The tracing of genetic ancestry remains a challenging task due to the statistical similarity among populations across geographical regions. However, recent advances in genetic analysis, particularly the development of the Twigstats tool, are significantly enhancing our ability to reconstruct genetic histories at a very high resolution.

Key Insights from Genetic Research:

• Ancient DNA (aDNA): Prehistoric human ceremonial burials, mass grave mounds, and war graves are rich sources of ancient genetic material, offering key insights into population dynamics. These samples help us understand past migrations, cultural transitions, and the genetic legacy of ancient groups.
• Challenges in Ancestry Tracing:
  • Populations often share many genetic similarities, complicating the task of tracing ancestry across regions.
  • Ancient DNA samples are typically of lower quality compared to modern samples, limiting the precision of past genetic studies.
  • The movement of genes across time and space, through processes like gene flow, adds complexity to the understanding of population ancestry.

Traditional Genetic Techniques:

• Single Nucleotide Polymorphisms (SNPs): Used to identify natural genetic variations, SNP analysis has been central to reconstructing genetic histories. However, it is limited by its reliance on high-quality samples and struggles with closely related groups.
• Haplotypes and Genealogical Trees: By analyzing shared DNA segments (haplotypes) and rare variants, researchers gain a more comprehensive understanding of population structure and ancestry, which can reveal shifts in population over time.

The Emergence of Twigstats:

• What is Twigstats?
  • Twigstats is an advanced analytical tool that enhances the precision of ancestry analysis through time-stratified ancestry analysis, a method that allows for a more fine-grained look at genetic data.
  • It is designed to address the limitations of traditional methods by integrating SNPs, haplotypes, and rare genetic variants, providing a more holistic view of ancestry.
  • The tool is powered by statistical languages R and C++, which help researchers better manage and analyze complex genetic data.
• How It Works: Twigstats builds family trees by analyzing shared genetic mutations, identifying recent mutations that offer a clearer understanding of historical periods and events. It helps trace the evolution of populations and offers insights into their migrations, mixing, and cultural shifts.

Key Features and Impact of Twigstats:

• Time-Stratified Ancestry Analysis: Allows researchers to study how populations evolved over time, with a focus on specific historical periods.
• Enhanced Precision: Reduces statistical errors and enhances the precision of individual-level ancestry reconstruction.
• Higher-Resolution Mapping: Provides high-resolution genetic maps of migration patterns and admixture events across centuries.

Applications of Twigstats:

• Historical Case Studies: The tool has been used to study ancient genomes from Europe, particularly the Iron, Roman, and Viking Ages (500 BC to 1000 AD). It revealed the fine-scale genetic history of populations in regions like northern and central Europe, including the movement of Germanic and Scandinavian peoples.
  • Viking Age Insights: Researchers were able to trace the early presence of Scandinavian-like ancestry in regions such as Britain and the Baltic before the traditionally believed start of the Viking Age. This suggests earlier interactions and migrations from Scandinavia, which aligns with historical records of Anglo-Saxon and Viking movements.
  • Cultural Transitions: The analysis identified shifts in population genetics corresponding to cultural changes, such as the shift from the Corded Ware culture to the Bronze Age and the influence of the Wielbark culture.

Genetic Methods Used in the Study:

• Single Nucleotide Polymorphisms (SNPs): Commonly used to trace ancestry but requires high-quality samples.
• Haplotypes and Rare Variants: Offer more nuanced insights into population movements by considering combinations of genetic markers inherited together.
• Genealogical Tree Inference: Applied to both ancient and modern genomes, it provides detailed demographic and ancestry information, supporting the reconstruction of high-resolution genetic histories.

Case Study: India’s Genetic History (2009 Study)

• Researchers used SNP analysis to trace the genetic history of India, revealing two major ancestral groups:
  • Ancestral North Indians (ANI): Genetically closer to Central Asian, European, and Middle Eastern populations.
  • Ancestral South Indians (ASI): A distinct genetic group, showcasing India’s diverse population structure.

• GST compensation cess likely to continue beyond January 2026, with potential rebranding and new end-use defined.
• Revenue Collection: Estimated Rs 20,000 crore expected from the cess by February 2026, with recent receipts of Rs 12,068 crore in August 2024.
• Cess Nature: The compensation cess, originally intended for revenue shortfall, cannot merge with the 28% GST slab due to regulatory limitations.

Financial Context

• RBI Study Insights: Weighted average GST rate decreased from 14.4% at launch to 11.6%, now even below 11%, raising concerns among states.
• State Concerns: Many states, including Punjab and Kerala, seek a 2-5 year extension for the compensation period to stabilize finances.

Regulatory Framework

• Cess Legislation: GST Compensation Cess is governed by the Goods and Services Tax (Compensation to States) Act, 2017, initially set for five years.
• Taxpayer Obligations: All suppliers of designated goods/services must collect the cess, except exporters and those under the composition scheme.

Distribution Mechanism

• Calculation of Compensation: Based on projected revenue growth (14%) against actual revenue, with payments distributed bi-monthly.
• Surplus Distribution: Any surplus in the compensation fund post-transition period will be shared between the Centre and states.

Future Considerations

• Ministerial Panel: A panel established by the GST Council will recommend the cess's future and revenue sharing post-compensation.
• Tax Expert Opinions: Some experts argue against pursuing the revenue-neutral rate, suggesting broader tax base expansion instead.
• Revenue Gap Solutions: Options for addressing compensation fund deficits include revising cess formulas, increasing rates, or market borrowing.

Delhi High Court has upheld the constitutional validity of the anti-profiteering clause in the GST law, which mandates companies to pass on the benefit of lower taxes and input tax credits to consumers.

What is an ‘Anti-profiteering’ Activity?

• Any reduction in the rate of GST tax on any supply of goods or services or the benefit of input tax credit should have been passed on to the recipient by way of a commensurate reduction in prices.
• The wilful action of not changing the final price of the good or service by various means, despite the reduction in the rate of the tax for that particular good or service, amounts to “profiteering”.

How is the Anti-profiteering Mechanism Under the CGST Act?

• CGST mandate a 3-tier structure for investigation and adjudication of the complaints regarding profiteering.
  • a) National Anti-profiteering
  • b) Authority Directorate General of Safeguards
  • c) State-level screening committees and standing committee

How Does the Screening Committee and Standing Committee Work?

• GST council may constitute a standing committee, having members from both state and central government.
• Every state shall constitute one state-level screening committee.
  • It will have one member from the state government and one member from the central government as nominated by the respective appropriate authority.
  • The complaints or issues of local nature will be first examined by the screening committee.
• State-level screening and standing committee will examine the complaint and determine the prime facie evidence to support the validity of the complaint.
• If any committee satisfies that the supplier has contravened section 171 of the CGST Act, the case shall be transferred to DG Safeguards for further investigation.
• The committees shall complete the investigation within a period of a month from the date of the receipt of the application.

What is the Role of DG Safeguards in the Anti-profiteering Mechanism?

• DG safeguards are the main investigation arm in the anti-profiteering mechanism.
• It can summon the interested parties make inquiries or call the relevant documents.
• It can seek help from technical experts in the due course of investigation.
• DG Safeguards shall complete the investigation within a period of three months from the date of receipt of the report from either screening or standing committee.
• The period can be extended for another three months.

Who Can File the Complaint Against Profiteering?

• Any consumer or organisation experiencing a non-reduction in the price of the goods or service despite the reduction in the rate of GST can file a complaint with proper evidence.
• Any supplier, trader, wholesaler or retailer, who could not get the benefit of input tax credit on account of a reduction in the rate of GST, can also file the complaint with proper evidence.
