Biological evolutionary insights into the origins of agriculture: Evidence from the origin of rice agriculture

Abstract The domestication of plants and animals was a unique evolutionary process influenced by human behavior. In the early stage of domestication, the morphological and genetic characteristics of plants and animals still exhibited wild traits, making the concept of the “earliest” crops and domestic animals relative. Human behavior, acting as an unconscious selection mechanism, influenced the process and rate of domestication, making it a crucial factor in identifying domestication. Archaeological evidence of early cultivation and a sedentary lifestyle indicates that the domestication of rice and the origin of rice agriculture in China spanned four to five thousand years, with significant advancements occurring approximately every two thousand years. The origin of rice agriculture began around 10,000 years ago, entered a critical stage around 8000 years ago, and was completed around 6000 years ago. After this period, farming replaced gathering and hunting as the core of the subsistence economy, leading to the establishment of agricultural societies where agricultural production became the driving economic force.
