Penguin DNA
Description
Generation after generation of Adelie penguins have nested in the same Antarctic location for thousands of years. Researchers in Brisbane are comparing old DNA from penguin fossils and DNA from more recent samples to measure the rate of evolutionary change. On his last trip to Antarctica, Paul Willis gathered a few feet from deceased Adelie penguins at Brown Bluff, on the tip of the Antarctic Peninsula. The analysis of the DNA is helping to build a picture of evolutionary change that is much faster than previously estimated.
