  • [pib] Hybodont Shark fossils found in Jaisalmer

    In a rare discovery, teeth of new species of Hybodont shark of Jurassic age have been reported for the first time from Jaisalmer by a team of officers from the Geological Survey of India (GSI).

    Hybodont Shark

    • Hybodonts, an extinct group of sharks, was a dominant group of fishes in both marine and fluvial environments during the Triassic and early Jurassic time.
    • However, hybodont sharks started to decline in marine environments from the Middle Jurassic onwards until they formed a relatively minor component of open-marine shark assemblages.
    • They finally became extinct at the end of the Cretaceous time 65 million years ago.

    Significance of the fossil

    • The newly discovered crushing teeth from Jaisalmer represents a new species named by the research team as Strophodusjaisalmerensis.
    • These sharks have been reported for the first time from the Jurassic rocks (approximately, between 160 and 168 million years old) of the Jaisalmer region of Rajasthan.
    • The genus Strophodus has been identified for the first time from the Indian subcontinent and is only the third such record from Asia, the other two being from Japan and Thailand.
    • It opens a new window for further research in the domain of vertebrate fossils.

    Back2Basics: Geological time-scale

  • Thawing Permafrost

    The latest IPCC report has warned that increasing global warming will result in reductions in Arctic permafrost and the thawing of the ground is expected to release greenhouse gases like methane and carbon dioxide.

    What is Permafrost?

    • ‘Permafrost’ or permanently frozen ground is land that has been frozen at or below 0 degrees Celsius for two or more consecutive years.
    • A staggering 17 per cent of Earth’s entire exposed land surface is comprised of permafrost.
    • Composed of rock, sediments, dead plant and animal matter, soil, and varying degrees of ice, permafrost is mainly found near the poles, covering parts of Greenland, Alaska, Northern Canada, Siberia and Scandinavia.
    • The Arctic region is a vast ocean, covered by thick ice on the surface (called sea ice), surrounded by land masses that are also covered with snow and ice.

    Permafrost thawing

    • When permafrost thaws, water from the melted ice makes its way to the caves along with ground sediments, and deposits on the rocks.
    • In other words, when permafrost thaws, the rocks grow and when permafrost is stable and frozen, they do not grow.

    Why thawing?

    • The link between the Siberian permafrost and Arctic sea ice can be explained by two factors:
    • One is heat transport from the open Arctic Ocean into Siberia, making the Siberian climate warmer.
    • The second is moisture transport from open seawater into Siberia, leading to thicker snow cover that insulates the ground from cold winter air, contributing to its warming.
    • This is drastically different from the situation just a couple of decades ago when the sea ice acted as a protective layer, maintaining cold temperatures in the region and shielding the permafrost from the moisture from the ocean.
    • If sea ice (in the summer) is gone, permafrost start thawing.

    Impact on Climate Change

    • Due to relentlessly rising temperatures in the region, since the late-twentieth century, the Arctic sea ice and surrounding land ice are melting at accelerating rates.
    • When permafrost thaws due to rising temperatures, the microbes in the soil decompose the dead organic matter (plants and animals) to produce methane (CH4) and carbon dioxide (CO2), both potent greenhouse gases.
    • CH4 is at least 80 times more powerful than CO2 on a decadal timescale and around 25 times more powerful on a century timescale.
    • The greenhouse gases produced from thawing permafrost will further increase temperatures which will, in turn, lead to more permafrost thawing, forming an unstoppable and irreversible self-reinforcing feedback loop.
    • Experts believe this process may have already begun. Giant craters and ponds of water (called ‘thermokarst lakes’) formed due to thawing have been recorded in the Arctic region. Some are so big that they can be seen from space.

    Why a matter of concern?

    • An estimated 1,700 billion tonnes — twice the amount currently present in the atmosphere — of carbon is locked in all of the world’s permafrost.
    • Even if half of that were to be released to the atmosphere, it would be game over for the climate.
    • Scientific estimates suggest that the Arctic Ocean could be largely sea ice-free in the summer months by as early as 2030, based on observational trends, or as late as 2050, based on climate model projections.

    Potential to cause another pandemic

    Ans. Permafrost has many secrets.

    • When the permafrost was formed thousands of years ago, there weren’t many humans who lived in that region which was necessarily very cold.
    • Researchers recently found mammoths in the permafrost in Russia.
    • And some of these mammoth carcasses when they begin to degrade again may reveal bacteria that were frozen thousands of years ago.
    • So there will be surprises. But whether they will be lethal surprises is just not possible to say.

  • Climate Action and Finance Mobilization Dialogue (CAFMD)

    India and the US has together launched the “Climate Action and Finance Mobilization Dialogue (CAFMD)”.

    What is CAFMD?

    • The CAFMD is one of the two tracks of the India-U.S. Climate and Clean Energy Agenda 2030 partnership launched at the Leaders’ Summit on Climate in April 2021, by PM Modi and US President Mr. Biden.
    • The dialogue will strengthen India-US bilateral cooperation on climate and environment.
    • It will also help to demonstrate how the world can align swift climate action with inclusive and resilient economic development, taking into account national circumstances and sustainable development priorities.

    Key agendas

    • The US will collaborate with India to work towards installing 450 GW of renewable energy by 2030.
    • Currently, India’s installed power capacity is projected to be 476 GW by 2021-22 and is expected to rise to at least 817 GW by 2030.

    CAFMD would have three pillars:

    1. Climate Action Pillar: which would have joint proposals looking at ways in emissions could be reduced in the next decade.
    2. Setting out a Roadmap: to achieving the 450GW in transportation, buildings and industry.
    3. Finance Pillar: would involve collaborating on attracting finance to deploy 450 GW of renewable energy and demonstrate at scale clean energy technologies.

    • He was influenced by the speeches of Dadabhai Naoroji, Bal Gangadhar Tilak, Maharaja of Baroda, and Bipin Chandra Pal, helping to make him a patriot who turned Swadeshi.

    Formation of provisional govt in exile

    • On 1 December 1915 during World War I Pratap established the first Provisional Government of India at Kabul in Afghanistan as a government-in-exile of Free Hindustan, with himself as President, Maulavi Barkatullah as Prime Minister, and Maulana Ubaidullah Sindhi as Home Minister, declaring jihad on the British.
    • Due to his revolutionary ideas Pratap had a good relationship with Lenin, who invited him to Russia after its liberation and welcomed him.
    • By this time, the British had noticed his activities, and the British Government of India put a bounty on his head, attached/confiscated his entire estate, and declared him a fugitive, causing him to flee to Japan in 1925.

  • 124 years of the Battle of Saragarhi

    This September 12 marks the 124th anniversary of the Battle of Saragarhi that has inspired a host of armies, books and films, both at home and abroad.

    What is the Battle of Saragarhi?

    • The Battle of Saragarhi is considered one of the finest last stands in the military history of the world.
    • Twenty-one soldiers were pitted against over 8,000 Afridi and Orakzai tribals but they managed to hold the fort for seven hours.
    • Though heavily outnumbered, the soldiers of 36th Sikhs (now 4 Sikhs), led by Havildar Ishar Singh, fought till their last breath, killing 200 tribals and injuring 600.

    What was Saragarhi, and why was it important?

    • Saragarhi was the communication tower between Fort Lockhart and Fort Gulistan.
    • The two forts in the rugged North-West Frontier Province (NWFP), now in Pakistan. were built by Maharaja Ranjit Singh but renamed by the British.
    • Though Saragarhi was usually manned by a platoon of 40 soldiers, on that fateful day, it was being held by only 21 soldiers from 36th Sikh (now 4 Sikh) and a non-combatant called Daad, a Pashtun who did odd jobs for the troops.
    • Saragarhi helped to link up the two important forts which housed a large number of British troops in the rugged terrain of NWFP.
    • Fort Lockhart was also home to families of British officers.

    What transpired on that day?

    • Around 9 am that day, the sentry at Saragarhi saw a thick haze of dust and soon realized that it was caused by a large army of tribals marching towards the fort.
    • The 8,000 and 15,000 tribals wanted to isolate the two forts by cutting off the lines of communication between them.
    • Unfortunately, the Pathans had cut the supply route between Fort Lockhart and Saragarhi.

    Who was Havildar Ishar Singh who led the troops?

    • Havildar Ishar Singh was born in a village near Jagraon.
    • He joined the Punjab Frontier Force in his late teens after which he spent most of his time on various battlefields.
    • Soon after it was raised in 1887, Ishar was drafted into the 36th Sikhs.
    • He was in his early 40s when he was given independent command of the Saragarhi post.
    • Ishar Singh was quite a maverick who dared to disobey his superiors but he was loved by his men for whom he was always ready to go out on a limb.

    How was the news of the battle received in Britain?

    • Making a departure from the tradition of not giving gallantry medals posthumously, Queen Victoria awarded the 21 dead soldiers — leaving out the non-combatant/
    • They were awarded the Indian Order of Merit (comparable with the Victoria Cross) along with two ‘marabas’ (50 acres) and Rs 500 each.

    How are the slain soldiers remembered?

    • In 2017, the Punjab government decided to observe Saragarhi Day on September 12 as a holiday.
    • Even today the Khyber Scouts regiment of the Pakistani army mounts a guard and salutes the Saragarhi memorial close to Fort Lockhart.

  • Thamirabarani Civilization is 3200 years old

     

    A carbon dating analysis of rice with soil, found in a burial urn at Sivakalai in Thoothukudi district of Tamil Nadu has yielded the date of 1155 BC, indicating that the Thamirabarani civilization dates back to 3,200 years.

    About Thamirabarani River

    • The Thamirabarani or Tamraparni or Porunai is a perennial river that originates from the Agastyarkoodam peak of the Pothigai hills of the Western Ghats.
    • It flows through the Tirunelveli and Thoothukudi districts of the Tamil Nadu state of southern India into the Gulf of Mannar.
    • It was called the Tamraparni River in the pre-classical period, a name it lent to the island of Sri Lanka.
    • The old Tamil name of the river is Porunai.

    Its history

    • Its many name derivations of Tan Porunai include Tampraparani, Tamirabarni, Tamiravaruni.
    • Tan Porunai nathi finds mention by classical Tamil poets in ancient Sangam Tamil literature Purananuru.
    • Recognised as a holy river in Sanskrit literature Puranas, Mahabharata and Ramayana, the river was famed in the Early Pandyan Kingdom for its pearl and conch fisheries and trade.
    • The movement of people, including the faithful, trade merchants and toddy tapers from Tamraparni river to northwestern Sri Lanka led to the shared appellation of the name for the closely connected region.
    • One important historical document on the river is the treatise Tamraparni Mahatmyam.
    • It has many ancient temples along its banks. A hamlet known as Appankoil is located on the northern side of the river.

    Significance of the carbon dating

    • This has provided evidence that there was a city civilisation in south India as long back as 3,200 years ago, the later part of the Indus Valley Civilisation.
    • Vicinity to the ancient port of Muziris, now known as Pattanam, in Kerala add another significance to the trade history of this site.
    • Now, research would be conducted at Quseir al-Qadim and Pernica Anekke in Egypt, which were once part of the Roman empire, as well as in Khor Rori in Oman, to establish the Tamils’ trade relations with these countries.
    • Potsherds bearing Tamil scripts have been found in these countries.
    • Studies would also be conducted in Southeast Asian countries, such as Indonesia, Thailand, Malaysia and Vietnam, where King Rajendra Chola had established supremacy.

  • NDA to admit Women: Centre

    The Centre gave the Supreme Court the “good news” that it had taken a decision to allow women entry into the National Defence Academy (NDA), so far a male bastion for recruitment into the Armed Forces.

    About National Defence Academy

    • The NDA is the joint defence service training institute of the Indian Armed Forces, where cadets of the three services train together before they go on to respective service academy for further pre-commission training.
    • It is located in Khadakwasla, Pune, Maharashtra.
    • It is the first tri-service academy in the world.
    • Applicants to the NDA are selected via a written exam conducted by the UPSC every year, followed by extensive interviews by the Services Selection Board.

    What was the latest development?

    • Recently, the Supreme Court upheld the right of serving Short Service Commission (SSC) women officers of the Navy to be granted Permanent Commission (PC) on a par with their male counterparts.

    Women in Armed Forces: Significance

    • The court ruled that women naval officers cannot be denied the right to equal opportunity and dignity entitled to under the Constitution on specious grounds such as physiology, motherhood and physical attributes.
    • The battle for gender equality is about confronting the battles of the mind.
    • History is replete with examples where women have been denied their just entitlements under law and the right to fair and equal treatment in the workplace.

    Why males have ever dominated the armed forces?

    • Militaries across the world help entrench hegemonic masculine notions of aggressiveness, strength and heterosexual prowess in and outside their barracks.
    • The military training focuses on creating new bonds of brotherhood and camaraderie between them based on militarized masculinity.
    • This temperament is considered in order to enable conscripts to survive the tough conditions of military life and to be able to kill without guilt.
    • To create these new bonds, militaries construct a racial, sexual, gendered “other”, attributes of whom the soldier must routinely and emphatically reject.

    Dimensions of the Issue

    Gender is not a hindrance: As long as an applicant is qualified for a position, one’s gender is arbitrary. It is easy to recruit and deploy women who are in better shape than many men sent into combat.

    Combat Readiness: Allowing a mixed-gender force keeps the military strong. The armed forces are severely troubled by falling retention and recruitment rates. This can be addressed by allowing women in the combat role.

    Effectiveness: The blanket restriction for women limits the ability of commanders in theatre to pick the most capable person for the job.

    Tradition: Training will be required to facilitate the integration of women into combat units. Cultures change over time and the masculine subculture can evolve too.

    Cultural Differences & Demographics: Women are more effective in some circumstances than men. Allowing women to serve doubles the talent pool for delicate and sensitive jobs that require interpersonal skills, not every soldier has.

    Hurdles for Women

    Capabilities of women: Although women are equally capable, if not more capable than men, there might be situations that could affect the capabilities of women such as absence during pregnancy and catering to the responsibilities of motherhood, etc.

    Adjusting with the masculine setup: To then simply add women to this existing patriarchal setup, without challenging the notions of masculinity, can hardly be seen as “gender advancement”.

    Fear of sexual harassment: Sexual harassment faced by women military officers is a global phenomenon that remains largely unaddressed, and women often face retaliation when they do complain.

    Gender progressiveness could be an illusion: Women’s inclusion is criticized as just another manoeuvre to camouflage women’s subjugation and service as women’s liberation.

    Battle of ‘Acceptance’: Acceptance of women in the military has not been smooth in any country. Every army has to mould the attitude of its society at large and male soldiers in particular to enhance acceptability of women in the military.

    Job Satisfaction: Most women feel that their competence is not given due recognition. Seniors tend to be over-indulgent without valuing their views. They are generally marginalised and not involved in any major decision-making.

    Doubts about Role Definition: The profession of arms is all about violence and brutality. To kill another human is not moral but soldiers are trained to kill.

    Physical and Physiological Issues: The natural physical differences in stature, strength, and body composition between the sexes make women more vulnerable to certain types of injuries and medical problems. The natural processes of menstruation and pregnancy make women particularly vulnerable in combat situations.

    Comfort Level: Most women accepted the fact that their presence amongst males tends to make the environment ‘formal and stiff’. The mutual comfort level between men and women colleagues is often very low.

    Conclusion

    • Concern for equality of sexes or political expediency should not influence defence policies.
    • Armed forces have been constituted with the sole purpose of ensuring defence of the country and all policy decisions should be guided by this overriding factor.
    • All matters concerning defence of the country have to be considered in a dispassionate manner.
    • No decision should be taken which even remotely affects the cohesiveness and efficiency of the military.

    Way ahead

    • Induction of women into armed forces should be on the basis of their abilities and not on the basis of their gender.
    • The training for both women and men should be standardized to eliminate differentiation based on physical capabilities.
    • The career aspects and opportunities for women need to be viewed holistically keeping the final aim in focus.

  • Places in news: Qeqertaq Avannarleq Island

    A group of researchers who went out to collect samples off the coast of Greenland in July found themselves on a tiny, uninhabited and previously unknown island.

    Qeqertaq Avannarleq

    • Measuring 60×30 metres and with a peak of three metres above sea level, it has now become the new northernmost piece of land on Earth.
    • Before this, Oodaaq was marked as the Earth’s northernmost terrain.
    • The new island is made up of seabed mud and moraine, i.e. soil, rock and other material left behind by moving glaciers, and has no vegetation.
    • The group has suggested the discovery be named ‘Qeqertaq Avannarleq’, which is Greenlandic for “the northernmost island”.

    How this island came to existence?

    Ans. Undoubtedly, climate change in Greenland

    • Global warming has had a severe effect on the ice sheet of Greenland.
    • The new island, which was exposed by shifting pack ice, is, however, not a direct consequence of climate change.

  • Visva-Bharati University

    The Calcutta High Court has directed that there can be no protest by the students within 50 meters of academic buildings at Visva-Bharati University.

    Visva-Bharati

    • Visva-Bharati is a central research university and an Institution of National Importance located in Shantiniketan, West Bengal, India.
    • It was founded by Rabindranath Tagore who called it Visva-Bharati, which means the communion of the world with India.
    • Until independence, it was a college.
    • Soon after independence, the institution was given the status of a central university in 1951 by an act of the Parliament.

    Its history

    • The origins of the institution date back to 1863 when Debendranath Tagore was given a tract of land by the zamindar of Raipur, zamindar of Kirnahar.
    • He set up an ashram at the spot that has now come to be called chatim tala at the heart of the town.
    • The ashram was initially called Brahmacharya Ashram, which was later renamed Brahmacharya Vidyalaya.
    • It was established with a view to encouraging people from all walks of life to come to the spot and meditate.
    • In 1901 his youngest son Rabindranath Tagore established a co-educational school inside the premises of the ashram.
    • From 1901 onwards, Tagore used the ashram to organize the Hindu Mela, which soon became a center of nationalist activity.
