250万年前,人科人属的物种出现在非洲东部的平原上,这些人类的祖先被认为是从人科南方古猿属进化而来。时间又过去50万年,这些远古的人类从非洲扩散开来,在亚洲、欧洲和非洲的各地进化出了多种人属生物,包括鲁道夫人(Homo rudolfensis,约240万至160万年前,东非)、能人(Homo hadoilis,190万至160万年前,东非)、先驱人(Homo antecessor,90万年前,西班牙)、直立人(Homo erectus,170万至30万年前,阿尔及利亚、中国、爪哇)、匠人(Homo ergaster,180万至140万年前,东非、南非、格鲁吉亚)、海德堡人(Homo heidelbergensis,60万至10万年前,欧洲、东非)、尼安德特人(Homo neanderthalensis,Neanderthals,20万至4万年前,中东、欧洲)、克罗马侬人(Homo
About 250 million years ago, human-human species appeared on the plains of eastern Africa, where the ancestors of these humans were thought to have evolved from anthropoids. Over half a million years have passed, these ancient humans have spread from Africa and have evolved a variety of humanoids throughout Asia, Europe and Africa, including Homo rudolfensis (about 2.4 million to 1.6 million years ago) , East Africa), Homo hadoilis (1.9-1.6 million years ago, East Africa), Homo antecessor (900,000 years ago, Spain), Homo erectus (1.7-300 million years ago, Algeria , China, Java), Homo ergaster (1.8-1.4 million years ago, East Africa, South Africa, Georgia), Homo heidelbergensis (600,000-1000 years ago, Europe, East Africa), Neanderthal (Homo neanderthalensis, Neanderthals, 200,000 to 40,000 years ago, the Middle East, Europe), Homo
