I want to know the answer to the following question:
What economic activity in the Horn of Africa did the ancient Somalis connect to the rest of the world?
All the background I'm provided with is that "Somali sailors and merchants were the main suppliers of frankincense, myrrh and spices, items which were considered valuable luxuries by the Ancient Egyptians, Phoenicians, Mycenaeans and Babylonians.". Is that enough to answer the question?
