This workbook allows students to explore evolution over space and time using published data on the invasive plant Tamarix (salt cedar). The program plots the geographic location of samples representing Tamarix haplotypes of the user's choice, as well as calculating statistics that describe the samples' geographic distribution. Finally, GeoPhyl conducts a permutation test that allows the user to determine, both graphically and numerically, how well the observed data match a random geographic distribution. Note that this file requires that "macros" are enabled in Microsoft Excel.
