From everyday life to deep evolutionary time: Anthropocene and contacting temporal scales

New forthcoming talk:

2015, Dec 19 (h.11-13) – III Convegno Nazionale SIAA Società Italiana di Antropologia Applicata, Polo Universitario Città di Prato: From everyday life to deep evolutionary time: Anthropocene and contacting temporal scales (Session “Mitigation, Adaptation, Vulnerability. Analisi di strategie, pratiche e retoriche delle comunità nel contesto dell’Antropocene”). With Enrico Giustiniano Micheli, Elena Bougleux, Nadia Breda et al. Conference Talk. [Ac]

To enable cross-referencing of geologic formations and events from different places on the planet, geologists have subdivided the Earth’s history in periods and eras. Among the concluded periods, the shortest one, Neogene, lasted for more than 20 million years (My), while the longest periods amount to 200+ My. The enormity of these time intervals is hard to imagine, yet necessary to capture and define all the phenomena that are meaningful for the history of such a huge and old system as the Earth. A different logic – the logic of “deep time” and “macroevolution” – is necessary to reflect on a time scale where the history of not only species, but whole Families and Groups, is nothing but the blink of an eye. The current period, Holocene, has started only 11.700 thousand years (Ky) ago, at the end of the last glacial Age, but a serious scientific proposal was advanced to consider that a different period, the Anthropocene, has already taken over from the Holocene. Homo Sapiens as a biological species is 200 to 150 Ky old. The beginning of cognitively modern humans and their diffusion on global scale is even more recent: 80 to 60 Kya (the period traditionally described as the Palaeolithic Revolution or the “great leap forward”). Rhetorically, Anthropocene puts incommensurable time scales in contact with each other, to show the relevance of what humanity has been realizing in historical times, and even of our everyday behaviors and choices. What are the dilemmas, paradoxes, challenges, and implications of this mental operation?

  • Provides a unique multidisciplinary approach to understand macroevolution
  • Presents state of the art scientific methodologies
  • Written by international experts from different fields

This book is divided in two parts, the first of which shows how, beyond paleontology and systematics, macroevolutionary theories apply key insights from ecology and biogeography, developmental biology, biophysics, molecular phylogenetics, and even the sociocultural sciences to explain evolution in deep time. In the second part, the phenomenon of macroevolution is examined with the help of real life-history case studies on the evolution of eukaryotic sex, the formation of anatomical form and body-plans, extinction and speciation events of marine invertebrates, hominin evolution and species conservation ethics.
The book brings together leading experts, who explain pivotal concepts such as Punctuated Equilibria, Stasis, Developmental Constraints, Adaptive Radiations, Habitat Tracking, Turnovers, (Mass) Extinctions, Species Sorting, Major Transitions, Trends, and Hierarchies – key premises that allow macroevolutionary epistemic frameworks to transcend microevolutionary theories that focus on genetic variation, selection, migration and fitness.
Along the way, the contributing authors review ongoing debates and current scientific challenges; detail new and fascinating scientific tools and techniques that allow us to cross the classic borders between disciplines; demonstrate how their theories make it possible to extend the Modern Synthesis; present guidelines on how the macroevolutionary field could be further developed; and provide a rich view of just how it was that life evolved across time and space. In short, this book is a must-read for active scholars and, because the technical aspects are fully explained, it is also accessible for non-specialists.
Understanding evolution requires a solid grasp of above-population phenomena. Species are real biological individuals, and abiotic factors impact the future course of evolution. Beyond observation, when the explanation of macroevolution is the goal, we need both evidence and theory that enable us to explain and interpret how life evolves at the grand scale.
