周口店北京人遗址位于北京市西南房山区周口店镇龙骨山北部，是世界上材料最丰富、最系统、最有价值的旧石器时代早期的人类遗址。1921年至1927年，考古学家先后三次在“北京人”洞穴遗址外发现三枚人类牙齿化石，1929年，又发现了北京人头盖骨化石，以及人工制作的工具和用火遗迹，遂成为震惊世界的重大考古发现。1930年在周口店遗址还发现距今约2万年前的山顶洞人化石和文化遗物。但随之而来的连年战乱，遗失了自1927年以来发现的全部北京人和山顶洞人的化石标本，迄今下落不明，这一事件成为20世纪考古史上的世界之谜。新中国成立后，恢复了对周口店遗址的发掘研究，获取了大量的宝贵资料，迄今为止，考古学家们已经发掘出代表40多个尸体的头盖骨、下颌骨、牙齿等化石和丰富的石器、骨器、角器与用火遗迹。
北京人洞穴堆积层厚40多米，根据对北京人骨骼化石、石器、用火遗迹等方面的研究，考古学家们认为北京人大约生活在距今70万年到20万年。北京人的脑量平均达到1088毫升，头部特征较原始，但已有明显的现代蒙古人种的特征，男性身高约156厘米，女性身高约144厘米，食物主要来源于狩猎和采集。北京人已经懂得用火和吃熟食，用火主要取于自然，知道保护火种，火的使用完备了人的特征。北京人的发现，为中国古人类及其文化的研究奠定了基础。
北京人的发现，为人类进化理论提供了有利实证，是中国科学家为世界考古史做出的伟大贡献。北京人及其文化的发现与研究，解决了19世纪爪哇人发现以来的关于“直立人”是猿还是人的争论。事实证明，“直立人”是人类历史的最早期，处于从猿到人进化过程最重要的环节，他们是“南猿”的后代，后来“智人”的祖先。北京人具有“直立人”的典型形态标准，而北京人对火的使用，更加完备了其作为人的特征。山顶洞人化石和文化遗物的发现，更充分表明了北京人的发展和延续。北京人的发现，为中国古人类及其文化的研究奠定了基础，是当之无愧的人类远古文化宝库。
