The graduation photo of An Yongrui, a paleobiology major at Peking University, has become an internet sensation after he recently posted it online.近日，北京大学古生物学专业毕业生安永睿在将自己的毕业照发布到网上之后，迅速走红。Unlike other college graduates, An posed for his graduation photo alone, as he is the only paleobiology graduate this year at the prestigious university's Yuanpei School.与其他大学毕业生不同的是，安永睿发布的毕业照中只有他一个人，因为他是今年这所名校的元培学院该专业唯一的毕业生。An Yonghuiis the "sixth generation" of alumni carrying the legacy of paleobiology, since the major was introduced in 2008.据报道，安永睿是自2008年古生物学专业设立以来的"第六代"毕业生。Before him, there were a total of five alumni who majored in paleobiology - in each previous year there was only one graduate, as few college students choose it as a major.在他之前，该专业共有5位毕业生。由于选择古生物学专业的学生极少，此前每年都只有一个毕业生。

Paleobiology is a science discipline that combines biology and geology to study the history of life on Earth through fossils. According to a previous report, the school may be the only one in the country to enroll a single undergraduate student annually for a course of study - not from lack of trying but because few are interested in paleontology.古生物学是一门结合了生物学和地质学，通过化石来研究地球上生命的历史的科学学科。根据以前的一项报告显示，该校可能是唯一一个在全国每年招收一个本科学生的学校。这并不是因为缺乏尝试，而是因为很少有对古生物学感兴趣的学生。The highly specialized field was under the limelight in 2014 after that year's paleobiology graduate, Xue Yifan, posted a photo of only herself standing in front of a building in the campus, captioned "Paleontology Class 2014, Peking University". The photo soon circulated online and triggered a flurry of discussion.这一高度专业化的领域是在2014年出现在聚光灯下的。当年该专业毕业生薛逸凡发布了一张只有她自己站在校园建筑物前、标题为“北京大学2014级古生物学专业”的照片。这张照片很快在网上流传开来，引发了一系列的讨论。Xue has now completed her master's program in computational biology at Carnegie Mellon University in Pennsylvania and is looking forward to working on her PhD at the University of Pittsburgh.薛逸凡现在已经完成了美国宾夕法尼亚州卡内基梅陇大学计算生物学硕士课程，正在准备攻读匹兹堡大学的博士学位。For An Yonghui, the reason he chose the major is almost the same as Xue Yifan's - his great interest in paleobiology.对于安永睿来说，选择该专业的原因几乎和薛逸凡完全一样，那就是自己对古生物学有着极大的兴趣。
