THE RESULT

Left: 8000 bp to 10000 bp clusters with Archaic sites from the Arizona Statewide Archaeological Site Database (AzSite http://azsitepublic.asu.edu/) shown in red. More than three-quarters of the sites are in areas identified as eco-tones by the clusters.
Right: 8000 bp to 10000 bp shown in ranges of taxa diversity from <10 taxa (light) to >30 taxa (dark) in five taxa increments. More than three-quarters of all sites are in areas the clusters identify as having more than 10 taxa.
