Link between marine algae and whale diversity over last 30 million years, study finds

ScienceDaily (2010-02-22) -- New research shows a strong link between the diversity of organisms at the bottom of the food chain and the diversity of mammals at the top. Throughout the last 30 million years, changes in the diversity of whale species living at any given time period correlates with the evolution and diversification of diatoms, tiny, abundant algae that live in the ocean.
