　　据和记百科网站「北海的猫」消息，近日，关于地球的标志！人类在地球上出现的标志是「分享」引发热议，关于地球的标志同样引起许多争议，对此众网友各抒己见。但到底是怎么回事呢？和记百科为您解答。

人类在地球上出现的标志是

　　人类在地球上出现的标志是直立行走。古猿的直立行走造成了前后肢的分工，使古人类能够将前肢解放出来，能使用工具。前肢所从事的活动越来越多，上肢更加灵巧，古猿便慢慢的进化成了人类，因此人类在地球上出现的主要标志是直立行走。直立行走是进化发展的基础，是人类脱离森林束缚，是使用工具、制造工具的基础。

　　人类的历史发展：

　　直立人如何进化到智人大致有两种学说。一种为多区域连续学说，认为直立人从非洲迁移到亚欧大陆，然后欧、亚、非三地的直立人分别进化为各地的智人，由于进化过程中异地的人持续发生杂交，所以仍保持同一基因库，属于同一人种；另一学说为非洲起源学说，认为人类进化过程中发生过两次大迁移，一次是直立人的迁移，另一次则是非洲的直立人进化为智人，然后又迁移到亚欧大陆，这次迁移大约发生在10万年前。而智人可能在150万~30万年前就已出现。这两种学说都还没有可靠的依据，人类起源问题的最终解决仍有待于更多的工作。

关于地球的标志

　　一个地球一个马的雕塑是中国优秀旅游城市标志。该雕塑从外观上看，最上面是马踏飞燕，下面是一个地球，底座是长城烽火台。

　　在中国很多优秀旅游城市，都有这样的标志性雕塑，事实上这是中国优秀旅游城市标志。以长城烽火台为底座，一匹骏马踏着地球向前奔腾翻滚。

　　【英文介绍/For English】：

　　The hallmark of human presence on Earth is walking upright. The upright walking of ancient apes caused the division of labor between the front and rear limbs, which enabled ancient humans to liberate their forelimbs and use tools. The forelimbs engaged in more and more activities, and the upper limbs became more dexterous, and the ancient apes slowly evolved into humans. Therefore, the main symbol of human beings on the earth was walking upright. Walking upright is the basis of evolution and development, it is the basis for human beings to break free from the shackles of forests, and the basis for using tools and making tools.

　　The historical development of human beings:

　　There are roughly two theories on how Homo erectus evolved to Homo sapiens. One is a multi-regional continuum theory, which holds that Homo erectus migrated from Africa to the Eurasian continent, and then Homo erectus in Europe, Asia, and Africa evolved into Homo sapiens in various places. It still maintains the same gene pool and belongs to the same species; the other theory is the African origin theory, which holds that two major migrations occurred during human evolution, one was the migration of Homo erectus, and the other was the evolution of Homo erectus from Africa to Homo sapiens , and then migrated to Eurasia, this time around 100,000 years ago. Homo sapiens may have appeared between 1.5 million and 300,000 years ago. There is no reliable basis for either of these theories, and more work remains to be done to finally resolve the question of human origin.
