Revealing the live frog jumping out of the stone

  A construction worker demolished an old building and found a time capsule. When he opened the time capsule, a green frog jumped out, singing and dancing in front of him…
  This is a story told by Bugs Bunny to children in the classic cartoon “The 1001st Legend of Bugs Bunny”. Maybe you think this is just an animation and has nothing to do with reality? In fact, many places in the world have recorded legends about toads, frogs, and other small animals being wrapped in rocks and still alive a long time later.
Frog living in the stone

  In 1865, people in Hartlepool, England, were talking about a strange thing. A local farmer was digging foundations to build a house. When he dug to a depth of 8 meters, his shovel shoveled a stone. A strange sound came from the stone. The farmer took out the stone, found something and smashed the stone, and found that there was a hole in it. Then, a frog the size of a human fist jumped out of the hole.
  This frog was not like the British frog of the time. Its front paws were bent inward, its hind limbs were very long, and its appearance was very strange. At first, the frog’s skin was pale white and breathing was slightly difficult. Then it turned olive brown and its eyes became unusually bright. When the farmer tried to touch it with a wooden stick, it started to make some noises. The farmer checked his mouth and found that his mouth was closed tightly, and the sound came from his nose.
  During the same period, an article in the journal “American Scientist” also recorded a similar incident. An American silver miner found a toad in a round stone with a diameter of 60 cm. This toad is 50 cm long, fat and fat. Its eyes are very big, as big as a one-cent coin, bigger than the eyes of any toad. The silver miner tried to poke the frog with a stick to make it jump, but it ignored it.
  Until the 20th century, such stories still happened. During 1945, a group of British soldiers used explosives to blow up rocks while building roads. After an explosion, a British soldier noticed a rock that was blown up. He saw a large toad in the cave of the rock and a lizard at least 2 meters in length beside it. Surprisingly, They are all alive. When the rock on which they lived was pried apart, they were like slaves who had been imprisoned for many years. After being released, they were immediately full of vitality and jumped up and fled into the jungle.
  Since the 15th century, Hikari reports have recorded more than 200 similar stories. People who discovered these creatures almost always said that the stones did not have any holes or cracks for these animals to penetrate. Therefore, these animals should have been dormant for several years or even thousands of years.
  However, is this really possible?
How long can animals sleep

  It is difficult to verify this issue from historical data, because most of these stories are from news reports in the 18th and 19th centuries, and are compiled by reporters after interviews, and are not primary sources. But we can think from another perspective, are there amphibians, or are there animals that can survive a long time without eating or drinking?
  When faced with extreme environments, animals do have a special way of coping-sleep. When food and water are in short supply, animals will slow down their metabolism and chemical reactions in the body, their breathing and heartbeat will slow down, and their body temperature will drop.
  Frogs and toads can also stay inactive, minimize energy consumption and enter a dormant state. At this time, in order to maintain the ongoing metabolic activities in the body, animals have to rely on body fat as the main source of energy, and the protein of muscle tissue will also be broken down into amino acids, which become a secondary source of energy after being oxidized. These chemical reactions allow animals to survive the dormant period safely. However, the fat of animals is limited. Studies have shown that the longest time for a frog to hibernate is about half a year, and in summer, it can last for about 10 months. Once this time is exceeded, the frog will starve to death.
  Therefore, if we want to explain that these animals can live in rocks for decades, hundreds or even thousands of years, then frogs must not have any metabolic activities and consume any energy of their own. is it possible?
  If all metabolic activities tend to zero and the body does not produce any heat, it is basically equivalent to death. Chemically and biologically, the animal body at this time is similar to a cold corpse. In the case of zero metabolism, the cell enters the autolysis process, the cell’s own enzymes will break down the cell tissue, and the immune system will stop working. Soon, in the body, the only activity will be bacteria. Usually, bacteria can play an important role in helping, such as fighting infection and helping digestion. But when the animal dies, anaerobic bacteria will begin to break down the animal’s body tissue. In a closed environment, bacteria will eventually die, but they will starve to death only after all available resources have been consumed. At this time, the frog’s body was also broken down. Therefore, if an animal’s metabolism stops, its body tissues will be broken down and it is impossible to survive for that long.
  However, we can imagine another situation. If there is a frog that is now extinct on the earth, when their metabolism stops, the body can avoid self-decomposition, or can avoid being destroyed by bacteria, without any consumption of body fat and protein, they may Jump out? From these stories, it can be seen that these animals can recover from the dormant state immediately after the stone is broken. This conversion of different body states requires huge energy consumption. And when you are in a physiologically dead state, it is difficult to suddenly trigger the rapid response of the body’s metabolism.
  Therefore, a large part of the story of a frog jumping out of a rock should be false. Perhaps it was just a mistake made by the eyewitness, or it was fabricated. From a scientific point of view, such a strange phenomenon does not exist.
What scientific experiments can tell us

  In fact, there is another way to find the answer. If a person has enough patience to experiment, put different types of frogs and toads into various rocks, and after a few years, see if they can still survive, you can know the answer.
  Some researchers have already done this. In 1825, Buckland, a professor at Oxford University in England, also heard of these strange stories. He did a simple verification experiment and buried 24 toads underground and placed them in a rock composed of sandstone or limestone. Then he Seal the rocks with glass windows. A year later, he dug up these rocks. The results showed that all the frogs buried in the sandstone were dead and their bodies decayed, while those in the oxygenated limestone successfully entered a dormant state and were still alive when they were discovered, even though their weight had dropped by half. .
  In order to better observe, Buckland buried the survivors in the soil and observed for another year. A year later, the frogs all died. This experiment shows that frogs may be able to stay in aerobic rocks for a year, but for too long it will exceed their tolerance. There are many similar experiments. So far, no experiment has proved that frogs can sleep in rocks for several years.
  Therefore, just like astronauts who have lived in space, rarely believe in aliens, and no paleontologist or geologist believes that such strange things that break common sense will happen. When you hear a strange event, if the story does not have a reliable source, you have reasons to doubt and use scientific methods to find the correct answer.
