The reverse is also true - lot of words in Kerala which had sea-trade with Portugal and Spain, are close to their Portuguese/spanish equivalent, more than in other Indian languages. They are very closely related to the Iberian terms
- papaya
- sabola (Malayalam) versus Cebolla (Spanish/Portuguese)
- kashuandi (Cashew nut)
Other related terms like kappalandi (ship nuts - i.e. peanuts) indicate sea trade and that they were not endemic to India.
Looking at Malayalam terms gives a good indication as to which foods came to India via sea trade, possibly from South America, since the South was often the port of call. The only major exception I know is Mulaku (chillies) - even though chillies came from South America, the word does not indicate that.
Reminds me of the Shibboleth about Kappalandi vs Kadala in Malayalam, where the choice of vocabulary points to which region you come from (North vs South Kerala).
Even now, you can see the subjugation of Tamil History by the Indian government refusing to research the very important archeological find of Keezhadi.
Epigraphic research proves that much of the inscriptions from the Indus valley civilization is in Tamil. This threatens the Pro-Aryan groups for some unknown reason.
For example, we have no attested inscriptions of Tamil that predate 5th century BC. We do have Vedic inscriptions from 1400BC: https://en.m.wikipedia.org/wiki/Indo-Aryan_superstrate_in_Mi...

If you want to be a supremacist, you have to be supreme to something, and anything that might question that (even hypotheses) is a threat to that feeling.
Yes, Sometimes I am too naïve for my own good
However, from skimming the text, I would have to agree with the sibling commentator, that pointed to the reconstructed Proto-Dravidian language, rather than Tamil. The book you've shared suggests links of the IVC with Proto-Dravidian, not Tamil directly. Tamil as a distinct language is not attested before the 3rd Century BCE, making it a contemporary of the Prakrits in the North, around the time of Ashoka. The Sangam Literature period starts from the 1st Century BCE, roughly contemporaneous with the advent of Indo-Greeks in the North. Tamil =/= Proto-Dravidian, which would indeed have been around at the time of the IVC. Whether the IVC had contact with Proto-Dravidian or were Proto-Dravidian themselves is still an open question. Even the preliminary Ancient DNA evidence from the IVC does not settle this matter conclusively. (I'm a Geneticist, not a linguist)
