The four beasts, lion, bear, leopard, and the 4th beast with ten horns, are separate entities in Daniel 7, whereas in Revelation 13 they are all joined together as one, the one world order. As such, the four beasts can be recognized representing all the world's nations as the four leading, but different type socio economic systems. Another assessment that can be made from the four beasts in Daniel 7 that are diverse from each other, and therefore not unified yet as they are in Revelation 13, is that the four horsemen in Revelation 6 who also are different in their agendas from each other, would correspond to the chaotic world prior to their unification.
Daniel 7:3 And four great beasts came up from the sea, diverse one from another.
