Fig. 10. Average IQV for twenty squares and fifty-eight holes by time period. Variation in fifty-eight holes boards also began high, but never witnessed a period of winnowing. Instead, variation in board form remained high compared to twenty squares and, if anything, seems to have decreased slightly over time. This is not consistent with our hypothesis. As shown in Table 4, the innovation frequency was higher than twenty squares, but a larger fraction of the innovations that appeared were not retained in the larger pool (i.e., appear only once in our sample). Thus, of the 9 innovations that occur before the latest time period (i.e., before 700 BC), only 57% (n = 5) appear to have been retained, and appear in the pool of younger boards. The

IQV varies between 0, when all observations aré in a single category (i.e., an attribute fixed at one particular attri. bute state within a time period), to 1, when observations are evenl} split between all categories (i.e., boards are evenly split for ar attribute between all possible attribute states). IQV is not affectec by sample size and should be comparable across different data sets though as with most statistics, estimates of IQV for small sample sizes are less precise.

Fig. 3. The distribution of the game of fifty-eight holes. one board from the Southern Levant, dated to between the fourth and second century BC, was much younger than the remaining boards and was also dropped from the analysis. Thus, 90 boards grouped into five temporal categories were used for the analyses presented below.

Fig. 7. Historical contact and the transmission of the game of twenty squares. The oldest twenty squares boards, those dating before 1600 BC, are nearly homogenous. Several attributes are standardized across all boards within a time period (e.g., number of extra squares off main axis), while other attributes show just two different states (e.g., number of central squares). For example, Fig. 9 plots the number of extra squares off the main axis over time. As seen, prior to 1600 BC, all boards have 8 extra squares. Four innovations are evident after 1600 BC, with some boards containing 5, 10, 12, and 16 extra squares. The earliest of these innovations (16 extra squares) appears just after 1600 BC in Egypt and seems to have been successfully transmitted over time and space, continuing to appear

Fig. 11. Average IQV against the number of regions in which at least one board wa recorded. In support of Hypothesis 2b, Fig. 11 shows a positive relationship between the average IQV statistic for a period against the number of regions in which at least one board was recorded (r = 0.35; p = 0.09). This suggests a link between board variation and the
