Agriculture originated across a broader swath of southwestern Asia’s Fertile Crescent, and over a longer time period, than many scientists have thought, excavations in western Iran suggest.
Between 11,700 and 9,800 years ago, residents of Chogha Golan, a settlement in the foothills of Iran’s Zagros Mountains, went from cultivating wild ancestors of modern crops to growing a form of domesticated wheat called emmer, say archaeobotanist Simone Riehl of the University of Tübingen, Germany, and her colleagues. Until now, most evidence of farming’s origins came from sites 700 to 1,500 kilometers west of Chogha Golan, the scientists report in the July 5Science.
The USA National Phenology Network's Phenology Visualization Tool helps monitor the influence of climate on the phenology of plants, animals, and landscapes in the U.S..
The site allows users to select a plant or animal and view where that species has been reported on a Google Map. It is then possible to view an animation of the species' phenology (phenology refers to recurring plant and animal life cycle stages) through time.
It is also possible to view climate data on the same map. Users can view maximum temperature, minimum temperature and precipitation either by month or annually. If you animate species data through time, with climate visible, you will see the climate data on the background change alongside the phenology data....

Human use of land is a major cause of the global environmental changes that define the Anthropocene. Archaeological and paleoecological evidence confirm that human populations and their use of land transformed ecosystems at sites around the world by the late Pleistocene and historical models indicate this transformation may have reached globally significant levels more than 3000 years ago. Yet these data in themselves remain insufficient to conclusively date the emergence of land use as a global force transforming the biosphere, with plausible dates ranging from the late Pleistocene to AD 1800. Conclusive empirical dating of human transformation of the terrestrial biosphere will require unprecedented levels of investment in sustained interdisciplinary collaboration and the development of a geospatial cyberinfrastructure to collate and integrate the field observations of archaeologists, paleoecologists, paleoenvironmental scientists, environmental historians, geoscientists, geographers and other human and environmental scientists globally from the Pleistocene to the present. Existing field observations may yet prove insufficient in terms of their spatial and temporal coverage, but by assessing these observations within a spatially explicit statistically robust global framework, major observational gaps can be identified, stimulating data gathering in underrepresented regions and time periods. Like the Anthropocene itself, building scientific understanding of the human role in shaping the biosphere requires both sustained effort and leveraging the most powerful social systems and technologies ever developed on this planet -
(Phys.org) —New research shows that to prevent starvation at night, plants perform accurate arithmetic division. The calculation allows them to use up their starch reserves at a constant rate so that they run out almost precisely at dawn.
