  1. I need to know how the arms would evolve further. Like if the Trex lived for another era, would it's arms disappear completely? Or become wings?

  2. Yes!!! I asked this question: If the T-Rex lived for many more millions of years, would the arms disappear completely? Because, if the answer is *yes*, it means the arms were useless. But if the answer is *no*, then it means the T-Rex had a good reason for using it's arms.
