DNA in the bones of Adelie penguins that survived the last ice age are helping to shed light on how other animals will cope with climate change, say researchers.Evolutionary biologist Professor David Lambert of Griffith University in Brisbane and colleagues report their analysis of Adelie penguin DNA dating back to 37,000 years in the journal PLoS Genetics.

"Adelie penguins are a wonderful model to study the problem of climate change," said Lambert. "They have lived through temperature fluctuations much higher than those in equatorial regions."Lambert said Adelie penguins have survived several degrees of warming since the last glacial maximum 18,000 years ago.
