By Greta Noble 25,000 blue whales swim throughout the oceans every day. 300 million humans walk through the streets of the United States every day. 1.8 million Americans will be diagnosed with cancer this year. None of the blue whales swimming through the oceans have this chronic illness. While it would seem that the increase in cell count of large animals would correlate to an increase in the quantity of cancer cells, it turns out that blue whales do not get cancer. This puzzle is known as Peto’s Paradox. As scientists conduct more research, they believe that large, long-lived animals seem to have evolved mechanisms that are 1000 times more capable of suppressing cancer than humans. Through genomics and comparative methods, scientists are working to understand and utilize these suppressors for treatment in human cancer therapy. For example, genomic analyses revealed that the African elephant genome contains 20 copies of t...
