Freshwater herring had salty origin

East Africa’s Lake Tanganyika has a highly diverse fauna which closely resembles marine animals. A researcher at the University of Zurich has traced the origins of the freshwater herring of the Lake to a marine invasion which occurred in West Africa 25 to 50 million years ago, coincident with a major oceanic incursion into the region. The ancient freshwater capture of marine organisms may help to explain the origins of other species unique to this Lake. The findings are published this week in the journal PLoS ONE.
