origin of life bbc

Life (also known as Life Pulse) was a ten-episode documentary series produced by the BBC. It began airing on BBC television on October 12, 2009. The production took four years, and all of them were filmed in high definition. Each episode was 50 minutes, plus 10 minutes of shooting for a total of 60 minutes. Although there were reports that it cost 10 million pounds, the BBC did not officially confirm it. The year 2009 was the 200th anniversary of Charles Darwin's birth and the 150th anniversary of the publication of Origin of Species. The documentary was dedicated to the memory and tried to show the variety of species in nature and their magical survival skills in order to adapt to the environment. It told 130 incredible stories about nature. It used cutting-edge photography technology to capture many amazing scenes, such as the complex water dance of courtship birds, the fish flying with fins to avoid predators, etc. It showed the survival tactics of animals and plants, as well as how creatures overcome enemies and environmental challenges under extreme pressure and expand their limits. For example, the first episode showed the behaviors of foraging, hunting, courtship, and brooding in the animal world, such as the cooperative hunting of broad-nosed dolphins in the Gulf of Orlando, the opening of nuts by Brazilian capuchins with stones, etc. There were also species that protected their offspring, such as strawberry poison dart frogs protecting tadpoles, and Pacific giant octopuses holding on to their eggs until they starved to death.

There were many theories regarding the origin of life. One view is that life may have originated from underwater hot springs. Earth's early oceans were more "passionate". Underwater volcanoes and hot springs spewed hot liquids. The temperature here was high (about 300 - 400 degrees Celsius), it was in a strong acid and strong base zone, and the water was in a supercritical state. However, it was full of vitality. Some fish, shrimp, and algae thrived here. According to this, scientists speculated that this might be the birthplace of life. There was also a view that life originated from the primitive oceans on Earth. The gases in the primitive atmosphere, such as methane, nitrogen, and carbon dioxide, synthesized small molecular organic compounds, such as fatty acid, under the effects of violet light and lightning. The chemical reactions in the water and the rock sphere may also promote the formation of fatty acid. These fatty acid flowed to the sea, and the ocean, which was similar to the "soup", provided the possibility of the origin of life. In 1953, the Miller-Urey experiment simulated the primitive Earth's atmospheric environment. Through gas circulation and electric sparks to simulate thunder and lightning, it produced small biological molecules such as acids, proving that under primitive conditions, minerals could be transformed into basic organic substances needed for life. This supported the theory that life originated from the primitive oceans of Earth. In addition, there were also outsiders who believed that the basic elements of life came from outer space. When meteorites passed through space, they might carry organic matter (including acids) from other planets or interstellar space. When the meteorites hit Earth, these organic matter were released onto Earth. Under some coincidences, about 3.6 billion or 3.8 billion years ago, the world's first life was born in the underwater crater. "The Island of Life" is also a wonderful novel.

Life was the carrier through which energy flowed, and everything in the universe was the carrier through which energy flowed. It was just that different carriers had a huge difference in scale. From different perspectives, the origin of life also had different understandings. On the philosophical level, it might be related to people's exploration of the meaning of their own existence, such as being true to themselves, being compassionate, opening their hearts, etc., which were all insights in the process of exploring the origin of life. In the field of investment, life economics advocated that investment should return to the origin of life and use life as the investment target. However, there was no specific physical content of the origin of life. In addition, cultivating one's body and keeping one's heart clear and pure was also seen as guarding the source of life.

If it refers to Deng Wanfa's poem "The Source of Life", there is no commercial price; If it refers to the hand-carved "Source of Life" bracelet of olive stone, the price is 62 yuan; If it refers to the single-seed "Source of Life" of olive stone, the price is 15.11 yuan; If it refers to the natural soda water of Wajaluna Wudalianchi, the specific price is not mentioned in the article, only that the live broadcast room is cheaper than the supermarket; If it refers to the extremely expensive natural water, a whole box of it costs 0.6625 yuan per bottle. If it was a fake medicine named " Source of Life," there was no legal price and it was considered fraud. " The Island of Life " is also a wonderful novel. Everyone is welcome to read it!

As for the Chinese version of the documentary, the current reference only mentioned the existence of the Mandarin version of the documentary on human evolution, but did not provide more specific information about the documentary. Therefore, he was unable to tell them exactly how to obtain the Chinese version of the documentary " The Origin of Life." " The Island of Life " is also a wonderful novel.

There were many different views regarding the origin of life. One view believed that the basic elements of life were first born in the atmosphere, which could be called the internal view; the other view believed that the basic elements of life came from outer space, which was the external view. According to current scientific understanding, the origin of life was a complex chemical evolution process. It was generally believed to have occurred in the primitive oceans on Earth, where a series of chemical reactions formed self-replicating molecules that eventually evolved into today's diverse life forms. This process involved the formation of organic molecules, the emergence of primitive cells and other early forms of life, as well as natural selection and evolutionary mechanisms. The Barberton Makunwa Mountains (Barberton Greenstone Belt) in northeastern South Africa was also regarded as the birthplace of life on Earth. It represented the most well-preserved volcanic and Sedimentary Rock sequences, dating back to 3.6 billion to 3.25 billion years ago. It formed a variety of information bases on surface rocks, meteorite impacts, volcanism, continental formation processes, and early life environments. In 2015, a team of German and Swiss scientists found evidence of more than 3 billion years of microscopic life in the surface cavity of the area. "The Island of Life" is also a wonderful novel.

There were currently two mainstream views in the scientific community regarding the origin of life on Earth. One was the theory that the basic elements of life came from outer space. When meteorites passed through space, they might have carried organic substances (such as acids) from other planets or interstellar space. When the meteorites hit Earth, these organic substances were released to Earth. Under certain coincidences, these acids gathered in the crater of the seabed about 3.6 billion or 3.8 billion years ago to form the world's first life. This life had the ability to obtain material and energy from the outside world (survival) and self-reproduction. For example, in 2009, American scientists discovered gly on a comet, which provided some evidence for the alien theory. The other theory was that the basic elements of life were first born in the atmosphere. During the early days of the Earth, gases such as methane, nitrogen, and carbon dioxide in the primitive atmosphere might have synthesized small molecular organic compounds such as aa under the effects of violet rays and lightning. The chemical reactions in the water and the rock sphere might also promote the formation of aa, which flowed into the sea. In 1953, American scientists Miller and Urey conducted an experiment to simulate the atmospheric environment of the primitive Earth. Through the circulation of a mixture of methane, hydrogen, and hydrogen with water, coupled with electric sparks to simulate thunder and lightning, a week later, the device produced small biological molecules such as the most basic of life, four of which were the most basic of life. This experiment provided strong support for the theory of internal growth. In addition, the hypothesis of the underwater hot springs was also related to the origin of life. The early oceans of Earth formed a high-temperature, strong acid and strong base environment due to the activity of underwater volcanoes and hot springs. However, extreme thermophiles were found here. This kind of bacteria appeared on Earth about 3.5 billion years ago and may be the common ancestor of all living things on Earth. Therefore, scientists speculated that this may be the place where life was born. "The Island of Life" is also a wonderful novel. Everyone is welcome to read it!

According to the current scientific understanding, life originated on Earth, or more precisely, it originated from the primitive oceans on Earth. From the perspective of chemical evolution, molecules that could self-replicate were formed through a series of chemical reactions in the primitive ocean, eventually evolving into today's diverse life forms. This process involved the formation of organic molecules, the emergence of early forms of life (such as primitive cells), and the mechanisms of natural selection and evolution. In addition, the undersea hot springs were also considered an important place for the origin of life. In 1977, the United States 'Alvin manned submarine discovered many creatures around the hot spring at a depth of 2500 meters. Here, the seawater seeped into the crust along the cracks and was heated up, then dissolved the sulfur and metal elements in the rocks to form a hot liquid. The hot springs were different from the seawater in terms of acid and base, and the seawater here was in a state of high temperature and high pressure, causing water, carbon dioxide and other substances to exist in a critical state. The scientists speculated that at the beginning of the Earth's formation, the environment of high temperature, high pressure, strong acid and strong base near the underwater hot spring mouth would catalyze the organic matter into organic matter, and produce organic molecules such as the essential organic molecules of life. At the same time, the rocks collected from here had small holes with a diameter of about 100 millimeters (just the size of a single cell). These holes could accumulate high-intensity ion concentration differences to promote the production of energy by ATP-synthesizing, so that the organic matter in the holes could carry out life activities.
