This year marks 75 years since SSE was founded. To celebrate, we are publishing a special series of Perspectives and Commentaries in Evolution. In January and February we present articles to celebrate SSE’s recent history and impacts [1], and to provide an important assessment of diversity within our field [2]. Over subsequent months, we are publishing articles to highlight key scientists in the field, as well as to celebrate Evolution papers that have had major impacts in the fields of adaptation, coevolution, speciation and macroevolution.  Learn more about the history of SSE here [3] and read the special articles as they come out here [4].
