    • ...Social explanations focus on intragroup competition, where extra time is necessary to develop social competency (Dunbar, 1998; Barton, 1999)...

    • ...Based on previous analyses (e.g., Sawaguchi, 1992; Dunbar, 1996; Barton, 1999), but including more ecological variables, our general prediction is that various measures of relative brain size, in addition to age at first reproduction as a proxy for the end of the growth period, will be positively associated with indices of social and foraging complexity within and across primate clades...
    • ...In support of this idea are strong relationships among longer juvenile periods in primates and various measures of relative brain size (Barton, 1999)...
    • ...In the same vein as Barton (1999) ,w e focus on multiple regressions that allow us to simultaneously examine brain-size variation explained by diet and group size...
    • ...Interpreting the brain and higher cortical functions as adaptations for negotiating social interactions within large-group settings has been widely discussed (Jolly, 1966; Humphrey, 1976; Whiten and Byrne, 1988; Byrne and Whiten, 1988; Alexander, 1989; Dunbar, 1993, 1998, 2003; Byrne, 1995; Kummer et al., 1997; Whiten and Byrne, 1997; Heyes, 1998; Barton, 1999; Flinn et al., 2005) and offers an alternative (or perhaps complementary) ...
    • ...The data base was compiled from secondary sources (Barton, 1999; Harvey et al., 1987; Smith and Jungers, 1997; Kappeler and Pereira, 2003) with an emphasis on primary field data where available (Kaplan et al., 2003; see http://www.unm.edu/%7Ehkaplan/pnas/primatedatabase...
    • ...The best measure of relative brain size is still debated (Barton, 1999; Deaner et al., 2000), but we included ratios that exclude the cerebellum to avoid the problem that larger neocortices could be driven by diminished cerebella (Reader and MacDonald, 2003)...
    • ...This result contrasts with previous work supporting a correlation between brain size and diet across primates (Clutton-Brock and Harvey, 1980; Foley and Lee, 1992), including studies in which multiple regression was used to demonstrate that diet and group size independently explain variation in brain size (Barton, 1999) and neocortex ratio (Dunbar, 1996)...

    • ...There are also associations among these variables and the elaboration of costly parenting practices, delayed sexual maturation, and a prolonged juvenile period in which social learning is of great importance (Barton, 1999; Eisenberg, 1981; Jerison, 1973; Johanson & Edey, 1981; Richerson & Boyd, 2000)...

    • ...Comparative biology can be illustrated by studies on a number of animal groups, such as primates [Clutton-Brock and Harvey, 1980; Dunbar, 1998; Barton, 1999], rodents, insectivores and lagomorphs [Mace et al., 1981], carnivores [Gittleman, 1986; Dunbar and Bever, 1998], bats [Eisenberg and Wilson, 1978], cetaceans [Marino, 1996], birds [Bennett and Harvey, 1985a; Madden, 2001], and fish [Huber et al., 1997]...

    • ...Comparative research indicates that brain size and length of the developmental period covary with complexity of social relationships across species of living primate (Barton, 1996, 1999; Joffe, 1997)...
