Archaeological evidence indicates that ancient Egypt and Mesopotamia may have been in contact at least 10,000 years ago, when people in Mesopotamia began to farm and domesticate animals, and so making the transition from hunter-gatherers to an agricultural society. Many scholars believe that this social and technological revolution may have influenced similar developments in ancient Egypt, but there's been no irrefutable proof of direct contact between the populations until now.考古证据表明，古埃及文明和美索不达米亚文明可能早在一万年前就有过接触。当时，美索不达米亚人开始进行农垦并驯化动物，从而开启了从狩猎采集者向农耕社会的转变。许多学者相信，这一社会和技术变革可能影响了古埃及文明的类似发展进程，但此前还没有确凿的证据证明两个人群之间发生过直接接触。

Scientists have been using ancient DNA analysis to track changes in human evolution over millions of years, but refinements of the technique mean the technology now has the potential to show more recent historical events in a new way.科学家一直在用对人类远古 DNA 的分析来追踪人类在数百万年间的进化过程，但这项技术的改进意味着它现在有可能以一种新的方式呈现更近期的历史事件。
