The Surya Narayan article suggests that there is a lack of evidence of milk usage among the Harappan people. Speculations arise that the absence of evidence could be due to the Harappans’ potential inability to digest milk. Contradictory claims regarding a gene from Europe introducing milk consumption to India are debunked by ancient DNA studies.

Akshita Surya Narayan’s study on Harappan pottery indicates a diet rich in odd chain fatty acids, typical of ruminant fats like butter. Pottery showed no signs of charring or shooting marks, suggesting they were not used for cooking meat. Absence of cut marks on buffalo and cattle bones challenges the assumption of beef consumption. The article disputes claims that sheep and goat meat were not significant in the Harappan diet. Chicken, a part of the Harappan civilization, was even exported to Mesopotamia. The Genographic Project, an influential initiative studying human migration, supports the theory of human origin in Africa. Contrary to the Aryan invasion hypothesis, ancient DNA studies suggest that Indian cattle genes migrated to regions like Anatolia, Balkans, and Central Asia. The project challenges Eurocentric perspectives in archaeology and anthropology by emphasizing the global migration of humans.

While the Genographic Project is reputable, it has faced criticism for potential data manipulation and biased conclusions. The project primarily focuses on ancient human genomes, particularly from India, but the availability of data can be limited.
