Every year SSE celebrates Darwin’s birthday (February 12th) with the Darwin Day Roadshow [1], an SSE and BEACON [2] program to bring hands-on science activities to K–12 students. This year we also engaged with other scientists and the public on social media to celebrate the diversity of researchers, questions, approaches and study organisms in our community—the breadth and depth of which Darwin never could have imagined. Thank you to everyone who joined the conversation on Twitter! Search the hashtag #IStudyEvolution to see the great variety of exciting research happening in this field.
