If evolution is really true then why isn't there more half and half creatures...such as half dogs/horses? Wouldn't evolution move in a straight line such as germs - mice - dogs - monkeys - humans instead of like fish - dogs - birds - cactuses - trees - monkeys - humans. Also why isn't there any animals more evolved then us. I know it takes supposively billions of years to evolve but still there would be something slightly more evolved.
