Cooperation Among Animals: An Evolutionary Perspective
TLDR
The evolution of cooperation in mammals I: non-primates and non-human primates and theoretical perspectives on the evolution of Cooperation in fishes, birds and insects are presented.
Sexual Selection and Imitation: Females Copy the Mate Choice of Others

  • 1 June 1992
TLDR
Female copying behavior during mate choice in the Trinidadian guppy is examined, which shows that female mate copying behavior increases the variance in male reproductive success and thus the potential for sexual selection.
Aggressive interactions and inter-contest interval: how long do winners keep winning?.
. Considerable evidence across many taxa demonstrates that prior social experience affects the outcome of subsequent aggressive interactions. Although the 'loser effect', in which an individual
Winner and loser effects and the structure of dominance hierarchies
TLDR
A computer simulation is developed to examine winner and loser effects when such effects are independent of one another (as well as when they interact) and when combatants assess each other's resourceholding power.
Inclusive fitness theory and eusociality
TLDR
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
Can altruism evolve in purely viscous populations?
TLDR
A computer simulation model of ‘pure’ population viscosity is analysed, in which offspring are always deposited close to parents and no global mixing stage exists, which generates a high coefficient of relatedness among interacting individuals.
Group Selection and Assortative Interactions
TLDR
This work presents a series of models in which altruism is a continuously varying trait and individuals are free to choose their associates, based on information that is acquired through experience, observation, or cultural transmission, favoring the evolution of altruism and other group-level adaptations among genealogically unrelated individuals.
Prey approaching predators : a cost-benefit perspective
TLDR
The costs and benefits of approaching predators are reviewed, and a game theory model of prey approaching potential predators is presented, which predicts the equilibrial frequency of 'approachers' and 'non approacher' and the (relative) mean approach distance (as a function of group size).
Interface between culturally based preferences and genetic preferences: female mate choice in Poecilia reticulata.

  • 2 April 1996
TLDR
This experiment provides the first attempt to experimentally examine the relative strength of cultural and genetic preferences for a particular trait and suggests that these two factors moderate one another in shaping social behavior.
