Evolutionary changes in protein interactions among Donggyeong dog tail-specific proteins against a total of 2,218 protein pairs (A) and non-tail-specific proteins against a total of 2,539 protein pairs (B). Numbers on branches represent the number of newly appeared (in the case of +) or disappeared (in the case of −) protein interactions. Percentages in parentheses indicate fraction against the number of protein pairs without interaction (in the case of +) or the number of protein pairs with interaction (in the case of −). Two numbers next to names of ancestors or above names of descendant species mean the number of protein pairs with or without interaction, respectively. Divergence time among species was obtained from the TimeTree website (http://www.timetree.org/).
