Late Pleistocene representative sites in North China and their indication of evolutionary human behavior

As in many other regions of the world, the Late Pleistocene in China underwent rhythmic changes of climate, which caused some obvious changes in mammalian fauna, natural landscape and human cultural adaptations. This paper is a brief introduction of four representative Late Pleistocene sites in North China, which are dated at periods between Middle and Upper Palaeolithic, and demonstrated common or particular features from geographic and geological aspects, archaeological and environmental characters, and chronological position. A large transformation happened, reflected by culture remains, showing that environmental changes profoundly influenced human behaviour and inspired new forms of culture appearance. This indicates the clear existence of Middle Palaeolithic at least in North China, which became a foreshadowing for the coming Upper Palaeolithic.
