Where "human, will go", has been a lot of science enthusiasts interested in the topic. Field of study of the origin of life at the highest level — — the 14th International Congress of recent origin of life, for the first time held at Tsinghua University in Beijing, China. Life science's top scientists, and the public had a close dialogue.
■ Evolution is a truth
Many people often have such thoughts, man is but a history of a moment, the future will gradually disappear, or would like a sudden death like dinosaurs? "I hope not so". United States National Academy of Sciences, academician, palaeontological research expert J.WilliamSchopf believes that the general situation, human life is probably the most 1000 million years. But don't forget that mankind invented the atomic bomb, it would also destroy the human race. He hoped that the human can use wisdom, can not use these destroyed their own weapons.
He said that now people have the wisdom to be able to control the length of life. General animal, they perish because of disease, but humans can heal their illnesses. Some animals perish, because the Earth's environment has changed, people are too cold environment, you can light the stove, heating; too hot, you can use the fan and air conditioning. Now humanity can use biological gene changes, control the length of your life and evolution. "Maybe our new age people, able to maintain a long time, the ancestors of than before. ”
Schopf said, no one knows where the origin of life, but we know that life at 35 million years ago has begun. Some scientists say, life is from space passes on, this is possible. If there is a belt from outer space, the outer space planet planet Earth with our environment must be the same.
Schopf stressed that Darwin's theory of evolution is 100 years ago, 100 years, countless tested the Darwin theory. "Evolution is a truth. We have two ways to study the evolution of life, from different fossils found life in a step by step; at the same time, we study the biology, now also find them in a step by step evolution. ”
■ There is on Earth may only exist human
Many facts indicate that there is no evidence that biological diversity is in, but there are various causes of extinction of species constantly.
2003 first prize winners of national natural science foundation of China, Chinese Academy of Sciences Institute of paleontology junyuan said, now, man is the largest, but also the most vulnerable species.
Life history tells us that the seemingly large species, often in natural environment changes first from the stage of history. Dinosaurs ruled the 1 billion years in the Mesozoic era, humanity today is like a dinosaur, if Earth into extreme environment, then we are likely to be among the first to exit the stage of history. "Mankind is not possible to leave the survival of other species, we individually and the other species is the companionship of brothers and sisters, isn't likely to survive alone. ”
Junyuan said that humanity as unique a thought on Earth, wise life, start with a lot of confusion.
These puzzles are mainly include the following basic questions: we come from?: why are we here? in Darwin, most people believe that human existence or surrounding species exist, because of the supernatural or God.
The Earth is a stage, a life in non-stop performance on the stage, performing the billions of years, but this stage has no audience, no one knows, Darwin, the origin of species ", just like how to look at the life of a guide, the drama of humanity truly becomes a serious audience, understand and explore how the play is staged.
■ Expectations and the intelligent life dialogue
One of the world's top scientists, 1967 Nobel Chemistry Prize winner Professor ManfredEigen said that to understand the origin of life, it is first necessary to understand what science is and what can be seen, now we already know the evolutionary process.
Junyuan said the study's significance to life, also possible to search for extraterrestrial life, especially intelligent life outside Earth provides a scientific perspective. He said that the origin of life, there are three basic stages: life's original origin, complex origin of life, and an intelligent origin of life. "The Earth in only less than a billion years began the most primitive life, but spent 40 million years or more time to appear complicated life. "He said.
Junyuan believes that life in the universe of many star systems may occur, as other life relying on stellar systems do not need to have a long life, as long as ten billion years is enough, but the emergence of complex life, must have 40 million years or more.
Junyuan said, human intelligence and ability also is very naive, if you count the Earth into 24 hours of life, human beings with a seconds are not. At present, the human search for extraterrestrial intelligent life have a long way to go. "Our species has 2 million years, nature has left our life may or may not be very long, really want to talk to intelligent life in space, it is possible to enter into dialogue with the world, we have a treat in the biology of development, life changed a bit longer. ”
