奋蹄前行！从我国科研视角看马的演化传奇

Core Viewpoint - The evolution of horses, particularly the three-toed horse and the Przewalski's horse, reflects resilience and adaptability in the face of environmental changes, highlighting the importance of biodiversity conservation in China [2][3][6]. Group 1: Three-Toed Horse Evolution - The three-toed horse has shown remarkable species diversity and adaptability through cross-continental migration over millions of years, with significant fossil evidence found in China [2]. - Key discoveries from the Chinese Academy of Sciences have clarified the evolutionary history of the three-toed horse, including its arrival in East Asia 11.5 million years ago [2]. - Research indicates that the three-toed horse adapted to various environments, demonstrating strong environmental adaptability, particularly in arid Asian regions and moist European forests [2]. Group 2: Przewalski's Horse Conservation - Przewalski's horse, the only remaining wild horse species, has a 60 million-year evolutionary history and is closely related to domestic horses [3]. - Due to overhunting, Przewalski's horse became extinct in the wild by 1969, with current populations being descendants of a few remaining individuals [3]. - China initiated a long-term "Return of the Wild Horse" program in 1985, leading to successful breeding and rewilding efforts, with the population exceeding 900 individuals by the end of 2025 [4][3]. Group 3: Broader Implications - The stories of the three-toed horse and Przewalski's horse symbolize resilience and the importance of biodiversity conservation, resonating with contemporary themes of ecological protection in China [6]. - The cultural significance of horses in Chinese society reflects values of strength and perseverance, aligning with national efforts in scientific exploration and ecological conservation [6].
