Hominid Brain EvolutionSpringer Science and Business Media LLC - Tập 20 - Trang 67-79 - 2009
Drew H. Bailey, David C. Geary
Hypotheses regarding the selective pressures driving the threefold increase in the size of the hominid brain since Homo habilis include climatic conditions, ecological demands, and social competition. We provide a multivariate analysis that enables the simultaneous assessment of variables representing each of these potential selective forces. Data were collated for latitude, prevalence of harmful ...... hiện toàn bộ
Playing for keepsSpringer Science and Business Media LLC - Tập 15 - Trang 5-21 - 2004
Kerrie P. Lewis, Robert A. Barton
The hypothesis that play behavior is more prevalent in larger-brained animals has recently been challenged. It may be, for example, that only certain brain structures are related to play. Here, we analyze social play behavior with regards to the cerebellum: a structure strongly implicated in motor-development, and possibly also in cognitive skills. We present an evolutionary analysis of social pla...... hiện toàn bộ
Near the KnuckleSpringer Science and Business Media LLC - Tập 30 - Trang 272-298 - 2019
Robert King, Caoilfhionn O’Riordan
Irish Travellers constitute a pre-demographic-shift population living among a post-demographic-shift one. Their socio-medico profile identifies them as largely on fast life-history trajectories. In addition, they are strongly religious (typically using no contraception), highly sexually behaviorally dimorphic, with strong traditions of male-male competition (bare-knuckle fighting) and quasi-symbol...... hiện toàn bộ
Household and Kin Provisioning by Hadza MenSpringer Science and Business Media LLC - Tập 24 - Trang 280-317 - 2013
Brian M. Wood, Frank W. Marlowe
We use data collected among Hadza hunter-gatherers between 2005 and 2009 to examine hypotheses about the causes and consequences of men’s foraging and food sharing. We find that Hadza men foraged for a range of food types, including fruit, honey, small animals, and large game. Large game were shared not like common goods, but in ways that significantly advantaged producers’ households. Food sharin...... hiện toàn bộ
Fear of Violence among Colombian Women Is Associated with Reduced Preferences for High-BMI MenSpringer Science and Business Media LLC - Tập 30 - Trang 341-369 - 2019
Martha Lucia Borras-Guevara, Carlota Batres, David I. Perrett
Recent studies reveal that violence significantly contributes to explaining individual’s facial preferences. Women who feel at higher risk of violence prefer less-masculine male faces. Given the importance of violence, we explore its influence on people’s preferences for a different physical trait. Masculinity correlates positively with male strength and weight or body mass index (BMI). In fact, m...... hiện toàn bộ
The Origins of Prestige Goods as Honest Signals of Skill and KnowledgeSpringer Science and Business Media LLC - Tập 19 - Trang 374-388 - 2008
Aimée M. Plourde
This work addresses the emergence of prestige goods, which appear with fully modern Homo sapiens but at different times in different regions. I theorize that such goods came into existence to signal the level of skill held by their owners, in order to gain deference benefits from learning individuals in exchange for access. A game theoretic model demonstrates that a signaling strategy can invade a...... hiện toàn bộ
Height and reproductive success in a cohort of british menSpringer Science and Business Media LLC - Tập 13 - Trang 473-491 - 2002
Daniel Nettle
Two recent studies have shown a relationship between male height and number of offspring in contemporary developed-world populations. One of them argues as a result that directional selection for male tallness is both positive and unconstrained. This paper uses data from a large and socially representative national cohort of men who were born in Britain in March 1958. Taller men were less likely t...... hiện toàn bộ
