Probable Evidences of Recent Biological Activity on Mars: Appearance and Growing of Dark Dune Spots in the South Polar Region
Abstract
We imply from MGS images' morphological analysis: Dark Dune Spots (DDSs) on sand sheets, S. polar reg. Mars: 1) DDSs do not fit to fine topography, 2) water flows out from DDSs, 3) sublimation + recent biological activity explain their changes.
