Evolution in an Egg Shell

Massey University’s David Lambert has published his findings on the microevolution of Antarctica’s Adélie penguins in the Proceedings of the National Academy of Sciences. Lambert’s research shows a marked difference between the genetic make up of modern day Adélie penguins and their 6,000 year old ancestors. He believes this was caused by the splitting up of giant icebergs in Antarctica, which forced many nesting colonies to migrate and interbreed with other types of penguins.
