the origin of life from nonliving matter. specifically : a theory in the evolution of early life on earth: organic molecules and subsequent simple life forms first originated from inorganic substances.
自然發生論，或者說生命起源[2][3][4][a]，指的是自然歷程中無生命物質如何演變為有機分子乃至生命的學說[5]:vi[3][6][7]:47。目前普遍接受的假設是，地球上從非生物到生物的過渡不是一個單一的事件，而是一個演化的過程（即一個複雜性逐漸增加的過程），其中涉及到宜居星球的形成、有機分子的前生物合成、可自我複製、自組裝、自催化的分子，及細胞膜的出現。[8][9][10]對這一過程的不同階段，存在許多假說。[11]
Please explain abiogenesis to me. (ChatGPT, 2024-6-6)
Abiogenesis is the scientific hypothesis that explains the origin of life on Earth from non-living matter. This concept suggests that life arose naturally through a series of chemical processes that resulted in the formation of simple organic molecules, which eventually led to more complex molecules and the first primitive life forms.
Key points of abiogenesis include:
1. **Primitive Earth Conditions**: Abiogenesis likely occurred on the early Earth, which had a very different environment compared to today, with a mixture of gases such as methane, ammonia, water vapor, and hydrogen.
2. **Chemical Reactions**: Under the conditions of early Earth, energy sources such as lightning, ultraviolet radiation, and volcanic activity could have driven chemical reactions among these simple molecules, leading to the formation of more complex organic compounds, such as amino acids and nucleotides.
3. **Formation of Simple Life**: These organic compounds could have accumulated in the "primordial soup," a body of water containing these molecules, where they eventually combined to form more complex structures like proteins and nucleic acids.
4. **Self-Replication**: At some point, these complex molecules developed the ability to replicate themselves, a key characteristic of life. The first self-replicating molecules were likely RNA, which can store genetic information and catalyze chemical reactions.
5. **Evolution of Life**: Through natural selection and evolution, these primitive life forms became more complex over time, eventually leading to the diversity of life we see today.
Abiogenesis remains a hypothesis because, while there is substantial evidence supporting the chemical processes that could lead to the formation of life, the exact pathway and conditions that led to the first life forms on Earth are still not fully understood.
