Meet this 5,00,000 years old predator: The real king of the Ice Age before the modern lions ruled

Time of India27-06-2025
Present-day Lions are called the king of the jungle with proud tan-yellow fur and a huge mane that rules over the animal kingdom, but could one ever imagine who used to rule over the animal kingdom during the ice age, when the world was covered under the ice thousands of years ago?
Long before kings wore crowns and lions roared across African savannas, another ruler walked the frozen plains of Ice Age Europe.
Lions, too, had a predecessor. A massive, silent, and powerful king known as the cave lion and it was a true monarch of the mammoth steppe.
These were larger than today's African lion variety, built to survive glacial winds and snow-covered landscapes, and this is not science fiction; some real proof of these ice age beasts has been found in the ancient caves of the icy landscapes of the Earth.
A relic- fossil is kept in this museum
During the ice age, the cave lion ruled over the mammoth steppes as the apex predator; genetic studies confirm it was a distinct species, different from today's African lion, and existed around 5,00,000 years ago.
And a beautifully preserved skull displayed at France's Muséum de Toulouse, a skull from Montmaurin's Grotte de Coupe-Gorge, part of a nearly complete skeleton found in clay bed 3S.
The Toulouse time capsule
Digitally scanned in 2015, the skull was transformed into a 3D reconstruction, letting visitors virtually see the extinct lion in interactive museum exhibits, according to reports by ima-solutions.
A Beast of Epic Proportions
Standing up to 1.2 m at the shoulder and measuring over 2 m in body length, cave lions were larger than most modern lions, though slightly smaller than the earlier Panthera fossilis.
Fossils show they had yellowish-grey coats, thick underfur for icy climates, and crucially, lacked manes, as confirmed by cave art in Lascaux and Chauvet.
These formidable felines hunted giant Ice Age herbivores such as reindeer, bison, and even young mammoths. They often clashed with other carnivores like cave hyenas, wolves, and cave bears, who were all vying for limited resources. Multiple cave paintings also suggest that these predators interacted with humans, dating back thousands of years. Neanderthals and later Upper Paleolithic humans hunted them for meat and pelts, as shown by prehistoric skinning marks and cave paintings
Carvings and paintings found in ancient caves
Ancient carvings and cave paintings of cave lions have been found in the famous Lascaux and Chauvet Caves in France, dating back roughly 15,000 to 17,000 years.
One particularly interesting drawing in the Chauvet cave shows two lions walking side by side. The larger one in the background appears to be male as it is drawn with a visible scrotum but no mane. This kind of detail has led researchers to believe that male cave lions likely didn't have manes at all, or if they did, they were very small, nothing like the thick manes we see on modern African lions.
Mystery of Disappearance
Cave lions vanished around 13,000 to 14,000 years ago. Theories suggest a combination of a warming climate, shrinking open habitats, diminishing prey, increasing competition with wolves, and human hunting pressure. Genetic studies even show a population bottleneck between 47,000–18,000 years ago. Their disappearance is also an indication of the collapse of the mammoth steppe ecosystem.

India's unique genetic legacy: implications for health and ancestry

The ability to extract and analyse genomic DNA from ancient human remains has revolutionised our understanding of human evolution. The genome is the full set of genetic instructions within an organism, containing all the information necessary for its development, function, and survival. It serves as a detailed blueprint or instruction manual, guiding the formation and operation of life—from the simplest organisms to the most complex. Genome is also the substrate for evolution, and variations in the genome reflect the evolutionary history of the organisms. The field of genomics studies genomes—how they function, evolve, and influence health and disease. One of the most transformative discoveries in this field is the evidence that modern humans interbred with now- extinct hominid species, such as Neanderthals and Denisovans. Genomic studies have revealed that after early modern humans migrated out of Africa, they encountered and mated with these archaic humans. As a result of this interbreeding, individuals of European and Asian descent today carry a small but measurable percentage of Neanderthal DNA—typically around 1–2%. Populations in Southeast Asia and Melanesia show even higher proportions of Denisovan DNA. Such findings refine the geographical and timeline narrative of the evolution of modern humans and the populating of the planet by people. These remnants of ancient genomes are not just evolutionary curiosities; they continue to influence our biology today. Comparative genomics of ancient and modern human DNA, in addition to providing profound insights into our evolutionary history, uncover biological adaptation and disease susceptibility. Some Neanderthal-derived genes are known to affect immune system function, making certain populations more resistant—or in some cases, more susceptible—to specific diseases including COVID-19. Meanwhile, Denisovan DNA has been linked to traits like high-altitude adaptation in Tibetan populations, enabling them to thrive in low-oxygen environments. Altogether, these discoveries have fundamentally changed our view of human origins. Rather than a linear or isolated evolution, they depict a dynamic and intertwined history marked by migration, interaction, and genetic exchange across different human species. This complex evolutionary tapestry underscores the shared and diverse heritage of humanity. Charting India's genetic landscape India, with over 1.4 billion people and nearly 5,000 distinct communities, is one of the world's most genetically diverse regions. Yet, it is underrepresented in major global genomic studies. While projects like the 1000 Genomes Project, UK Biobank, and others have included some Indian samples, most focused on expatriate populations and offered limited insight. As a result, major questions about the origins, migrations, and disease risks in Indian populations remain unresolved. To address this, researchers conducted one of most comprehensive genetic study of Indian populations to date, including people from diverse regions, language families, and underrepresented tribal groups (Lalji Singh and Thangaraj group, Nature Genetics, 2017). The study revealed that most genetic variation in Indians comes from a single major human migration out of Africa around 50,000 years ago. These early settlers later interbred with archaic human species such as Neanderthals (Europe and west Asia) and Denisovans (central, eastern, and southeastern Asia). This study highlighted the complex demographic history of India, revealing significant intermixing between two ancestral groups: the Ancestral North Indians (ANI) and Ancestral South Indians (ASI). This early admixture shaped the unique genetic landscape seen today, reflecting ancient migrations and population interactions over millennia. The research demonstrated that Indian populations are genetically distinct from other global groups, underlining the country's rich genetic diversity. Importantly, this work laid the foundation for understanding genetic predispositions to diseases prevalent in India, informing personalized medicine and public health strategies. By integrating geographical and temporal contexts, the study also contributed to reconstructing India's population history. Overall, Singh's work is a milestone in human genetics, emphasising the need to study indigenous populations to unlock health and evolutionary insights unique to India's genetic heritage. Another landmark genomics study published recently ((Moorjani and coworkers, Cell, June 2025) has revealed that most Indians have ancestry from three ancient groups: Ancient South Asian hunter-gatherers (AHG), Early Iranian farmers, and Steppe pastoralists. DNA from ancient Iranian populations, particularly from 3600–3500 BCE in present-day Tajikistan (Sarazm), shows that early farmers and herders contributed to the ancestry of various Indian populations, including Ancestral North and South Indians, Austroasiatic speakers, and East Asian-related groups. Archaeological findings also confirm trade and cultural connections with early South Asian civilizations like Mehrgarh and the Indus Valley. The study also explored the contribution of Neanderthal and Denisovan ancestry. Indians carry 1–2% of their DNA from these archaic humans and show the highest diversity in archaic DNA among all modern populations. Notably, some of these ancient variants affect immune function. For example, Neanderthal genes on chromosome 3 are associated with severe COVID-19 symptoms, while Denisovan variants are found in immune-related genes like those in the MHC and TRIM families. Additionally, researchers found 'ancestry deserts'—genomic regions that lack Neanderthal or Denisovan DNA. One such region includes the FOXP2 gene, linked to language development in humans. Taken together, these studies highlight India's deep and complex genetic history shaped by ancient migrations, endogamy, and archaic gene flow. Understanding this diversity is essential for developing accurate, inclusive, and effective medical and genomic research tailored to Indian populations. Endogamy and genetic diseases Over time, many Indian communities adopted endogamy—marrying within their group—leading to a high degree of genetic relatedness. The 2017 Nature Genetics study co-led by Kumarasamy Thangaraj analysed genome data from over 2,800 individuals across 275+ South Asian populations, revealing strong founder effects and endogamy (marriage within groups) in about one-third of these groups. This genetic isolation causes a high prevalence of population-specific rare recessive diseases unlike those seen elsewhere. For example, the Vysya community has a 100-fold higher rate of butyrylcholinesterase enzyme deficiency due to such founder events. The study demonstrated population-specific recessive disease gene mapping, such as identifying a mutation causing Progressive Pseudorheumatoid Dysplasia in southern Indian patients mostly from non-consanguineous marriages. The 2025 study led by multiple groups using genomes of about 2,700 individuals reported that on average, each person in the study had at least one fourth-degree relative, and levels of homozygosity (inheriting identical copies of genes) were significantly higher than in East Asian or European populations. While endogamy strengthened community ties, it also increased the risk of genetic disorders due to recessive disease-causing variants. Researchers identified more than 1,60,000 previously unreported genetic variants, many linked to congenital conditions, blood disorders, metabolism, drug responses, and diseases such as dementia. These variants are unique to Indian populations—rare across the country but often common in specific groups. These studies mark a shift in Indian genetic research from focusing on common diseases to exploring rare, population-specific disorders, paving the way for personalised medicine. They emphasise the importance of community-based genetic screening and counseling to ease the disease burden. By drawing on the distinct population history of South Asia's thousands of endogamous groups, this approach enables earlier diagnosis and more precise interventions. Also Read:Decoding the script: On the Genome India Project and its sequencing 10,000 Indian genomes India's genetic mosaic: a frontier for personalised medicine India is home to unparalleled human genetic diversity, comprising more than 5,000 distinct ethnic groups, each shaped by unique social, geographical, and cultural practices. Long-standing traditions of endogamy across these groups have resulted in the accumulation of numerous founder mutations, making the Indian population one of the richest repositories of naturally occurring genetic variants anywhere in the world. This diversity presents a transformative opportunity for India - not only to deepen scientific understanding of human gene function and biology but also to revolutionise the delivery of healthcare through precision and personalised medicine. The natural presence of variants across populations enables us to ask biological questions that cannot be replicated in model systems or generated through laboratory-induced mutations. With appropriate infrastructure and vision, India can position itself as a global leader in genome-driven science. Future perspectives India possesses a tremendous opportunity to leverage its population's genetic diversity. The successful sequencing of 10,000 Indian genomes (the Genome India project of Department of Biotechnology, Government of India) is a significant milestone, providing a valuable foundation for future research. This wealth of genomic data will be crucial for attracting stakeholders, including the pharmaceutical and biotechnology industries. Building on this success, the next phase should involve large-scale genome sequencing including millions of the Indian population in the context of various diseases and clinical features. We should also prioritise the creation of a national biobank modeled on the UK Biobank with longitudinal follow-up. This will be pivotal for advancing precision healthcare and driving a genomics industry revolution in the country. By pursuing this, India can not only improve the health of its population but also establish itself as a global leader in the field of genomics and genomics based medicine.

Fascinating facts about the heaviest snakes on earth

Source: Wikipedia Snakes are among the most mysterious and awe-inspiring creatures on the planet. While many people are familiar with venomous snakes or constrictors, few realize just how massive some species can get. The heaviest snakes on Earth are not only record-breakers in terms of size but also important players in their ecosystems. From the Amazonian anaconda to ancient giants like Titanoboa, these snakes push the boundaries of what's biologically possible. Their immense size, strength, and stealth make them some of the most formidable predators in the animal kingdom. Heaviest snakes on Earth: Top giants from Anaconda to Titanoboa 1. Green Anaconda (Eunectes murinus) – The Heaviest Living Snake Source: Wikipedia Average Length: 4 to 6 meters (13–20 feet) The green anaconda holds the title of the heaviest living snake on Earth, thanks to its incredibly muscular body and aquatic lifestyle. While pythons may grow slightly longer, no snake matches the green anaconda in sheer mass. These non-venomous constrictors feed on large prey such as capybaras, deer, and even caimans. They are most active at night and spend much of their lives submerged in swamps, rivers, and wetlands. Female green anacondas are significantly larger than males, sometimes by double the size. 2. Northern Green Anaconda (Eunectes akayima) – Newly Discovered Giant Length: Up to 7.5 meters (24.6 feet) In a major biological breakthrough, scientists discovered a new species of anaconda in Ecuador—called the Northern Green Anaconda (Eunectes akayima). by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Do you have a mouse? Desert Order Undo It is genetically distinct from the common green anaconda and weighs significantly more, with some specimens recorded at 500 kilograms. 3. Burmese Python (Python bivittatus) Average Length: 5 to 6 meters (16–20 feet) The Burmese python is one of the largest snakes in the world by length and weight. Native to Southeast Asia, it has become an invasive species in the United States, particularly in Florida. They can consume a wide range of prey, including birds, mammals, and even alligators. 4. Reticulated Python (Malayopython reticulatus) Max Recorded Length: 10.0 meters (32.8 feet) While not as heavy as the anaconda, the reticulated python is considered the longest snake in the world. It's slender compared to its South American counterparts but incredibly powerful and capable of taking down large mammals. Despite its massive size, the reticulated python is an excellent climber and swimmer. 5. African Rock Python (Python sebae) Length: Up to 6.5 meters (21 feet) Africa's largest snake, the African rock python, is known for its aggressive nature and powerful constriction. It preys on monkeys, antelope, and sometimes domestic animals. Though not venomous, it can be dangerous due to its size and strength. There have been rare reports of African rock pythons attacking humans, though these are extremely uncommon. 6. Titanoboa (Titanoboa cerrejonensis) – The Largest Snake in History Length: Approx. 13 meters (42 feet) The Titanoboa is an extinct snake species and the largest snake ever discovered. Fossils found in Colombia show that it lived in ancient tropical rainforests after the extinction of dinosaurs. Its massive size suggests it fed on giant crocodilian ancestors and other large reptiles. Titanoboa's body was so thick that it's believed to have been almost 1 meter (3.3 feet) wide.

Did UV Rays Doom Neanderthals?

Our ancestral cousins went mysteriously extinct around 40,000 years ago, while humans did not. The demise of one and survival of the other continues to flummox paleoanthropologists—but some researchers now think sunscreen and tailored clothing might have played a role. Around the time Neanderthals bit the dust, a weakening of the Earth's magnetic field resulted in exposure to higher doses of harmful ultraviolet radiation. Clothing would have offered some protection. Both groups wore animal skins, but evidence suggests Neanderthals tended to wear loosefitting cloaks, while Homo sapiens sewed form-fitting garments. Humans also coated themselves with mineral pigments, which would have functioned as an ancient SPF. It is unlikely that these differences in behavior alone would have resulted in the Neanderthals' demise, but researchers think that their exposure to increased radiation would have had detrimental effects. The increased exposure occurred when Earth's north and south magnetic poles began to wander from their traditional positions. The rotation of the planet and its molten core help generate a protective magnetic field that keeps our planet's ozone layer robust and protects us from high-energy particles that constantly flow from the sun. The field is anchored at the poles, where magnetic forces are most concentrated. But small changes in the core can cause the poles to wander. During the twilight of the Neanderthals, such a wandering caused the magnetic field to drop to about 10% of its average strength. Scientists call this the Laschamps event. To test the effects of the Laschamps, Agnit Mukhopadhyay, a University of Michigan space scientist, and his group created 3-D models of what Earth's magnetic field would have looked like during the event. The results, published in the journal Science Advances, showed where the magnetic field was compromised, allowing radiation and particles to slip through. Researchers know the magnetic field went haywire way back then by examining minerals smaller than the width of a human hair found within ancient deep-sea sediments and volcanic rocks. These tiny grains, which contain iron, become magnetized, and their alignment offers clues about the state of Earth's magnetic field at the time. The researchers' analysis suggests Earth's northern and southern latitudes up to 40 degrees would have been disproportionately affected by the weakening. This area in the Northern Hemisphere—including what is today Spain—is where many Neanderthal and Homo sapiens populations lived. 'As an anthropologist, I was intrigued, because I think a lot about how climate and weather might have affected Homo sapiens and other species, but I never thought about space,' said Raven Garvey, a professor of anthropology at the University of Michigan and Mukhopadhyay's co-author. For about a millennium or two, during the Laschamps event, Earth would have experienced higher levels of invisible, cosmic radiation. But the impact of a thinner ozone layer wasn't just about increased radiation exposure. It also would have affected cloud cover, wind belts, rainfall and general weather patterns. 'It's not that the UV kills everybody,' said Alan Cooper, an evolutionary biologist at Charles Sturt University in Australia who wasn't involved in the recent work but has published research with similar conclusions. 'It's climate change. Everything goes completely wild at that point.' Not only did Neanderthals disappear from the fossil record around this time, Cooper added, but so did other species across the disproportionately affected areas. Mukhopadhyay's group suggested two theories of what helped Homo sapiens, who interbred with Neanderthals, to survive: the use of a primitive kind of sunscreen known as ocher—a naturally occurring pigment composed of iron oxide often used for cave art—to protect their bodies from the sun, and clothing that hugged the body and covered more skin. Right around the time of the Laschamps event, there was an uptick in cave art at sites archaeologists have linked to Homo sapiens, according to Cooper. Anthropologists hypothesize that Homo sapiens also used ocher on their skin based on the fact that populations living in Africa and Australia today apply the pigment as a skin protectant, said Andrew Zipkin, an archaeological scientist affiliated with Arizona State University who wasn't involved in the recent study. Ocher is a naturally occurring pigment often used in cave paintings in what is now Spain. Archaeological sites linked to Neanderthals and modern humans have both yielded stone tools called scrapers used for processing animal hides to make them supple and wearable, Garvey said. But researchers have found evidence of a broader clothing-making tool kit at Homo sapiens-related sites. 'We're also seeing things like needles and awls and the kinds of implements that would be very useful to poke holes in these hides and then stitch them together with sinew in the mass production of tailored clothing,' she added. Anthropologists are careful to note that the coincident timing of the Neanderthal extinction and the Laschamps event could have been mere chance. Differences in population sizes and other things could also have made the species's survival less likely, according to Tony Capra, a University of California, San Francisco evolutionary geneticist who wasn't involved in the work. The goal of the recent work, according to the study authors, was to focus on one aspect of a multifaceted mystery. 'Whoever had the tailored clothing probably did have this advantage,' Garvey said. 'But was it exclusive to one group and was it enough to lead to the extinction of one and the proliferation of the other? These are million-dollar questions.'
