@ccleaver:

Were the Twins Born Werewolves or Bitten? Ive heard mixed theories on this.

I checked the episodes to see if they hinted at it. Apart from the episode where Ethan and Aiden explain to Scott about how they killed the pack members and their Alpha, there is no other mention to their history.

But considering there is no strict canon, we can only assume that they were werewolves by birth due to the following reason:

They are identical twins (Biologically, they are two children that were born from the same egg containing similar genes). Considering they are the only werewolves who can combine to become one giant alpha, they would have achieved this power only if they were born werewolves, not werewolves formed from a bite.
