现代类人猿与人类的共同祖先是______.______是人类祖先与猿分界的重要标志.

答案

在距今1200多万年前,森林古猿广泛分布于非、亚、欧地区,尤其是非洲的热带丛林,后来由于环境的变化,森林古猿朝两个方面进化,一部分森林古猿仍然以树栖生活为主,慢慢进化成了现代类人猿,如黑猩猩、猩猩、大猩猩、长臂猿等.另一支却由于环境的改变被迫下到地面上来生活,慢慢的进化成了人类,可见人类和类人猿的关系最近,是近亲,它们有共同的原始祖先是森林古猿.

   在人类发展和进化中的重大事件有:直立行走--制造和使用工具--大脑进一步发达--语言的产生.直立行走是进化发展的基础,也是使用工具制造工具的基础.恩格斯曾指出,直立行走是从猿到人转变过程中“具有决定意义的一步”.古猿的直立行走造成了前后肢的分工,直立行走使古人类能够将前肢解放出来,使用工具.前肢所从事的活动越来越多,上肢更加灵巧,直立行走是人猿分界的重要标准.

故答案为:森林古猿;直立行走
