800,000 年前的 AMY1 基因复制与人类早期对淀粉类饮食的适应有关。 800,000-year-old AMY1 gene duplication linked to early human adaptation to starchy diets.

水牛大学和杰克逊实验室的一项研究表明,对于消化淀粉至关重要的盐碱氨基酶基因(AMY1),早在农业开始之前80多万年前就已经重复了。 A study by the University at Buffalo and Jackson Laboratory reveals that the salivary amylase gene (AMY1), crucial for digesting starch, may have duplicated over 800,000 years ago—long before agriculture began. 这种基因变化使得早期人类及其祖先,包括尼安德特人,能够适应含粉的饮食. This genetic change allowed early humans and their ancestors, including Neanderthals, to adapt to starchy diets. 农业前狩猎采集者拥有多份AMY1副本,表明对碳水化合物丰富食品的早期适应。 Pre-agricultural hunter-gatherers had multiple AMY1 copies, indicating an early adaptation to carbohydrate-rich foods.
