Connection Between Dinosaurs and Birds
For Prelims: Connection Between Dinosaurs and Birds, Cranial Evolution, Endothermic Animals, Theropod Lineage.
For Mains: Connection Between Dinosaurs and Birds.
Why in News?
Recently, a study published in the journal Royal Society Open Science, suggests a connection between Birds and Dinosaurs.
What is the Methodology of Research?
- The Researchers employed cutting-edge techniques, including Computed Tomography (CT) scans and 3D reconstruction, to analyze the nasal cavities of 51 present-day species.
- These species encompassed birds, mammals, reptiles (including crocodiles and turtles), and lizards. Additionally, the researchers digitally reconstructed the nasal cavity of a velociraptor, a type of theropod dinosaur, based on fossils.
- They focussed primarily on the nasal cavity to enhance understanding of the cranial evolution (changes in organism's skull over time) from dinosaurs to birds.
- They explored the possibility that the nasal cavity played a crucial role in brain cooling and regulation.
What are the Key Findings of the Study?
- Nasal Cavity Size and Warm-Bloodedness:
- Endothermic (Warm-blooded) animals, including birds and mammals, had larger nasal cavities relative to their head sizes compared to cold-blooded animals.
- This size difference indicated a potential link between warm-bloodedness and nasal cavity dimensions.
- Respiratory Turbinates and Brain Cooling:
- Warm-blooded animals exhibited a complex structure known as the respiratory turbinate within their nasal cavities. One of the primary functions of this structure was brain cooling.
- This discovery challenged the previously held belief that larger nasal cavities primarily facilitated whole-body metabolism.
- Warm-blooded animals exhibited a complex structure known as the respiratory turbinate within their nasal cavities. One of the primary functions of this structure was brain cooling.
- Evolutionary Implications for Dinosaurs and Birds:
- The cooling mechanism might have provided an advantage for warm-blooded creatures, including birds and mammals, influencing their evolution.
- In contrast, the reconstructed nasal cavity of the velociraptor indicated a lack of a developed cooling system, suggesting differences in thermoregulation between theropod dinosaurs and modern birds.
- Influence of Maxilla on Nasal Passage:
- The shape of the nasal passage in the velociraptor was influenced by the maxilla, the lower jaw bone.
- They proposed that a reduction in the maxilla in the theropod lineage led to the nasal cavity becoming a crucial apparatus for their thermal regulation strategy.
What is the Significance of the Study?
- While the study provided novel insights into the potential function of respiratory turbinates in brain cooling, the researchers emphasized the need for more comprehensive research to validate their hypotheses.
- Understanding the complex interplay between anatomical adaptations and environmental factors remains a key focus for future studies.
What are Warm Blooded and Cold Blooded Animals?
Aspect | Warm-Blooded Animals (Endotherms) | Cold-Blooded Animals (Ectotherms) |
Metabolism | High metabolic rate | Low metabolic rate |
Body Temperature | Maintain a relatively constant body temperature independent of the environment | Body temperature varies with the external environment |
Energy Source | Rely on internal heat production (metabolism) to maintain body temperature | Depend on external sources of heat for thermoregulation |
Activity Levels | Can be active in a wide range of environmental conditions | Activity levels influenced by temperature; often more active in warmer conditions |
Adaptability to Environments | Can inhabit diverse environments due to their ability to regulate body temperature | Limited in their habitat choices by temperature preferences |
Reproductive Rate | Generally have lower reproductive rates due to high energy demands | May have higher reproductive rates due to lower energy demands |
Examples | Mammals (including humans), birds | Reptiles (such as snakes, lizards), amphibians, most fish, invertebrates (except some insects) |
What is the Theory of Evolution by Charles Darwin?
- About:
- Charles Darwin's theory of evolution is a foundational concept in biology that explains how species change over time and how new species arise.
- Darwin's ideas revolutionized the understanding of life on Earth and provided a comprehensive explanation for the diversity of species.
- Key Elements:
- Descent with Modification: Darwin proposed that all species share common ancestors and that species change gradually over time through a process called descent with modification, meaning that new species arise from existing ones.
- Natural Selection: The central mechanism of Darwin's theory is natural selection. He observed that in every generation, more offspring are produced than can survive due to limited resources, leading to a struggle for survival.
- Variation: Within any population, there is variation in traits among individuals. Some of these variations are heritable, meaning they can be passed down to offspring.
- Adaptation: As natural selection acts on the variations in a population, individuals with traits that are better suited to their environment become more successful at surviving and reproducing.
- Speciation: Over long periods of time and through the accumulation of gradual changes, populations can become so different from each other that they can no longer interbreed. This leads to the formation of new species.
What is Computed Tomography (CT)?
- It is a medical imaging technique that uses X-rays and advanced computer processing to create detailed cross-sectional images of the body.
- Like an X-ray, it shows structures inside the body. But instead of creating a flat, 2D image, a CT scan takes dozens to hundreds of images of the body.
- Healthcare providers use CT scans to see things that regular X-rays can’t show.
- For example, body structures overlap on regular X-rays and many things aren’t visible.
- A CT shows the details of each of the organs for a clearer and more precise view.
Nuclear Rocket for Space Travel
For Prelims: NASA, Demonstration Rocket for Agile Cislunar Operations, Project Orion, Atomic bomb, Perseverance Rover - NASA, India’s Mars Orbiter Mission, UAE’s Hope Mars Mission
For Mains: Significance of DRACO, Nuclear Propulsion System
Why in News?
NASA in collaboration with the United States Defense Advanced Research Projects Agency (DARPA) is seeking a nuclear propulsion system that could potentially cut down the travel time to Mars by half.
- This ambitious initiative, known as the Demonstration Rocket for Agile Cislunar Operations (DRACO) and the launch is scheduled for late 2025 or early 2026.
What is DRACO?
- About: The DRACO project is offering the prospect of shorter travel times between celestial bodies and improved fuel efficiency. Central to DRACO's vision is a nuclear reactor that utilizes the energy derived from the fission of uranium atoms.
- Significance: DRACO hold the potential to revolutionize space travel in numerous ways:
- Acceleration and Speed: Unlike traditional rocket engines that rely on chemical reactions (fuel like hydrogen or methane with oxygen), nuclear reactions generate far more energy, enabling the spacecraft to accelerate continuously throughout its journey.
- This acceleration could significantly shorten travel times to distant destinations like Mars.
- Enhanced Fuel Efficiency: Nuclear propulsion systems yield greater fuel efficiency, reducing the need to carry excessive propellant.
- This advantage can drastically lower the duration of interplanetary voyages.
- Minimized Exposure: Expedited travel times translate to reduced exposure of astronauts to the harsh conditions of deep space.
- The potential risks associated with extended space travel, such as radiation exposure and isolation, could be mitigated through quicker journeys.
- Military Applications: Beyond its application in space exploration, DARPA's involvement hints at the potential for nuclear propulsion to facilitate rapid maneuvers of military satellites in Earth's orbit.
- Acceleration and Speed: Unlike traditional rocket engines that rely on chemical reactions (fuel like hydrogen or methane with oxygen), nuclear reactions generate far more energy, enabling the spacecraft to accelerate continuously throughout its journey.
- Concern:
- Safety Concerns: One of the primary concerns with using nuclear fuel in space is the potential for accidents or malfunctions that could release radioactive material into space or back to Earth.
- Such incidents could have severe environmental and health consequences.
- Launch Risks: Launching spacecraft with nuclear fuel on board presents risks, as there is always a chance of a launch failure or explosion, leading to the dispersion of radioactive material over a wide area.
- Safety Concerns: One of the primary concerns with using nuclear fuel in space is the potential for accidents or malfunctions that could release radioactive material into space or back to Earth.
What is the Historical Context of Nuclear Propulsion and How DRACO is Different?
- Projects like Orion, Rover, and NERVA explored nuclear-powered propulsion systems, although these initiatives were not fully realized.
- Notably, Project Orion considered using atomic bomb explosions for acceleration, while Project NERVA aimed to develop nuclear-thermal engines akin to the DRACO engine.
- DRACO marks a significant evolution from its predecessors due to several key differentiators:
- Fuel Enrichment: Unlike Project NERVA, which used weapons-grade uranium, DRACO employs a less-enriched form of uranium.
- This shift enhances safety and minimizes the risks associated with the use of radioactive materials.
- In-Space Activation: The nuclear reactor within the DRACO engine remains dormant until it reaches space.
- This precautionary measure mitigates the potential for radioactive accidents during launch or on Earth.
- Fuel Enrichment: Unlike Project NERVA, which used weapons-grade uranium, DRACO employs a less-enriched form of uranium.
Note:
- Atomic Bomb Explosions: Atomic bomb explosions involve the rapid and uncontrolled release of nuclear energy through a chain reaction of nuclear fission.
- The core of the bomb contains fissile material, like uranium-235 or plutonium-239.
- Nuclear-Thermal Engines: Nuclear-thermal engines are propulsion systems that use a nuclear reactor to heat a propellant, usually hydrogen, to high temperatures.
- The heated propellant is then expelled through a nozzle at high velocity, creating thrust according to Newton's third law of motion.
Mars
- About: Mars is the fourth planet from the Sun in our solar system. It is often referred to as the "Red Planet" due to its reddish appearance caused by iron oxide (rust) on its surface.
- Atmosphere: Mars has a thin atmosphere primarily composed of carbon dioxide (95.3%), with traces of nitrogen and argon.
- Major Surface Features:
- Olympus Mons: The largest known volcano in the solar system.
- Valles Marineris: A massive canyon system.
- Polar Ice Caps: Ice caps made of water and frozen carbon dioxide (dry ice) at the poles.
- Dusty Surface: The surface is covered in fine dust and rocks.
- Liquid Water: Liquid water is rare, but evidence suggests past liquid flows.

- Amazon Cooperation Treaty Organization (ACTO) is an international organization “aimed at the promotion of sustainable development of the Amazon Basin”.
- Colombia at the Amazon summit proposed that 80% of the Amazon should be protected from deforestation and degradation by 2025 but did not find support from all the members.
- Scientists have warned for long that if the combined deforestation and degradation of the Amazon crosses a 20-25% threshold, the forest could reach an irreversible tipping point that may result in the dieback of the entire ecosystem.
- The Belem Declaration released during the Amazon Summit recognises Indigenous knowledge as a condition for biodiversity conservation and calls for ensuring full and effective participation of Indigenous Peoples in decision-making and public policy formulation processes.

Jeevan Pramaan
- The Department of Pension & Pensioners’ Welfare (DoPPW) has taken proactive steps to enhance the ease of living for Central Government pensioners through the widespread promotion of Digital Life Certificates (DLC), known as Jeevan Pramaan.
- Pensioners must submit DLC every November (with a provision for those aged 80 years and above in October) to ensure continuous pension disbursement.
- Initially, the submission of DLCs involved biometric methods. Subsequently, in collaboration with MeitY, the department introduced a pioneering Face Authentication technology system linked to the Aadhar database.
- This innovation enables pensioners to generate their Life Certificates via any Android-based smartphone. This reduces reliance on external biometric devices, rendering the process more accessible and affordable, especially for the broader population.
- To ensure the success of the campaign, detailed guidelines have been issued These guidelines include :
- Nodal officers nominated for the campaign.
- Awareness through banners, posters, and ATMs.
- Utilization of technology during doorstep banking and branch visits.
- Camps for easy submission, and home visits for bedridden pensioners.
