POSTED: Sunday, September 30, 2012, 12:34 PM Peter Andolfatto One of the more difficult aspects of evolution for some people to swallow is the notion that random copying errors in DNA can add up to anything useful.
In two recently published projects, however, scientists show how typos can indeed lead to improvements. In numerous species of insects, they document the DNA errors that led to changes that are not only beneficial but also brilliant. Various species of beetles, aphids, butterflies, and moths have independently acquired genetic errors that allow them to eat highly toxic plants and then use the toxins to defend themselves against predators.
