Humans and the fear of snakes exist in the genetics Few people know that, ophidiophobia or the horrible obsession with snakes and round, long, legless animals in general is the most common fear in human society (1/3 of humanity is afraid of snakes). In addition, scientists have confirmed: Most primates have inherited the instinct to… be afraid and run away from snakes. The reason, prehistoric people were so afraid of snakes because they had to face giant carnivorous reptiles, not hostages like now. First is Titanoboa cerrejonensis : Nearly 13m long, weighing about 1 ton, is considered the largest snake species discovered by man However, some studies indicate that Titanoboa was a piscivore rather than a megafauna-killer. So, is it a giant but gentle animal? Titanoboa cerrejonensis. Before humans left records of Titanoboa, the title of giant snake was given Gigantophis garstini They appeared about 20 million years after Titanoboa in Africa with a length of about 11m. Gigantophis’ favorite food was the ancestor of the modern world’s elephants. Gigantophis garstini. Madtsoia madagascariensis: Giant snake that specializes in eating dinosaurs Gigantophis’ close relative is Madtsoia madagascariensis , another giant snake that lived in Madagascar for several million years during the age of the dinosaurs. They lived with iconic dinosaurs like Majungasaurus , Masiakasaurus and Rahonavis as well as giant frogs Beelzebufo . And perhaps, Madtsoia is also more than enough to eat all the dinosaurs mentioned above. Madtsoia madagascariensis. Both Madtsoia and Gigantophis belong to the ancient family of giant snakes known as the Madtsoiids. Both of these genera lived long ago, but some survived until recently in Australia. Until Wonambi naracoortensis , a snake more than 6m long has inspired the legend of the Rainbow Snake of primitive Australians This size seems modest compared to the previous monsters, but it is still significantly larger when compared to the Anaconda python. Furthermore, over time it has coexisted with giant kangaroos, marsupial lions and primitive Australians – it may have inspired the Rainbow Serpent legend. mythical animals of Australia). Rainbow Snake, one of the mythical animals of Australia. Yurlunggur camfieldensis , a reptile that the Yurlungur aborigines believe is made of bronze, specializes in hunting virgins Living in the same period and place as Wonambi is a species Yurlunggur camfieldensis. They are named after the Yurlungur Aboriginal mythology – which tells of a bronze snake excited by the smell of a young girl’s menstrual blood that would come to eat her and her family. Yurlunggur is said to be up to 8m long and is a self-burrowing aquatic species. They will hunt underwater but live in burrows with soft ground. Though non-poisonous, the terrifying force of the contractions would kill their prey, similar to most pythons today. Yurlunggur camfieldensis. Palaeophiidae, Giant water snake up to 10m long, specializing in eating whales and prehistoric sharks Come to another ancient genus of giant snakes, Palaeophiidae of the genus Palaeophiid . Palaeophiidae evolved over 70 million years ago, and like the Madtsoiids, they survived the K-PG Great Extinction. Similar to modern sea snakes, Palaeophiidae lived entirely in water, only much larger. According to researcher Gary Meaney, Palaeophis colossaeus New is the scariest of all – it can hunt whales, giant sharks in the Eocene waters. It is very large, up to 10m long. Palaeophis colossaeus. Pterosphenus , a giant warm-blooded snake, much more active than a cold-blooded reptile Another branch of the Palaeophiid genus, Pterosphenus , which is also horrifying in size: 7m. In addition, these are giant sea snakes that have the ability to reproduce early and have a warm-blooded metabolism, making them more active than many other slow reptile monsters. Pterosphenus. To the giant, tens of meters long reptiles that dominate the earth During the Pliocene (geological period), did the Australian continent exist the giant python Bluff Downs or Liasis dubungila – one of the few prehistoric animals with a common name. It is more than 10m long and is considered the largest snake ever of this continent. Bluff Downs or Liasis dubungila. In prehistoric times, branches of the python family also gained horological dimensions. One of them is Chubutophis grandis, estimated at 22m in length. And if that’s true, Titanoboa will lose the title of the largest snake in history. They lived in the Miocene with a host of giant South American creatures: Elephant-sized Caimans, giant gharials, giant tigers and giant turtles… Chubutophis grandis. Finally, let’s come to the largest venomous snake known: Laophis , closely resembles the poisonous Gabon viper, which lived on the Greek islands during the Pliocene. According to scientists, it weighs twice as much as the largest venomous snakes of the modern world, more than 4m long. This size has nothing to do with the reptiles listed above, but they are not poisonous… Laophis. As such, Titanoboa was the only nightmare snake that slithered around in ancient times. It may be the biggest, but it’s probably not the scariest.

This species is extremely toxic, it prefers to hide in coral reefs, rocks and sandy seabeds from intertidal to intertidal zones in southeastern China and tropical seas. Their bodies contain more than 200 pharmacologically active substances and a single drop of venom can kill 20 adults. To date there have been at least 100 recorded deaths from the venom of this species and the actual number could be much higher. The creature we are talking about here is the Cone Snail, also known as the cone snail, is a marine gastropod mollusk, so far more than 70 species have been found along the coast. along the coast of China and there are more than 1,000 species discovered in the world. Their venom is made up of a mixture called peptide conus. Each of them will have a unique venom formula. More than 50,000 conus peptides have been discovered, they are all neurotoxins and no vertebrate species on our planet possesses this form of venom. The Cone Snail has a mostly cone-shaped appearance and the largest can be 23 cm long. They are purely carnivores and predators, feeding mainly on sea worms, small fish, mollusks and even other cone snails. It can release venom at any time in its life, and this species is always ready to wipe out all living things around it. But surely you will find it difficult to understand because in our impression, snails are very slow-moving mollusks, how can they hunt, especially fast-moving species like fish? In fact, the secret to their hunting is not in their movement speed, instead they hunt by using their venom and developing an extremely efficient venom system. All cone snails are masters of poisons, likened to the five poisons in the animal kingdom. They have a tongue pocket in their throat, which contains many hollow toothed tongues, which resemble spearheads and are made of hard chitin. Because of their slow movement speed, cone snails often hunt by “holding a tree and waiting for rabbits”, which will lie in the sand at the bottom of the water, only revealing their long tubular mouth and tentacles in the sand. Once it detects prey such as a small fish or something passing by, it will use strong muscle contractions to shoot the tongue connected with the venom gland from its long tubular mouth at lightning speed and “close the gap”. nail” into the body, injecting poison into the prey. This venom will paralyze prey within seconds and die instantly. To prevent their prey from struggling, some species of snails have created a toxin that can reduce pain and anesthetize the prey’s nerves, making the prey feel no pain and slowly die without even realizing it. know. When the prey is fixed and no longer struggling, the conch will withdraw the “hook” (toothed tongue), pulling the paralyzed prey into the mouth. It’s worth noting that even when it’s not during mealtimes, if it feels threatened, the conch shells will shoot out without hesitation. So if you see brightly colored and beautiful cones on the beach, don’t stress. It came out by accident. Pick it up, especially the larger cone snails. This behavior can kill you because the conch’s nose can pierce the skin, gloves or wetsuit. Especially among cone snails, there is a species called Gastridium geographus, also known as geographical cone snail, killer snail, they are known as one of the most poisonous snails in the world, and one of the most dangerous snails in the world. marine animals that are extremely toxic to humans. One study estimated that this species alone caused 36 deaths. Symptoms of a snail sting include local pain, swelling, numbness, tingling, and vomiting. Symptoms may appear immediately or slowly over several days. In severe cases, muscle paralysis, vision changes and respiratory failure can lead to death. The various neurotoxins contained in cone snails are called cono toxins. In addition to being toxic to humans, in this venom mixture there are many beneficial substances, which can work accurately and quickly on the human nervous system without causing side effects. Therefore, this snail can also open up a new medical future for humans. For example, cono peptides have the potential to prevent spasticity caused by spinal cord injury and may help diagnose and treat small cell lung cancer. Conotoxins can immediately generate nerve signals that reduce heart rate or turn off pain receptors. Ziconotide isolated from it is used as an analgesic. It is said to be 1000 times more effective than morphine and not addictive. Conotoxin ACV1, isolated from Victoria cone cone in Australia, is more effective than morphine and Ziconotide, has a longer analgesic effect and is convenient to use without side effects. It has been shown to be very effective in the treatment of post-operative and neurological conditions, and even accelerates the recovery of nerve damage, and is expected to be developed as a treatment for anxiety. , Parkinson’s disease, muscle tension and hypertension.

Dolphins evolved from a terrestrial animal Dolphins evolved from a terrestrial animal Dolphins are mammals, closely related to whales, often living in the shallow seas of the continental shelf. Dolphins have the ability to understand simple human behavioral language. With their inherent magical ability, dolphins can understand and organize common objects into groups together. They understand both sounds and images, and even respond to images just like humans. Explaining this, scientists have confirmed that dolphins are the most intelligent animals in the world (while humans are only third in intelligence). Millions of years ago, the ancestor of the dolphin did not swim in the water as we know it today, but was a carnivore that lived entirely on land. However, about 50 million years ago, a mysterious event happened that forced them to adapt to the underwater environment, and gradually evolved into a mammal like today. Although they are considered extremely friendly animals, dolphins also have creepy habits, typically juggling their young out of the sea. This sounds like a very funny joke, but in reality, it is one of the ways adult males are killing their young so their mothers can return to mating. Dolphins can’t sleep for weeks at a time A recently published study has revealed the surprising ability of dolphins: They can stay awake for days or weeks at a time without sleep. So how can they survive without sleep? Dolphins possess a very special sleep mechanism, they can let half of their brain rest at a certain time while the other half is still awake – a process called “Unihemispheric sleep”. This special sleeping mechanism not only keeps dolphins from drowning, but also allows them to stay alert to any danger and even encourages brain development. Most dolphins don’t chew their food Dolphins do not chew food, or rather they cannot chew. Dolphin’s teeth are developed for the purpose of gripping prey. Sometimes they will shake or rub the food on the ocean floor to tear it into smaller pieces that are easier to swallow. One theory is that dolphins’ prey are mainly small fish, and they need to quickly grab the prey in their mouth before their meal can swim away. Skip the chewing process to make sure the prey can’t escape. Dolphins call each other by their own names, forming friendships through shared interests Researchers from the Universities of Bristol, Zurich and Western Australia have found that dolphins living in the Shark Bay area form friendships based on shared interests – in this case, the habit of using foam. sea ​​to hunt. This tool-using trait is found mainly in female dolphins, but by studying the behavior of a few expressed male dolphins, researchers have found a new discovery: The relationship of dolphins is formed through general tooling techniques. Dolphins have their own names and they will respond when called. Dolphins in each population possess their own “characteristic whistle”, just like a name, and other dolphins can use that distinctive whistle to get the attention of their mates. In fact, dolphins are also an extremely social species. The discovery opens up entirely new questions about how dolphins communicate and their “vocabulary,” and may reveal clues about the evolution of our own language skills. Dolphins use prey’s toxins as ‘addicts’ We know that puffer fish have strong toxins. Apparently dolphins know this too, but they use it for ‘high’ purposes. Usually, the puffer fish toxin is deadly. However, in small doses, it can act as a narcotic. The BBC once filmed a video in which dolphins gently play with a puffer fish for 20 to 30 minutes, then hang around and behave “weird”. Dolphins possess great “teamwork” ability A team of researchers from the University of Bristol recently discovered that male dolphins can work and work together as a team – an attribute previously thought to be unique to humans. Observing the behavior of male dolphins as they coordinated courtship with female pigs, the researchers saw cooperation rather than competitive behavior, which is particularly unusual in mate-finding in the animal kingdom.

This biome has a nutritional relationship to form a food web made up of many food chains and often there is only one leading predator in this food web, they play a very important role. important. This is a species (almost) not hunted and eaten by any species, for example: Tiger is the top predator in Asia, lion is the top animal in Africa, Komodo dragon dominates the island. Komodo, the Galapagos falcon is the top predator on the Galapagos Islands. Food net. Photo: Wiki Index But what happens when this top predator disappears from the food net or becomes weakened? This is a very interesting question! In fact, this hypothesis has happened many times and its devastating consequences are affecting the entire ecosystem. First, learn about the role of the top predator, which play an important role in maintaining ecological balance through controlling, overpowering, and regulating the numbers of other species. (from other predators to middlemen and also the flora at the bottom of the food web). Table top animals will help maintain ecological balance. Photo: Tran Vuong Fine Arts The top species will dominate other predators through … hunting on both sides, these predators play a role in controlling the number of species under its food chain, indirectly helping many other species and also protected flora populations. This protection not only takes place within the community, but also helps to control and repel exotic or invasive species outside the food web. The top predators also have an unwritten rule that they hunt only when hungry, not abuse their powers or abilities to slaughter smaller, weaker creatures. The end result is to create an ecological balance for the overall biome, so when the top predator is lost from the community, the community will fall into a disturbed and unbalanced state. . When the top species are gone There are many reasons that can cause the top species to be removed from the food net or lose the top position, one of the main reasons is due to human over hunting or the invasion of a birth. foreign objects are more overwhelming. The Everglades ecosystem, Florida, was once imbalanced by the dominant predator, the American short snout crocodile (Alligator mississippiensis), which was displaced by the exotic Burmese python (Python molurus bivittatus). Alligators are eaten by Burmese pythons. Photo: KPBS The flora and fauna here have been heavily damaged by this python, in contrast the number of Burmese pythons has increased exponentially (estimated from 30,000 to more than 300,000 individuals), making the import of this python species in the Ministry of the Interior. the US ban in January 2012. In Yellowstone National Park, starting in 1914, the wolves were massacred in an effort by Congress to protect the elk population as well as agriculture and cattle here. The results are not good either! The coyote heads the food net at Yellowstone. Photo: Untamed Science After the top predator was destroyed, the prairie wolves became the new top predator, but the problem was that the small grassland wolves were unable to take down their prey. big grass like moose. As a result, the elk population becomes crippled after the attacks, and the coyote wolves become more and more daring and more populous, killing smaller animals, eventually the people. gray wolves must be restored to maintain ecological balance. Another case took place in Australia. Here, the Dingo wild dog is a predator on the top ladder but has been severely reduced in number due to frequent crossbreeding with domestic dogs (they are listed as vulnerable species on the Red List. IUCN). Dingo wild dog. Photo: New Mails The decline in the power of the food-net leader has caused two invasive predators, the red fox and the wild cat, to self-destruct rodents and marsupials and birds to extinction (20 among the 30 extinct species in Australia are due to the predation of red foxes and feral cats). The above are just some examples of countless other cases that have happened in the past, through which we can see the indispensable role of the top and more conscious predator. in the protection of these animals.

This is also known as the “island law”, which is an ecological geographic law in evolutionary biology. In general, among animals that migrate from land to island, large animals tend to be smaller, and small animals tend to get bigger – this is called giantism. Island gigantism. For example, an extinct species of giant hutias in the Western Indian Ocean Islands is the largest known rodent. Its weight can reach a staggering level (about 200 kg), equivalent to that of an American black bear. Another famous example is the Dodo bird on the island of Mauritius. Due to the fact that the island’s environment is devoid of predators, they have also grown to form large and flightless. In contrast to island giantism, a condition where body size becomes smaller after immigration to an island is called Insular dwarfism. The most typical example is the dwarf elephant found many times on islands around the world. Elephants have always been known to be the largest terrestrial stump, but some dwarf elephants can only reach the size of a pig. Those who have read Odyssey will be impressed by Cyclops. According to speculation, the Cyclops prototype was a dwarf elephant. 2000 years ago, the Greeks probably excavated the remains of a dwarf elephant on an island near the Mediterranean Sea. Its skull size was almost twice that of a human skull. Perhaps it was because they had never seen an elephant, so the Greeks imagined it as the skull of a one-eyed giant, and related rumors and myths were born from this. Animal species that also dwarfed the island environment also included species such as dwarf mammoths, small hippos and Florida island deer, all of which were one size smaller than their terrestrial counterpart. Among them, the most extreme dwarf island fauna is the mini chameleon (Brookesia micra) of Hara Island in northeastern Madagascar, Africa. It is the smallest chameleon known to mankind, the largest one measuring no more than 3 cm. It is worth noting that this dwarfism does not only occur in ordinary animals. Even we humans cannot escape the law of the island. The pop culture dwarves are not unfounded, the “hobbits” are real. Flores island in Indonesia has an area of ​​only 14,000 square kilometers, but on this small island there used to be a small group of people who used to live. They are also “cursed” by dwarfism and this affects their stature. According to estimates from nine known fossils, this ancient human was only 1 to 1.2 meters tall and weighed about 25 kg. As we all know, the average 6-year-old modern person’s average height is more than 1.1 meters tall. This inevitably reminds people of the hobbits in “The Lord of the Rings”, so the ancient people on Flores were also known as “hobbits”. From a taxonomic point of view, the Flores belong to the same genus as us. Hence, they are also the smallest known human species. The ancestor of the Flores was Homo erectus. About 200,000 years ago or earlier, they moved on to Flores Island. Compared to the mainland, the island’s resources were very limited and the Homo erectus people were often hungry due to lack of food. If the people are short, there is a better chance of survival because they need to eat less. As a result, the dwarf gene is passed from generation to generation, and eventually develops into Floresians. Biological evolution has shown more than once that some strange things will happen on the islands. And from the changes in body shape of the other animals on Flores Island, you can feel the power of the law of the island. At that time, on the island there was a species of elephant named Stegodon florensis, only 1.5m high and weighing no more than 800kg. Their land-based compatriot is the elephant Stegodon zdanskyi. They are stronger and more powerful than modern African elephants, this species is about 3.8 meters tall and weighs 12 tons. But not all of the animals on this island have been reduced to the same size as the Flores and the Stegodon florensis, in fact, the small terrestrial animals that migrate here will achieve a Giant size beyond imagination. The most typical example is the Flores Giant Rat, since without natural predators, they are not even afraid of humans. Of course, this giant rat does not threaten the survival of the Flores Island biological population. Except for some insects, the giant rat Flores is mostly vegetarian. It can be said that biological evolution on the islands took place in a very strange way. Therefore, scientists always think of the first word “island” when discovering creatures with anomalous body shape. So what is the factor that causes the animals on the island to change their body shape? For many years, scientists have always wanted to summarize the general nature of the rules on the island, and try to solve that mystery. The first person to try to explain this phenomenon was a biologist named J. Bristol Foster. Therefore, this ecological geophysical law is also known as “Ford’s Law”. In 1964, his dissertation compared 116 island species with terrestrial species and plotted them in a table. In an article titled “Mammal Evolution on Islands,” Foster said that among the new “inhabitants” of the island, rodents tend to grow larger. Predators and ungulates will tend to be dwarfed. In general, large terrestrial species will be smaller and smaller land species larger on islands. In this regard, Foster also provided some tentative explanations. The number of species on the islands is much less than on the mainland, and the number of predators and competitors will decrease accordingly. This seems to be an advantage for small rodents. Because they do not have a predator, they always have a sufficient source of food and can control their fertility rate well. But hippos, deer and other large animals cannot do this. A lack of predators would also mean an overabundance and a shortage of food. Consequently, the smaller members of the population will have a higher survival rate and begin to affect the entire population. They grow from generation to generation and their sizes are getting smaller and smaller. Foster’s paper is simple, but at the time it aroused strong interest in the scientific community. Thereafter, more extensive research was conducted on the island’s organisms, and the island law was a little more refined. In fact, large organisms have more food choices and more easily control other species. Small organisms, on the other hand, require fewer resources, shorter reproductive cycles, and adapt faster. Therefore, in the island ecological environment, where every aspect is limited, these factors are very important and have special effects. Subsequent studies also found that the speed at which the island’s animals change body shape was indeed staggering. 24 km from the French coast, there is an island named Jersey. About 6000 years ago, the deer came here and completely isolated from the mainland. As a result, in this short time of thousands of years, the red deer on the island has shrunk by 1/6 of that of the people on the mainland. Fossil records show that it only took 5,000 years to dwarf a population of elephants from 4 meters in height to about 1 meter. However, it should be noted that the island laws are only a general model of evolution, not absolute law. The environment on an island includes many different factors, such as the size of the island, climate, natural history, habitat, biological relationships, etc.These factors will also affect the size of the island. animals on the island to a certain extent.

The extinct prehistoric mammoth was believed to be prehistoric human prey. A controversial new study found that the first humans were large predators who took down prey with skilled hunting skills. In a new research paper, the scientists argue that humans and close relatives have been adept hunters from a very early age, starting at least 2 million years ago. Miki Ben-Dor and Ran Barkai, researchers at Tel Aviv University in Israel, and Raphael Sirtoli, a PhD student at Minho University in Portugal. “Until now, efforts to recreate the Stone Age human diet have been based mainly on comparison with 20th century hunter-gatherer societies,” says Ben-Dor. Of course, this comparison is lame, because 2 million years ago, hunter-gatherer societies could hunt and consume elephants and other large animals, while hunter-gatherers today. It can’t be like that. The whole ecosystem has changed, and the conditions cannot be compared. ” Scary evidence Fossil evidence from earliest human ancestors is scarce. But based on archaeological evidence, Ben-Dor said, it was clear that Homo sapiens and their close relatives ate anything that was edible. But how much of their diet consists of plants versus animals is the bottom line. Many animals that are considered omnivores actually have the diet in one way or another. Chimpanzees, for example, are technically omnivores, but meat makes up only about 6% of their diet. Dogs and wolves are predominantly carnivorous but sometimes also nibble on grain, leading to a debate over whether they should be classified as omnivores or predators. According to Ben-Dor, ancient humans Homo habilis ate meat at least 2.6 million years ago. Another primitive human species, Homo erectus, appeared to be an avid carnivore 1.8 million years ago; Their teeth and intestines shrank compared to their previous ancestors, adapted to digest meat instead of plants, and it used stone tools capable of grinding meat. Ben-Dor and Barkai argue in their paper, published in the American Journal of Physical Anthropology, that meat is not just a reward for these humans and the early Homo sapiens. Instead, the authors believe, large animals weighing more than 1,000 kg, such as elephants, hippos and rhinos … make up the bulk of the human diet. The elephants 500,000 years ago could weigh 12 tons, compared with 4 to 6 tons today. Eat a lot of meat, human brain evolution? According to the researchers, these animals can eat fatty meat, which is very suitable to feed the energy-hungry human brain. The authors argued in another recent article that hunting large prey could be the driving force behind human brain evolution. However, the idea is controversial, and researchers disagree on how huge amounts of meat would be useful to hunter-gatherers in the days before refrigeration, as well as about ancient humans skilled in taking down prey that other predators like lions, struggled to defeat. “There are some archaeologists who say, they hunted elephants once, but it’s like a once in a lifetime hunt; that’s what grandparents often tell their children,” John said. “There are people who say that elephant meat can last a long time without preserving, but it’s part of their routine,” said Hawks, a paleontologist at the University of Wisconsin-Madison. important to them. ‘” Ben-Dor and his colleagues wrote in their article that eating large, fatty animals would be a benefit to humankind at the earliest, because losing so many calories on a hunting trip – instead of repeatedly trying to stalk smaller prey. Humans exhibit this high-fat adaptation, researchers say. Archeologically speaking, it was difficult to classify humans and their relatives as carnivores before about 50,000 years ago. That’s because the only reliable biochemical way to distinguish an animal as the top predator or lower in the food chain is a method known as stable nitrogen isotope analysis, requires collagen testing for molecules that are taken orally into the body. Despite the limited evidence of humankind’s early evolution, the researchers say, much remains to be done to prove whether the human ancestor was indeed carnivores. This could include more research on the abundance of animals of different sizes during the Pleistocene, exploring genetic changes over time that could alter the digestibility of species. Different human feeds and comparison of prey size trends over time.
