Do the right way

Danino has expressed dissatisfaction that many genetic studies have attributed the ‘spread of agriculture’ into the subcontinent to migrations. Just to be sure that no one thinks that the practice of agriculture is in the genes, I would like to point out that the spread of the technology of agriculture was associated with the movement of people; agriculturists who took the technology to new regions and taught it to the locals in the new region. Movement of people implies movement of genes. Some migrants ‘export’ their genes to a new region by taking spouses from the new region and producing children with them who stay in the new region. We can never be sure that the attribution of agriculture having been introduced to the Indian subcontinent by migrants is fully true. However, genetic data do support this model, especially of the spread of modern, organized agriculture.

Having said this, I must also emphasize, once again, that collection of more extensive data is always more helpful in understanding our past and of the spread of our inventions and innovations. A Y-chromosomal signature, haplogroup J, was shown to be associated with the spread of modern agriculture. This signature has its highest frequency in the Fertile Crescent region – the region comprising the present-day countries of Syria, Lebanon, Turkey – where the technology of modern agriculture was invented about 7,000–10,000 years ago. Collection of deeper data showed that this signature is quite heterogeneous and is composed of at least four sub-signatures, one of which – haplogroup J2b2 – is confined to the India–Pakistan region.

This sub-signature arose over 13,000 years ago and hence its introduction into India could not have been by migrants who introduced modern agriculture into India. We showed that the haplogroup J2b2 possibly arose in India, because the highest frequency of this haplogroup is found in India. We discovered multiple epicentres of this haplogroup in India and interestingly these epicentres neatly coincided with the seats of introduction of early forms of agriculture in India (as evidenced by the study of fossilized pollen grains by Fuller and his team). It is unlikely that haplogroup J arose independently multiple times in geographically separated places. It probably arose in an ancient population who had spread themselves in geographically separated regions and they invented rudimentary forms of agriculture independently in multiple geographical regions. However, it is notable that these early forms of agriculture remained largely confined to India and Pakistan region.

Question:
Danino believed that genetic studies, which “attributed the ‘spread of agriculture’ into the Indian subcontinent to migrations,” are:

1)incorrect because migrants did not introduce agriculture into the subcontinent.

2) true because it was indeed migrants who introduced agriculture into the subcontinent.

3) only partially correct as early forms of agriculture were indigenously developed in the subcontinent.

4) originally results of expert intuition but later validated by an improved ability to decipher evidence.

Correct Answer is 3 .
But I find AC 1 more suitable because 1st line of passage "Danino expressed dissatisfaction....."
