Lake Victoria is the largest lake in Africa and harbors more than 300 endemic species of haplochromine cichlid fish. Seismic reflection profiles and piston cores show that the lake not only was at a low stand but dried up completely during the Late Pleistocene, before 12,400 carbon-14 years before the present. These results imply that the rate of speciation of cichlid fish in this tropical lake has been extremely rapid.
维多利亚湖是非洲最大的湖泊，拥有300多种丽鱼科的特有物种。地震反射剖面和活塞岩芯显示，该湖不仅处于低水位，而且在距今12400年碳-14年代之前的晚更新世就完全干涸了。这些结果表明，这个热带湖泊中丽鱼科鱼类的物种形成速度极快。
