What magical skills have pigs developed that have evolved on earth for 40 million years?


Pig is one of the common poultry in daily life.Although we often eat pork, do we really know anything about pigs?For the concept of pigs, many people may use “gluttonous and lazy” four words to describe.But are pigs really as we see them?Pigs have been able to survive on earth for 40 million years, and must have many skills that we don’t know about.Here we take a closer look at how pigs have evolved over 40 million years on Earth.We now see a pig is a lazy, lethargic, lying in the pen every day to either eat or sleep.But it wasn’t like that a long time ago.Pigs According to biologists, pigs are older than humans.It has evolved through the Miocene, Pliocene, Pleistocene and Holocene epochs for at least 40 million years.Pigs are now found all over the world and have become one of the most common mammals.The ancestors of pigs are ancient giant porcine creatures that lived 40 million years ago.They are huge and can even grow to the size of a bison in a short time.The most famous giant pig in Asia is the “unicorn” kuban pig.Large Kuban pigs are more than 2.5 meters long and 1.2 meters tall at the shoulder, and can weigh between 500 and 850 kilograms.They didn’t look too different from today’s pigs.It’s just that the Cuban pig has one more “horn” on its head than today’s pigs.It’s a bony protuberant in the midline of the skull, just above the eyes, like a unicorn.Scientists speculate that the horns on the Kuban’s head were used for fighting to gain maximum dominance and mating rights in the population.Pigs in Asia were first domesticated by our ancestors about 8,000 years ago.Humans lived by hunting and gathering.As humans’ most important source of meat, pigs were first raised by our ancestors when they found domestication more convenient than hunting.Zodiac pigs have existed throughout our evolutionary history.In ancient times, raising pigs was an indicator of a family’s wealth.So the pig represents wealth and ease of life.In ancient times, the pig was also included in the zodiac sequence.What skills do pigs have?According to the origin of pigs introduced above, we can know that pigs in ancient times did not have sharp teeth and claws like pigs today.At that time, pigs were very tough creatures.It’s huge, and it’s incredibly heavy.Their huge teeth and horns help them win in battle.In daily life, there have been many cases of wild boar wounding people outdoors.The boar’s secret weapon is its nose.You can imagine a pig’s nose is like a human hand.The nose helps them push and arch objects.This is what we now call being poked by a pig.Noses instead of hands.And the pig’s secret weapon, the nose, is not only an invisible hand, but also a scent that many other animals can’t smell.Unlike the human olfactory system, 7 percent of the pig’s brain is used to process odors, 700 times more than in humans.The truffle-hunting nose of pigs not only helps them find food but also promotes pig reproduction.In France, people hunt for truffles in the forest with the help of well-trained domestic pigs.Pig noses rely on their keen sense of smell, sniffing here and there, to find truffles buried in the soil.In ancient times, when food was scarce and natural environments were harsh, wild boars relied on their excellent olfactory system to find food that other animals could not find.Pigs also rely on their noses for reproduction.During rutting, the boar will smell the special scent of the sow and frantically salivate to attract her.When a sow smells the saliva of a boar, she will choose the scent of the desired boar and follow the scent.After the boars have defeated other competitors, the sows that scent together can mate.The pig is also a powerful animal with a secret weapon.Their diet is simple but not homogeneous.They can eat grass or meat.Eating any kind of grass or meat will keep them alive. They are not picky eaters.Pigs are easier to survive than animals that are less aggressive but have a single source of food.It’s not for nothing that pigs have been able to thrive and evolve for more than 4,000 years in a world of complex dangers.Are pigs really as stupid as we think they are?We think of pigs as lazy, stupid, weak, dirty, it seems that all bad adjectives are associated with them.But are they really?Facts always differ greatly from imagination.At least the fact that pigs have survived in nature for more than 4,000 years proves that they are powerful and have nothing to do with stupidity.Pigs indeed, pigs in real life are very clever.”Stupid pig stupid pig” is definitely a misunderstanding of them.Zoologists have long studied pig behavior, observing three distinct behaviors in pigs: exploratory behavior, deviant behavior and aftereffect behavior.Exploration behavior, as the name implies, is a pig’s performance of exploring and observing things around.When a pig arrives in a strange place, it constantly uses its nose to touch things around it, and uses its keen sense of smell to smell the air.In order to understand their environment.Most of the abnormal behaviors of pigs are abnormal behaviors of pigs.There have been farmers found that a sow will be kept in a pen for a long time, pigs will produce a lot of abnormal behavior.Such as biting pigsty railings, biting faucet switches and so on.Aftereffect means they have a high capacity for learning.By feeding over a long period of time, it will remember the location, time or other feeding conditions of its owner.All of these behaviors suggest that pigs are not as stupid as we know them to be.The fact that they have survived on earth longer than humans suggests that pigs are a species that has not been eliminated by evolution.Conclusion Pigs are one of the animals that have survived after being domesticated and released into the wild.It’s not as dumb as we think it is, it’s very smart.As one of nature’s most successful mammals, pigs roam the globe, adapting to their environment in a variety of ways.Over the course of 4,000 years of evolution, pigs have evolved into what we now see in our lives.Despite the dramatic decline in wild boar populations due to human hunting, we should respect the evolutionary form of every creature and always remember that wild boar is not equal to domestic pig.
