T origins in India

[SultanCaesar]

What are the historical origins of T in India? When and how did it enter India? It's pretty clear for haplogroups such as R1a and its subclades but I was curious about T and its subclades. It shows up in higher frequencies in the West Bengal region seemingly near the coastal regions from what I understand. I'm just wondering if an obvious answer exists that I'm just overlooking
