对人类起源问题,人们众说纷纭。考古学认为,人类起源至今已有300万年,但美国学者根据基因排序的结果推算,人类起源到现在只有14万年。另外,由于人类同时具有陆生和水生两类动物的特征,因此对人类究竞产生于陆生动物还是水生动物也争论不休。根据人类与其他动物的相似程度,人类应当是地球生物长期演化的结果,而绝不是天外来客。笔者认为,人类是由陆生动物感染了携带水生动物基因 There are different opinions about the origin of human beings. Archeology believes that human origin has been 3 million years ago, but American scholars have calculated according to the results of genetic sequencing that human origin has only been 140,000 years. In addition, because humans also have the characteristics of both terrestrial and aquatic animals, debates have arisen about whether humans produce terrestrial animals or aquatic animals. According to the degree of similarity between humans and other animals, human beings should be the result of long-term evolution of the earth’s biology, and are by no means extraterrestrial visitors. The author believes that humans are infected by terrestrial animals carrying aquatic genes
