The evolving content of <i>BioScience</i>

The evolving content of BioScienceWe are pleased to introduce a new submission category, Key Challenges, articles that summarize the important challenges and questions that need to be addressed.We especially seek submissions that prioritize unaddressed challenges or questions for a field.The first to be published in BioScience is "Evolvability: Progress and key questions" ( https://doi.org/10.1093/biosci/biaf111), written by Plabon and colleagues (with an initial push by W. Scott Armbruster).They focus on the ability of biological systems to evolve and how this ability itself can evolve.What especially struck me about their article is the demonstration of the finetoothed comb of natural selection, which can nonrandomly sift through complex genetic phenomena to favor even the evolution of the basic parameters of the evolutionary process.Our Overview article, simply titled, but discussing a phenomenon of enormous consequence, is "The role of fire on Earth" ( https://doi.org/10.1093/biosci/biaf132 ) by Pausas and colleagues.They discuss the profound ways that fires shapes the Earth's landscape and how "to understand and predict the role of fire in a densely populated, highly technological world that imposes significant changes on the Earth."In addition, we have three synthesis articles, Forum contributions, having important implications for conservation policy.Our first is by Mateo-Toms and colleagues, "Leveraging animal tracking to combat wildlife crime: GPS-tagged vultures and wolves as sentinels of other species' poaching" ( https://doi.org/10.1093/biosci/biaf136).In this article, the authors make the obvious observation that since scavengers are naturally selected to detect dead animals, following scavengers through GPS technologies can lead to the early detection of poached, illegally harvested animals.Our second Forum article, by Boerigter and colleagues, "Guardians and gardeners: Managing wilderness for the twenty-first century" ( https://doi.org/10 .1093/biosci/biaf141 ) "consider[s] how a guardians and gardeners approach would acknowledge Indigenous influence, recognize contemporary and future environmental challenges, and provide
