Having confirmed that Malagasy and Indonesian DNA separated about 1,200 years ago,which is statistically close to the date archaeologists suggest Madagascar was colonised, theteam then asked their data how many women, drawn at random from the Malay Archipelagoof that period, would have been needed to explain the variation in mitochondrial DNA inMadagascar. The answer was about 30.
由于已确定马达加斯加人和印尼人的DNA是在约1200年前分开的这与考古学家们统计得出的马达加斯加成为殖民地的时间相近,接着Cox博士带领的小组就开始对随机抽取的那一时期的数据进行女性人数的解析,看需要达到多少人才可以解释线粒体DNA在马达加斯加岛产生的变异情况。最后得出的女性人数为30人。
That answer bears on a second question: was the colonisation of Madagascar a deliberateact or an accident? The first is possible. At the time, much of the Malay Archipelago was in thehands of the Srivijayan empire, an entity that could certainly have sent expeditions acrossthe Indian Ocean, had it so willed. But there is no historical evidence that it did. In any caseif it had, it is likely that a successful colonisation by one group would have been followed byothers, as happened when Europeans discovered the Americas.
由此又产生了第二个疑问:在马达加斯加进行的殖民活动是蓄意而为还是偶然而为?前者是有可能的。那一时期,马来群岛中的大多数岛屿都被一个名为Srivijayan的帝国所掌控。该帝国只要愿意,就完全有可能派出远征队穿越印度洋。但还没有史学依据证明他们派出了远征队。不管怎样,如果他们真的这么做了,那么第一批人殖民成功,就会有其他人紧随其后,正如欧洲人发现了美洲大陆后的情况一样。
