I want to know the answer to the following question:
What animal was found, through DNA testing, to pre-date the arrival of humans to the archipelago?
All the background I'm provided with is that "Recently through genetic DNA studies, scientists have discovered that a species of turtle, the diamondback terrapin, previously thought to have been introduced, pre-dated the arrival of humans in the archipelago.". Is that enough to answer the question?
Answer: yes
