三月的北京,正当绿柳才黄,群芳催动的时候,科学的百花园中绽出一朵奇葩。北京大学生命科学院的一批青年科学家从一枚6500万年前就已灭绝的特殊恐龙蛋化石中获得了恐龙基因片段。这是人类首次从恐龙蛋化石中获得恐龙的遗传物质,它对研究神秘莫测的恐龙及其生存环境,探索物种起源与生物进化的奥秘,具有重大意义。这一新闻,一时间如巨石入水,惊花四溅。喷喷称奇者有之,将信将疑者亦有之,见仁见智,其说不一。 对这一发现是否还需再做科学验证,它在未来的生命科学及人类本身秘密的探讨中究竟意味着什么,我们这些门外汉难以评说。但有一宗,我们着实感到欣慰,这就是:本刊同这批青
In Beijing in March, just as green willow is yellow and Qunfang is driving, a wonderful flower blooms in the science garden. A group of young scientists at the Peking University School of Life Sciences obtained dinosaur gene fragments from a special dinosaur egg fossil that was extinct 65 million years ago. This is the first time that human beings have obtained the dinosaur genetic material from dinosaur egg fossils. It is of great significance to study the mysterious dinosaurs and their living environment, and explore the mysteries of the origin and evolution of species. This news, for a time as a rock into the water, thrilled. Expecting spray spray there, there will be some skeptics, different opinions, its different. Whether this discovery still needs to be scientifically validated is what it means in future life sciences and humanity’s own intimate discussions that we, laymen, find it hard to comment on. But there is one, we really feel pleased that this is: The same magazine with these green
