It is proposed that left handers have a frequency-dependent advantage in fights and for that reason a fitness advantage in some situations and this might explain the stability of left handedness.
Is there geographical variation in human handedness?
- M. Raymond, D. Pontier
- PsychologyLaterality
- 1 January 2004
Country always had a significant effect, consistent with substantial geographical variation of throwing and hammering handedness, and left‐handedness frequency estimates for a given country were not always consistent across datasets, perhaps due to missing variables, such as educational level or socio‐economic status.
Patterns and universals of mate poaching across 53 nations: the effects of sex, culture, and personality on romantically attracting another person's partner.

- PsychologyJournal of Personality and Social Psychology

It is concluded that human mate-poaching experiences are universally linked to sex, culture, and the robust influence of personal dispositions.

This study demonstrates that homogamy is present at the level of preferences for both sexes, and shows that measurements of the function describing thishomogamy are concordant with several distinct mating rules proposed in the literature.

Experimental evidence for the influence of group size on cultural complexity
- Maxime Derex, Marie-Pauline Beugin, B. Godelle, M. Raymond

It is found that when group size increases, cultural knowledge is less deteriorated, improvements to existing cultural traits are more frequent, and cultural trait diversity is maintained more often.
Can fertility signals lead to quality signals? Insights from the evolution of primate sexual swellings
- E. Huchard, A. Courtiol, J. Benavides, L. Knapp, M. Raymond, G. Cowlishaw
- BiologyProceedings of the Royal Society B: Biological…
- 22 May 2009
The findings show that once sexual swellings have evolved as fertility signals, they might, in certain socio-sexual systems, be further selected to act as quality signals, and suggest that mate choice for direct benefits (fertility) can lead to indirect benefits (good genes).

Evolutionary perspectives on the persistence of this polymorphism in humans are gathered for the first time, highlighting the necessity for an assessment of fitness differences between right- and left-handers.
