This is an excellent conference full of science and critical thinking lectures and panels. My podcast, the SGU, will be recording a live show on stage Saturday. I will also be running two 1-hour workshops on critical thinking on Friday. I will be moderating a panel debate on GMO which should be very exciting. Planet of the Apes. 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. Why Evolution Is True.
