Answers in Genesis Dawkins interview controversy

In 1998, Answers in Genesis filmed an interview with evolutionary biologist Richard Dawkins. Parts of the interview were included in the creationist film From a Frog to a Prince. The interview was allegedly edited to make Dawkins appear unable to answer an interviewer's question.

The question

The answer
Dawkins has actually answered the creationist question, although it takes much dissecting to figure out exactly what the question means - indeed, Dawkins correctly states that only a creationist would pose a question in that way. The creationists would undoubtedly want a specific, soundbite-like answer, but the reality is a lot more subtle. Not least that if, for example, the gene sequence AGACTT mutated to AGAGTT corresponded to a loss of information, then the equally likely reverse mutation of AGAGTT to AGACTT must correspond to a gain in information. The fuller answer requires some knowledge of information theory, and Shannon information as well as a look in depth at what this means in terms of genetics and biological morphology, with an added layer of complication when you take into account genes that seemingly have no purpose. Natural selection itself acts as a non-random filter of the random array of mutations that happen, contributing to the information content of the gene pool, by reducing prior uncertainty. Dawkins has discussed this in numerous books on evolutionary biology.
