Which specific Tamil-Brahmi cave inscription site located in the Wayanad district of Kerala provides crucial epigraphical evidence of prehistoric human habitation and petroglyphs dating back to the Neolithic period?

💡 Solution & Explanation

The Edakkal caves situated in the Ambukuthi hills of Wayanad feature rare pictorial rock carvings and early Tamil-Brahmi scripts, offering vital clues about the literacy and migration patterns in ancient Kerala. Marayoor is renowned for its dolmens and megalithic burial sites rather than cave petroglyphs with Brahmi writing. Edakkal epigraphs contain personal names and titles associated with early South Indian mercantile groups.
