The origin of silk can be traced back to the Neoliths 5000 years ago. Legend has it that when the wife of the Yellow Emperor, Leizu, married the Yellow Emperor from Xiling (now Xiping, Henan Province), she brought the technique of raising silkworms with her. In 1926, half a silkworm cocoon was discovered in the excavation of the Yangshao cultural site in Xiyin Village, Xia County, Shanxi Province (about 3500 B.C.). In 1956, a bamboo basket containing silk sheets, silk threads and ribbons was discovered in the Qianshanyang site in Huzhou, Zhejiang Province (4200 years ago). In 1983, a plain fabric woven with silk threads was excavated in the Neoliths site in Qingtai Village, Xingyang City, Henan Province, about 5500 years ago. These archaeological discoveries also proved the long history of silk. In terms of the types of silk, the types of ancient silk fabrics included silk, yarn, Qi, damask, Luo, brocade, satin, and silk. Today, according to the structure, craftsmanship, appearance, and use, it was divided into 14 categories: yarn, Luo, damask, silk, spinning, gauze, crepe, brocade, satin, tizu, ge, woolen, velvet, and silk. Different types of silk had their own characteristics and uses in different historical periods. For example, damask was still popular after the Tang Dynasty, and was mostly used to mount paintings and calligraphy in the Ming and Qing Dynasties. Luo appeared in the Shang Dynasty. Yue Luo in Zhejiang and Single-Silk Luo in Sichuan were famous in the Tang Dynasty. Luo, which was light and transparent in the Song Dynasty, became the new favorite in the market.

The Origin of Species was written by the British biologist Charles Robert Darwin. It was a biology book that systematically elaborated on the basic theory of biological evolution. The full name was On the Origin of Species through Natural Selection, or the Preservation of Superior Groups in the Struggle for Survival. He began his work in 1842, after a five-year expedition (1831 - 1836) with the Beagle. However, because he felt that the evidence for evolutionary theory was insufficient, he did not finish writing and publishing it. In the summer of 1858, he received a letter from Alfred Russell Wallace explaining the principles of evolution and natural selection. However, under the coordination of Charles Lyell and Joseph Dalton Hooke, some of the manuscripts and letters of Darwin's theory of natural selection and Wallace's paper were read at the Linnean Society on July 1, 1858 and published in the Linnean Society. After that, Darwin worked hard on his writing and greatly reduced the content of his original plan. After more than 13 months of intense writing, he published the book in London, England, on November 24, 1859. The core idea of Origin of Species was natural selection, and its core mechanism was the struggle for survival. Darwin also proposed the theory of trait disagreement, which believed that different species might have the same ancestor. The book was divided into three parts. First, it presented the theory of evolution, then explained the difficulties from the opposite side, and finally, it provided evidence for the theory with the combination of geological and other disciplines. Although the book was controversial when it was published, it was still widely circulated. It has now been translated into more than 30 languages and is widely read and debated around the world. Its publication marked the official establishment of Darwin's theory of evolution and was the basis of modern evolution. The theory of natural selection in Darwin's theory of evolution also provided the basis for many later theories. "The Island of Life" is also a wonderful novel. Everyone is welcome to read it!
