Archaeological explorations in the Teesta and Rangit river valleys of Sikkim have primarily yielded artifacts belonging to which prehistoric technological horizon?

💡 Solution & Explanation

Archaeological investigations in Sikkim have uncovered polished stone axes, celts, and tools characteristic of the Neolithic era, indicating early human adaptation to the rugged forested terrain of the eastern Himalayas. Paleolithic and Chalcolithic markers are sparse or absent in this specific mountainous zone. These Neolithic implements demonstrate that early forest-dwelling communities engaged in rudimentary shifting cultivation and stone-working.
