Have we not evidence that the ancient Cholas discovered South America long before Columbus and that the Inca Sun Worshipers of Peru are none but the descendants of "our Chola ancestors" (vide Neelakanta Sastri "History of S. India" and M. Monohan's "Chola's in America 1976", p. 11-20). The Incas had their Temple of the Sun God (Peru) much like the one in Konark in Orissa built by the Cholas. The Chola chieftains (Incas) of America styled themselves as "Raghuvamsa Manickam". This shows that they belonged to the Raghuvamsa of Sri Rama whose ancestor Sibi Chakravarti is well described in ancient Tamil literature as the Chola king Sembian. This takes us to a very relevant inference that the ancestors of Dasaratha are as much the ancestors of the Tamils. One other ancestor of Sri Rama, Musu Kunthan, is none other than the Musu Kuntha Chola in ancient Tamil history. This Musu Kunthan's reign was during the second Tamil Sangam age 4800-2800 BC.
