Abstract
We describe the content and outcomes of the First Workshop on Open-Ended Evolution: Recent Progress and Future Milestones (OEE1), held during the ECAL 2015 conference at the University of York, UK, in July 2015. We briefly summarize the content of the workshop's talks, and identify the main themes that emerged from the open discussions. Two important conclusions from the discussions are: (1) the idea of pluralism about OEE-it seems clear that there is more than one interesting and important kind of OEE; and (2) the importance of distinguishing observable behavioral hallmarks of systems undergoing OEE from hypothesized underlying mechanisms that explain why a system exhibits those hallmarks. We summarize the different hallmarks and mechanisms discussed during the workshop, and list the specific systems that were highlighted with respect to particular hallmarks and mechanisms. We conclude by identifying some of the most important open research questions about OEE that are apparent in light of the discussions. The York workshop provides a foundation for a follow-up OEE2 workshop taking place at the ALIFE XV conference in Cancún, Mexico, in July 2016. Additional materials from the York workshop, including talk abstracts, presentation slides, and videos of each talk, are available at http://alife.org/ws/oee1 .
Highlights
From the first experiments with digital evolution in the 1950s to the increasingly sophisticated simulations of the present day, the concept of open-ended evolution (OEE) has been a central concern for artificial life (ALife) researchers [51]

A follow-up workshop (OEE2) will take place at the ALIFE XV conference in Cancún, Mexico in July 2016.3 The Cancún workshop will be followed by a special issue on open-ended evolution in the Artificial Life journal, including a comprehensive review paper on work on OEE
Summary
From the first experiments with digital evolution in the 1950s to the increasingly sophisticated simulations of the present day, the concept of open-ended evolution (OEE) has been a central concern for artificial life (ALife) researchers [51]. To take stock of and document recent work, and to identify key milestones for the immediate future, a workshop on Open-Ended Evolution: Recent Progress and Future Milestones (OEE1) was held at the European Conference on Artificial Life (ECAL 2015) at the University of York, UK, in July 2015.2 The workshop aimed to create a common framework for discussing and evaluating research on open-ended evolution, and to catalyze further progress. The second session was an open discussion among the speakers and other attendees about openended evolution, focusing on the key hallmarks of various kinds of OEE and the hypothetical mechanisms that could produce those hallmarks.
