<font size="4">The importance of deleterious mutations in adaptive evolutionWilke lab goes social media</font>
<font size="2"> Posted on 08/0818/2013 </font>
One might think Last week, nearly the entire lab attended the [ BEACON] Congress, where Titus Brown gave a persuasive talk arguing that deleterious mutations will always be disadvantageous in adaptive evolution. [ scientists should get more involved with social media.1073/pnas] In response, we decided to be more active with social media as well.1313424110 Yet in First, we made a study published in PNAS this week,] UT Research Educator and Wilke-lab member [ Art Covertauthors/Claus%20Wilke/447154 figshare account] shows that populations experiencing deleterious mutations can often do better, in for the lab and posted several of the posters and slides we presented at the long runBEACON Congress. Second, than comparable populations in which deleterious mutations have been disabledwe [https://twitter. This seemingly paradoxical result arises because deleterious mutations can serve as stepping stones in adaptive evolution: sometimes, higher fitness peaks are inaccessible to populations unless com/ClausWilke tweeted] about the populations first take a step down into a fitness valleymaterials we posted on figshare.  This paper was co-authored with Richard Lenski (MSU)Third, Claus Wilke (UT Austin)decided to [ start a blog, and Charles Ofria (MSU)] where he will post his personal opinions on scientific as well as non-scientific topics.
