Scott Van Keuren Analyzed Brushwork Sequences in Decorative Styles of the Pottery

Scott Van Keuren analyzed brushwork sequences in decorative styles of the pottery of the Southwestern United States. His research found that changes in style could be explained as evidence that

A) societies with different original styles had moved to the same area leading to styles derived from several original styles
B) the presence of similar pottery designs in the Four Corners and along the Little Colorado River in Arizona demonstrated that the former had driven out the latter groups
C) the consistency of religious iconography found on Fourmile pottery demonstrated that although the people had moved from the Four Corners region, their social patterns, including pottery styles and designs, remained stable and unchanged
D) all of the above.
