars, Venus, and Mercury) to have formed. So under these circumstances, there might not even be an Earth.
