Core Viewpoint - The research team from China University of Geosciences (Wuhan) and the California Academy of Sciences has developed an innovative ancient ecological simulation methodology that reconstructs ancient food webs from fossil records, expanding the research paradigm in paleobiology [1][2]. Group 1: Research Methodology - The newly established ancient ecological simulation method connects fragmented fossil records into a coherent ancient food web, allowing for a more systematic and macro-level study of ancient ecosystems [1]. - The core of this simulation method lies in deciphering the evolution of ancient ecological structures, addressing challenges in reconstructing ancient food webs and quantitatively assessing ancient community dynamics [1]. Group 2: Applications and Implications - This simulation method is broadly applicable across various ecosystems, both terrestrial and marine, facilitating the transition of paleobiology from qualitative descriptions of single species to quantitative studies of ecosystems [2]. - The research holds significant implications for modern Earth, as it seeks to extract "historical wisdom" from geological records to address contemporary ecological crises, with each instance of ecological collapse and recovery serving as a survival guide for humanity [2].
