    Kenichi Aoki
    Department of Biological Sciences, The University of Tokyo, Bunkyoku, Tokyo, Japan
    Ann Hum Biol 29:589-608. 2002
    ..Such a preference would generate sexual selection for light skin that counteracts natural selection for dark skin. The observed latitudinal gradient in skin colour may result from the balance between natural and sexual selection...

    Joe Yuichiro Wakano
    Department of Biological Sciences, The University of Tokyo, Hongo 7 3 1, Bunkyoku, Tokyo 113 0033, Japan
    Theor Popul Biol 66:249-58. 2004
    ..Our results are consistent with the predictions of previous studies. In addition, we identify a critical level of environmental constancy below which only individual and social learners are present...

    Theor Popul Biol 82:38-47. 2012
    ..When the number of acquaintances is small relative to the population size, we find that a change in the innovation rate contributes more than a proportional change in population size to the cumulative cultural evolution of skill level...

    Ann Hum Biol 39:28-35. 2012
    ..Homogamy for body height has been repeatedly documented in Western societies. Nevertheless, the underlying mechanism is unclear and the reasons for its apparent absence in non-Western societies remain unexplained...

    Theor Popul Biol 61:73-81. 2002
