The reasons for the development and collapse of Maya civilization remain controversial and historical events carved on stone monuments throughout this region provide a remarkable source of data about the rise and fall of these complex polities. Use of these records depends on correlating the Maya and European calendars so that they can be compared with climate and environmental datasets. Correl...
It has been widely acknowledged that self-replicating space-probes (SRPs) could explore the galaxy very quickly relative to the age of the galaxy. An obvious implication is that SRPs produced by extraterrestrial civilizations should have arrived in our solar system millions of years ago, and furthermore, that new probes from an ever-arising supply of civilizations ought to be arriving on a cons...
Environmental determinism is often used to explain past social collapses and predict the future of modern human societies. We assess availability natural resources resulting carrying capacity (a basic concept environmental determinism) through a toy model based on Hurst–Kolmogorov dynamics. also highlight role cohesion, we evaluate it from an entropic viewpoint. Furthermore, make case that, whe...
Civilization collapse scenarios highlight what for some are worrying parallels between past case studies and societies under threat from apparently unprecedented global environmental and climate change today. Archive-based studies of socio-economic responses to climate variability in colonial Mexico suggest that the complex interactions between environment and society influence the degree to wh...
Frederik Dalerum (2014) has nicely summarized what many of us consider the basic question of how conservation biologists should allocate their time in trying to deal with the existential threat to human civilization. How much should we devote to our usual activities—to research that may provide better insights into ways to preserve Earth’s biodiversity, or to promoting local or regional actions...
12 volume 54, number 1 expedition he ancient maya created one of the world’s most brilliant and successful civilizations. But 500 years ago, after the Spaniards “discovered” the Maya, many could not believe that Native Americans had developed cities, writing, art, and other hallmarks of civilization. Consequently, 16th century Europeans readily accepted the myth that the Maya and other indigeno...
C lassic Period Maya society (A.D. ∼250–850) is almost as well known for its collapse as for its tremendous accomplishments in hieroglyphic writing, monumental art, and architecture and an extensive, populous network of cities and towns that crossed the terrain of parts of four modern nations (Mexico, Guatemala, Belize, and Honduras). Indeed, interest in the political and demographic collapse o...
