Was Michael Behe Right?
An very interesting study has now made the press cycle. Susanne Dobler and Anurag Agrawal studied the genetic mechanism employed by monarch butterflies to resist cardenolides, a powerful toxin which binds the cell’s sodium pump, and which is common to milkweed and foxgloves. They found that a single ” specific mutation — called N122H — of the Na,K-ATPase gene” was enough to confer resistance. They then looked in other insect lines to see what genetic mechanism was employed by these other lines. “Already knowing how monarchs deal with the toxin, we wanted to see if it was the same molecular solution used by beetles, flies and true bugs that are also resistant to cardenolides,” said Anurag Agrawal, a Cornell professor Read More ›
