Evolution of cetaceans decreasing. Other historical climate events can be correlated and matched with the genome history of the Yangtze River dolphin as well. This shows how global and local climate change can drastically affect a genome, leading to changes in fitness, survival, and evolution of a species. The European population of common dolphins ("Delphinus delphis") in the Mediterranean have differentiated into two types: eastern and western.
