The learning techniques for evolution in high school biology were as follows: ** 1. Master the laws of biological evolution ** 1. ** Follow the evolutionary trend ** - Biological evolution had a trend from simple to complex, from low to high, from aquatic to terrestrial. Understanding this law would help to sort out the context of biological evolution. For example, the evolution from single-celled organisms to multicellularized organisms, and the evolution from inverted animals to inverted animals, all reflected this trend from simple to complex, from low to high. - In the study of paleology, fossils in different layers showed this evolutionary law. The structure of fossil organisms in ancient layers was simple, while the structure of fossil organisms in newer layers was more complicated. 2. ** Rules of adaptation and selection ** - Biological evolution was the result of the interaction between living things and the environment. Living things had to adapt to the environment in order to survive and reproduce. Those who were not adapted were eliminated. This was natural selection. For example, before the industrial revolution, the trunks in Manchester, England, were covered with light-colored lichen. The light-colored beetle moths were similar in color to the environment and were not easily discovered by natural enemies. After the industrial revolution, environmental pollution made the trunks black, and the number of dark-colored beetle moths increased because they were more adapted to the environment. ** 2. Learn to observe and compare biological evolution related knowledge ** 1. ** Observing evidence of evolution ** - Observing the evidence of biological evolution was an important part of understanding evolution. Fossil was the most direct evidence of biological evolution. By observing the fossils in different layers, one could understand the characteristics of the structure of organisms in different periods and speculate the evolutionary relationship of organisms. For example, the archaeopteryx fossil had both bird characteristics (such as feathers) and reptile characteristics (such as teeth, claws, etc.), indicating that birds might have evolved from reptiles. - Observing the same organs of living creatures also helped to understand evolution. For example, although the upper limbs of humans, the wings of birds, and the winged hands of bats had different appearances and functions, their anatomical structures were similar. They all developed from the same skeletal structure, which meant that these creatures had a common ancestor. During the evolution process, they gradually developed differences in function and appearance due to adapting to different environments. 2. ** Comparing Evolution-related Concepts and Phenomena ** - Comparing different evolutionary theories. For example, Lamarck's use and discard theory and Darwin's theory of natural selection. Lamarck believed that the organs of living things were used or discarded, and that the acquired traits could be passed on to future generations. On the other hand, Darwin's theory of natural selection emphasized that in the struggle for survival, the fittest would survive, and the unfit would be eliminated. Natural selection was the driving force behind biological evolution. Through comparison, one could understand the differences between the two theories and the scientific nature of Darwinian theory. - Comparing the evolutionary characteristics of different biological groups. For example, the evolutionary characteristics of prokaryota and eukaryota were different. Prokaryota had a simple structure and fast reproduction. During the evolution process, they mutated through gene mutation and other methods. Eukaryotes had a complex structure. In addition to gene mutation, there were also ways such as gene reorganization and aberration mutation to increase genetic variation, thus promoting evolution. ** 3. Construct a Knowledge Network of Biological Evolution ** 1. ** Grasp the vertical connection ** - When learning biological evolution knowledge, one had to pay attention to the vertical continuity of the knowledge. For example, starting from the chemical evolution theory of the origin of life, understanding how organic small molecules in the primitive Earth's environment formed organic molecules, then the formation of multi-molecular systems, and finally the formation of primitive life. Then, from the evolution of primitive life to the evolution of prokaryota and eukaryota, and then to the division and evolution of animals and plants. Each stage was developed on the basis of the previous stage. Understanding this vertical connection would help to systematically grasp the entire process of biological evolution. 2. ** Pay attention to horizontal connections ** - The knowledge of biological evolution had a horizontal connection with other biological knowledge. For example, biological evolution was closely related to genetics, and genetic variation was the basis of biological evolution. Gene mutation, gene reorganization, and aberrations provided raw materials for biological evolution, and the change in gene frequency during the process of biological evolution reflected the direction of evolution. At the same time, biological evolution was also related to ecology. In the process of biological evolution, the adaptation of organisms to the environment and the relationship between organisms were the contents of ecological research. Understanding this horizontal connection could broaden the understanding of biological evolution knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
