不但小学生,就连成人也常问起动物的寿命有多久的问题。家畜、家禽的寿命比较容易解答,有关野生动物寿命的资料却很不完全,有些数字还需要科学的考证。因此,不论是专家还是动物爱好者,收集有关动物寿命的资料。无疑具有很高科学价值的。现将我们获得的一些有关动物寿命资料介绍给大家。短促和永恒对于生物学家来说。一滴水就好像一部惊险影片那样引人入胜。当你把眼睛紧贴在显微镜上,就会看到许许多多的小动物在水中游动。这些小动物,是一些单细胞的原生动物,它们是地球上最原始的动物。据研究,原始动物在地球上的出现可以追溯到十亿多年以前。今天,原生动物仍然十分昌盛,在地球上到处都能找到 Not only pupils, but adults, often ask questions about how long the animal's lifespan is. The life span of livestock and poultry is relatively easy to answer. The information on the life expectancy of wildlife is rather incomplete. Some figures still need scientific research. Therefore, whether it be an expert or an animal lover, information on the life of an animal is collected. Undoubtedly has a high scientific value. Now we have some information about the life of animals introduced to everyone. Short and long for biologists. A drop of water is as fascinating as a thriller. When you put your eyes on the microscope, you will see a lot of small animals swimming in the water. These small animals, some single-celled protozoa, are the most primitive animals on earth. According to the study, the appearance of primitive animals on Earth can be traced back to more than one billion years ago. Today, the protozoan is still very prosperous, can be found everywhere on Earth
