The answer to that question is that Jacob has always been a Werewolf. He was supposed to be the pack leader.He was born a werewolf but have not yet found the trigger. According to the Quileute legends he turns into a werewolf simply because the "vampires" were near.It was in his blood and already apart of him other wise he wouldn't be the ere or Emphrian or that he was supposed to be the pack leader because of his heritage. The reason they decided to find the trigger was because of the vampires

Jacob Black

When I think of Jacob I think of a Big redbrow Shagy wolf.
He turns into a wolf.
Jacob Black is pert of the Quileut wolf pack/Indian tribe
actually Jacob is not a wolf coyote or a werewolf because his ancestors of his tribe were shape shifters and they turned into a wolf at first so that is the only thing the members of the tribe in the move could turn into a wolf.
The main wolf is Taylor Lautner. In the book and movie his name is Jacob Black.
Taylor Lautner plays Jacob Black.
