Climate models and paleoclimate proxy records indicate that the absence of preserved eastern Mediterranean organic-rich layers preceding mid-Pliocene glaciation is linked to a pan-North African humid period caused by a more northerly African monsoon front relative to subsequent glacials. The vegetation expansion caused by this humid phase might have influenced early hominin dispersal.

温暖的上新世期间延长的泛北非湿润期


气候模型和古气候代理记录表明，上新世中期冰川期之前缺乏保存完好的东地中海有机丰富层与泛北非湿润期有关，该湿润期是由相对于随后的冰川期更偏北的非洲季风锋引起的。这个潮湿阶段引起的植被扩张可能影响了早期古人类的扩散。
