I want to know the answer to the following question:
Where does Hamp say the Pontic Indo-European languages originate?
All the background I'm provided with is that "Eric P. Hamp in his 2012 Indo-European family tree, groups the Armenian language along with Greek and Ancient Macedonian ("Helleno-Macedonian") in the Pontic Indo-European (also called Helleno-Armenian) subgroup.". Is that enough to answer the question?
Answer: no
