In 1925, the French Jesuit geologist, paleontologist, and theologian Pierre Teilhard de Chardin was removed from his teaching position at the Institut Catholique in Paris. He spent most of the next twenty years in China and his major theological writings were not published during his lifetime. We have uncovered major new archival sources on the investigation of Teilhard by the Jesuit curia and the Holy Office of the Roman Catholic Church. These include the Six Propositions to which he was required (...) to subscribe, which are here published and analyzed for the first time, along with his subscription. Associated correspondence, including a letter written by Teilhard to the Jesuit superior general Wlodimir Ledóchowski, enables a fuller understanding of Teilhard's response to the investigation of him. Moreover, comparison with similar investigations into other theologians in the first half of the 1920s allows an assessment of how the complex power dynamics between the Jesuit curia, the Holy Office, and Pope Pius XI shaped the outcome.

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.
