Evolution of Ancient Creatures
The evolutionary process of ancient creatures was long and complicated. They had gone through many important stages: 1. [Origin of Life: It is generally believed that life evolved from organic to organic chemicals.] The Earth's primitive atmosphere was rich in methane, nitrogen, carbon dioxide, water vapor, and so on. Under the effect of high energy (violet light, lightning, and high temperature), it first synthesized small molecular organic compounds such as fatty acid and fatty acid, which were further combined into more complex organic substances such as protein and nuclear acid. Finally, it produced a multi-molecular system that could self-renew and had a complex structure. Primitive life was born from this. Fossilized thread-like bacteria found in the 3.5 billion-year-old Valauna Group in Australia suggest that life originated about 1.1 billion years after the formation of the Earth. Primitive life was of the anerotroph and heterotroph types. 2. [Prokarytes appear]: The first life forms were non-cellular. In order to ensure the exchange of materials, they formed cell membranes during evolution, and prokarytes with cell structures appeared. The earliest reliable fossil with a cell structure found on Earth was the fossil of the thread-like bacteria in the Valauna group. 3. Formation of an algae-bacteria ecosystem: The earliest heterotroph protocaryote bacteria that appeared on Earth continued to differentiate and develop, resulting in the emergence of autotroph protocaryotes, blue-green algae. The blue-green algae could carry out photosynthesis to synthesize organic nutrients. Cyanacea and bacteria, as synthesizing and decomposing agents, formed a complete ecosystem. From heterotrophy to autotrophy was a major leap in early biological evolution. Cyanacea was the earliest organism that released oxygen. It increased the concentration of oxygen in the earth's primitive atmosphere and formed an oxygen atmosphere. The high-altitude oxygen layer absorbed the ultra-violet radiation and changed the ecological environment. The organism changed from being an anoxide-loving organism to an oxide-loving organism and improved the efficiency of energy metabolism. Fossilized bacteria and blue-green algae about 2 billion years old were found in the Ganflin Formation in Canada. 4. [Eukaryote Birth: The transition from prokaryota to eukaryota is the turning point of biological evolution from simple to complex.] Procaryotes had no nuclear membrane and organelle, and their structure was simple. Eukaryotes had a nuclear membrane, which was divided into a nucleus and a plasma. The nucleus became the center of inheritance, and the plasma became the center of metabolism. The regeneration of the cell structure increased the variation, allowing eukaryota to develop into an advanced system. It has been discovered that procaryotic blue-green algae and eukaryotic green algae were found in the Baiyun of the Beck Spring Formation in California, USA, about 1.3 billion years ago. Green algae were the earliest organisms with eukaryons. 5. [Animal Division and Development: With the emergence of eukaryons, animals and plants began to develop.] The earliest animal fossil in the history of the earth was the Edikara Fauna in Australia 600 - 700 million years ago, including coelenterate, annelid, arthropod, etc. From the level of animal division, it was already a later type, not the original representative of animals. The emergence of animals formed a new three-pole ecosystem. Green plants (eukaryons and prokaryons) were producers, bacteria and fungi were decomposing, and animals were consumers.
