开栏语时至今日,在人类探测能力所及的范围内,除了地球还未发现别处有什么生命迹象。因此,无论怎么看,生命都是很奇特的,非常奇特!也是很珍贵的,极其珍贵!美丽的双螺旋结构的DNA,按照设计发挥功能的蛋白质——因为这两种物质,细胞便能无差错地复制自身,留下子孙,在地球上形成了各种各样生生不息的美丽生命!对生命了解得越多,我们就越会感到它们的神奇、复杂、美丽和珍贵,也就越发地会去珍爱生命!通常,生命世界被划分为五个界:动物界,原核生物界,原生生物界,真菌界和植物界。据科学家估计,地球上的生命种类应该在500万到1000万种之间。目前,人类已发现的有175万多种,其中有超过100多万种生活在陆地上。而动物界无疑是生命界中最大最繁多最聪明的种类。我们知道,所有的生命都是由极其相同的物质组成的,构成生命的原子物质与构成地球上的高山、海洋以及银河系、宇宙中所有星辰的物质完全相同。可生命却为什么如此特别,如此充满了智慧呢?它们最初是如何形成,怎样发展进化,而到了今天各自又都是什么样子的呢?有关生命特别是动物的问题有许多许多,而这些也正是小读者们很感兴趣的话题和科普知识。为此,本刊特开辟了“生灵之舞”这个新栏目,以求能为大家介绍一二。
In the context of human detection capabilities today, no sign of life has been found anywhere else on the planet. So, no matter how you look, life is very strange, very strange! Also precious, extremely precious! Beautiful double helix DNA, designed to function as a protein - because of these two substances, Mistakes are duplicating itself, leaving children and grandchildren, and forming a great variety of life on Earth. The more we know about life, the more we feel it’s magic, complexity, beauty and preciousness. The earth will go to cherish life! Usually, the world of life is divided into five circles: animal kingdom, prokaryote kingdom, protist kingdom, fungal kingdom and plant kingdom. Scientists estimate that the type of life on earth should be between 5 and 10 million. Currently, more than 1.75 million species have been discovered by mankind, of which more than a million live on land. The animal world is undoubtedly the largest, most numerous and the smartest species in the life world. We know that all life is made up of very same things. The atomic matter that constitutes life is exactly the same as the matter that makes up all the stars in the universe that make up the earth’s mountains, oceans and the Milky Way. Why is life so special, so full of wisdom? How did they form at first, and how did they evolve? And what are they like today? There are many problems concerning life, especially animals, and these are also Is a topic that is of interest to young readers and science knowledge. To this end, the article has opened up a “dance of the living” this new section, in order to be able to introduce one or two for everyone.
