Peking man, extinct hominin of the species Homo erectus, known from fossils found at Zhoukoudian near Beijing. They lived between 750,000 and 200,000 years ago. Homo heidelbergensis is an extinct species or subspecies of archaic humans in the genus Homo, which radiated in the Middle Pleistocene from about 700,000 to 300,000 years ago. Neanderthals are an extinct species or subspecies of archaic humans in the genus Homo, who lived within Eurasia from circa 400,000 until 40,000 years ago. Cro-Magnons had powerful bodies, which were usually heavy and solid with strong muscles. Unlike Neanderthals, which had slanted foreheads, the Cro-Magnons had straight foreheads, like modern humans. They lived 400,000 to 37,000 years ago. Hence Peking man→ Heidelberg man→ Neanderthal man→ Cro-Magnon man is the correct order in the evolutionary history of man. So, the correct answer is 'Peking man→ Heidelberg man→ Neanderthal man→ Cro-Magnon man'.
