Features: This book is part of the "Science New Horizons Series from the China Science and Technology Museum." It reviews the history of life sciences, showcases the scientific spirit of truth-seeking, pragmatism, and innovative exploration demonstrated by scientists, popularizes knowledge about genetics and technology, and presents the prospects for the development of life sciences and biotechnology. Every one of us is a living organism, and the food we rely on—grains, vegetables, fruits, meat, eggs, dairy, oils, tea—all comes from other organisms. The Earth we inhabit, which distinguishes itself from any other known planet, is also because it is home to a diverse array of life forms, such as plants and animals. The vibrant and varied manifestations of these life forms are due to the differences in their genetic material and its functions. On April 25, 1953, the double helix structure model of deoxyribonucleic acid (DNA), the genetic material of life, was announced. This was one of the most significant scientific achievements of the 20th century and sparked the subsequent biological revolution. Over the following 50 years, scientists continuously explored the field of genetics and technology, gradually deciphering the mysteries of life's genetic code and mapping the genomes of humans, rice, chickens, and others. They also developed biotechnological innovations such as genetic recombination and cloning. On the basis of these achievements, some scientists predicted that the 21st century would be the century of life sciences. The results of genetics and technology are already and will increasingly influence human production and life, driving economic and social progress. At the same time, they have also sparked debates on issues such as biosecurity, environmental impact, and ethics. On the 50th anniversary of the first publication of the DNA double helix structure model, reviewing the history of life sciences, showcasing the scientific spirit of truth-seeking, pragmatism, and innovative exploration demonstrated by scientists, popularizing knowledge about genetics and technology, and presenting the prospects for the development of life sciences and biotechnology are undoubtedly of great significance for understanding ourselves, nature, and science, and for promoting the coordinated and sustainable development of human society and the natural environment.
