可可树贸易繁荣至少5000年
据国际最新研究，可可树（Theobroma cacao）或至少在5000年前就通过贸易路线从亚马孙盆地传播到了中南美洲的其他地区。
这一发现基于对古代容器的残留物进行分析。研究人员在哥伦比亚、厄瓜多尔和秘鲁的考古遗址中发现了可可残留物，这些遗址可以追溯到公元前3000年至公元前1500年。
研究表明，可可树在中南美洲的传播与早期人类贸易网络的发展密切相关。可可豆被用作货币、饮料和食品，因此成为重要的贸易商品。
研究人员表示，这一发现有助于我们了解古代中南美洲的贸易模式和文化交流。它还表明，可可树在该地区有着悠久的历史，其重要性可以追溯到数千年前。
这项研究由来自美国、哥伦比亚和秘鲁的科学家共同完成，发表在《科学报告》杂志上。研究人员认为，他们的发现将有助于进一步研究古代中南美洲的贸易和文化互动。

**Body:**
Cacao trade flourished atleast 5,000 years ago, with the Theobroma cacao tree spreading from the Amazon Basin to other parts of Central and South America via trade routes, according to new international research.
The discovery is based on the analysis of residues from ancient vessels. Researchers found cacao residue in archaeological sites in Colombia,Ecuador, and Peru, dating back to 3000-1500 BC.
The study suggests that the spread of cacao across Central and South America was closely linked to the development of early human trade networks. Cacao beans were used as currency, a beverage, and food, making them a valuable trade commodity.
The findings help us understand trade patterns and cultural exchange in ancient Central and South America, researchers say. They also indicate that cacao has a long history in the region, with its importance dating back thousands of years.
The research was conducted by scientists from the United States, Colombia, and Peru and published inthe journal Scientific Reports. The researchers say their findings will help inform further research into ancient Central and South American trade and cultural interactions.
