There is no difference between Goblins and Orcs as far as being different species. They are basically the same. If I had to name one difference it would be that Goblins are a type of Orc that has developed more to tunnels and caves, whereas Orcs I think of more patrolling in open spaces, such as the plains of Gorgoroth.
The origin of Orcs is an open question. In Tolkien's writings, evil is not capable of independent creation, making it unlikely that the Vala Melkor, who was obviously the first to produce them, could do that ex nihilo.he origin of Orcs is an open question.
