The lengths separating nearest neighbors in three populations of FJ7 macrofiber aggregate forms. All nearest neighbor links were drawn manually on images from populations 97–142, 916–444, and 920–400, and the length of each link was determined using a computer graphics program. The lengths were then ordered from shortest to longest within each population and plotted as a function of length. Arrows indicate the mean link length in each population. See Table 2 for further details.
