A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
　　The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant,African forest elephant and African savanna elephant
　　Once they obtained DNA sequences (序列) from two fossils (化石),mammoths and mastodons the team compared them with DNA from modern elephants.They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
　　The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years.The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths.This result amazed all the scientists.
　　There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
　　Previously,many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences.麻烦翻译全文.

最近的一项研究古代和现代大象已经拿出了出人意料的结论,非洲象被分成两个不同的物种.
这一发现是由纽约大学和哈佛大学的研究人员在他们所审查的古猛犸象和乳齿象的遗传关系到现代大象,亚洲象,非洲森林象和非洲大草原的大象
一旦他们获得的DNA序列化石 ,猛犸象和乳齿象队相比,他们与现代大象的DNA .他们发现他们惊讶的现代森林和草原的大象是有别于对方,亚洲大象和猛犸象.
科学家使用了详细的基因分析已经证明,非洲稀树草原象和非洲森林象不同的物种,几百万年.两个物种的分歧发生亚洲大象和猛犸象的分歧左右的时间.这个结果感到惊讶了所有的科学家.
长期以来人们一直争论在科学界,这两个可能是独立的物种,但到目前为止,他们确实是不同的物种,这是最有说服力的科学证据.
此前,许多博物学家认为,非洲大草原的大象和非洲森林象的同一物种的两个群体,尽管大象的显着的大小差异.
