Hunter-gatherer groups are much less egalitarian than they seem

There is a widespread belief that altruism and equality drive social behaviour in traditional hunter-gatherer societies, but the truth is more surprising and complex

Overall winner Mesmerizing spider threads The image shows two exceptional silk threads of the Australian netcaster spider, Asianopis subrufa. Unlike typical web-builders, this spider holds a specialized, sticky net between its four front legs. When an unsuspecting insect approaches, the spider rapidly expands its net and casts it over the prey, a maneuver that demands dramatic extensibility from the supporting lines at the sides of the sticky net. These threads are composed of an elastomeric core encased in a sheath of harder fibers of varying sizes; the result is a structure that is both strong and stretchy. The mesmerizing, looping fibers in the image capture the eye with their meandering fiber bundles, which shift in their complex winding from large to small scales. The image covers 50 microns in width and was captured using a Zeiss GeminiSEM 360 field-emission scanning electron microscope under high vacuum and after coating of Au-Pd. Minimal adjustments of curves and cropping were applied via Adobe Photoshop. Martin J. Ramirez Museo Argentino de Ciencias Naturales - CONICET
