Table 1.

Genetic dissimilarity (below diagonal) and overall behavioural dissimilarity (above diagonal) in 36 pairs of chimpanzee groups. (For genetic dissimilarity, pairs classified as having statistically significant genetic dissimilarity are shown in bold and pairs living in the same block of continuous forest are shown in italics (see main text for details). For overall behavioural dissimilarity, values to the left of the backslash are normalized Hamming distances, and values to the right are Manhattan distances.)
