@Englander many years ago (close to 20), right when the superhots were just gaining traction, I posted a very long thread on GardenWeb about the Bhut Jolokia, Ghost, Trinidad 7-pot, Trinidad Scorpion, etc. all having a lineage that traces from Trinidad back to a single type of pepper in India, with the only real changes being slight epigenetic (mostly morphological) changes as a response to a change in the growing environment. I wish I could access that old post because it might be of interest to you. I'll check out the article.
Edited to add: I checked out the article-very interesting! Thank you for sharing.
