Table 2.

Order of acquisition diffusion analysis (OADA) results. Support ratios for each network are shown. Results in italics indicate the networks with a support ratio of greater than 2 (i.e. networks that provide at least 2× more support for social transmission relative to asocial learning). For the affiliative interaction and the proximity networks, we also provide the support ratios for the specific behaviours that make up each of these two networks.
