Scientists carry out first ever Genetic Study on Lakshadweep Island’s Natives

For the very first time scientists carried out genetic study on people of Lakshadweep Islands. It was conducted by a team of researchers at CSIR’s (Council of Scientific & Industrial Research) Centre for Cellular and Molecular Biology (CCMB). The authors studied major islands of Kadmat, Andorth, Chetlat, Agatti, Kalpeni, Bitra, Kiltan and Minicoy of Lakshadweep.

Key Findings of Study

  • They studied major islands of Kadmat, Andorth, Chetlat, Agatti, Kalpeni, Bitra, Kiltan and Minicoy of Lakshadweep.
  • They analyzed DNA samples of 557 individuals from eight major islands for mitochondrial DNA and 166 individuals for Y chromosome markers.
  • Unlike earlier when it was presumed that people of Lakshadweep Islands might have presence of genetic signatures of ancient people, like Andamanese and Australian aboriginals. It shows that majority of human ancestry in Island of Lakshadweep is largely derived from South Asia with minor influences from East and West Eurasia.
  • It found close genetic link of Lakshadweep islanders with people from Maldives, Sri Lanka and India. However, it did not found any evidence of early human migration through Lakshadweep islands.
  • Although, genetic composition of first human settlement of Lakshadweep archipelago is still not clear. But it found that there is a strong founder effect for both paternal and maternal lineages which signals that island’s population had limited genetic mixing.

Geographical Facts: Lakshadweep

  • It was formerly (1956–73) called Laccadive, Minicoy, and Amindivi Islands. It is India’s union territory.
  • It is an archipelago (extensive group of islands) of 36 islands in Laccadive Sea, scattered over 30,000 square miles of Arabian Sea.
  • Its administrative centre (capital) is Kavaratti.
  • ‘Lakshadweep’ in Malayalam language and in Sanskrit means “Hundred Thousand Islands”.
  • Nine Degree Channel: separates Minicoy Island from rest of Lakshadweep.
  • Eight Degree Channel: Separates entire group of Lakshadweep islands from Maldives.

BRO Celebrates 59th Raising Day on May 7

The Border Roads Organisation (BRO) was formed on on 7 May 1960, with primary goal of securing India’s borders and developing infrastructure in remote areas of India’s north and north eastern states. On 7 May 2019 BRO celebrated its 59th Raising Day (foundation day).

About BRO

  • It is a leading road construction agency under Ministry of Defence.
  • Its primary role is to provide road connectivity in India’s border areas. It also creates up-grades and maintains infrastructure along borders to meet India’s overall tactical and strategic goals.
  • Apart from road construction it also executes maintenance works along Northern and Western frontiers mainly to meet strategic requirements of Indian Army. It is responsible for over 53,000 Km roads.
  • Its work involves Formation Cutting, Surfacing, Bridge construction and Resurfacing.
  • It contributes towards India’s strategic objectives in neighbouring regions by constructing roads in friendly foreign nations like Afghanistan, Bhutan, Myanmar, Sri Lanka and Nepal.
  • Disaster management: It has played important role in reconstruction work after tsunami in Tamil Nadu in 2004, Kashmir earthquake in 2005, Ladakh flash floods in 2010 etc.

Recent Developments

  • To meet challenges of enhancing overall strategic connectivity along borders BRO has begun organizational re-structuring and simplified procedures with adequate delegation of financial powers to executives.
  • To enhance its capabilities it is now executing works in combination of departmental, contractual and EPC (Engineering, Procurement and Construction) mode.
