我国科学家从150年前的沉船里，找到关键信息！

Core Insights - The research team has successfully reconstructed the historical details of a shipwreck from 150 years ago through sediment analysis from a porcelain bottle, revealing insights into the packaging, loading, and sinking environment of the cargo [1][3] Group 1: Research Findings - The sediment analysis from the blue-and-white porcelain bottle indicates a clear stratification at approximately 30 centimeters, with the lower "original layer" containing terrestrial plant DNA and packaging remnants, while the upper "disturbed layer" features marine invertebrate DNA, documenting the ecological colonization process post-sinking [1][3] - The ancient DNA analysis revealed seasonal ecological signals associated with indica rice and insect groups, suggesting that the ship's last voyage likely occurred in summer or early autumn, supporting previous hypotheses that the ship may have sunk due to a typhoon [3] Group 2: Historical Context - The presence of bamboo molecular signals in the original sediment layer corroborates traditional packaging methods, providing clues for reconstructing the packaging techniques used for Qing Dynasty Jingdezhen porcelain [3] - The typological characteristics of the porcelain artifacts indicate their origin from Jingdezhen, Jiangxi, and the DNA signals from the rice packaging materials show a high genetic similarity to local indica rice, suggesting that Jiangxi served as both the production and packaging site for the porcelain [3]
