We present a new methodology to partition different sources of behavior change within a selectionist framework based on the Price equation – the Multilevel Model of Behavioral Selection (MLBS). The MLBS provides a theoretical background to describe behavior change in terms of operant selection. Operant selection is…

Sexual selection plays a crucial role in modern evolutionary theory, offering valuable insight into evolutionary patterns and species diversity. Recently, a comprehensive definition of sexual selection has been proposed, defining it as any selection that arises from fitness differences associated with nonrandom success…

Sexual selection is among the most pervasive and costly features of biological reproduction, reaching its greatest elaboration in lineages of greater complexity and capability—costs that signal a structural function not adequately accounted for by only the existing explanations focused on immediate adaptive benefits. I…

Most sexual selection models assume that the evolution of female choosiness is driven by indirect (genetic) benefits, such as the production of more viable offspring or more attractive sons. There is ample empirical evidence that female choosiness can also provide direct (non-genetic) benefits, including access to good…

Salience-driven exogenous and goal-driven endogenous attentional selection are two distinct forms of attention that guide selection of task-irrelevant and task-relevant targets in primates. During conflict i.e, when salience and goal each favor the selection of different targets, endogenous selection of the…

In evolutionary biology, sexual mating plays a pivotal role in facilitating the combination of beneficial alleles among individuals. Cross-species data suggest that organisms selectively choose mating partners based on factors such as genetic distance and partner fitness. Understanding the determinants of mate…

Attention mechanisms guide visuomotor behavior by weighing physical salience and internal goals to prioritize stimuli as choices for action. Although less well studied, selection history, which reflects multiple facets of experience with recent events, is increasingly recognized as a distinct source of attentional…

Sexual selection operates across pre- and post-copulatory episodes, driven by intra-sexual competition and inter-sexual choice for mates or gametes. In females, sexual selection often manifests as choosiness, however pre- and post-copulatory preferences can be in opposing directions. While relationships between male…

Over the last few decades, the developing field of primate archaeology has used archaeological methods to reconstruct primate behaviors, especially tool use. We expand the possibilities of primate archaeology with an inverse approach: using living primates to address archaeological questions. In particular, we…

Polyandrous mating systems result in females mating with multiple males. This includes the potential for unintended matings and subsequent sperm competition with hybridizing species, especially in the presence of alternative reproductive tactics (sneaker males). Cryptic female choice allows females to bias paternity…

The antagonistic sexual coevolution of the sexes (i.e., sexual conflict) is a key theme in the study of the evolution of mating systems. Specifically, studying the modifications of sexual behavior in the context of ecological conditions is fundamental for understanding the formation of a sexual system. The extremely…

Suppose that females choose males based on attributes that do not signal any genetic quality that is not related to the choice itself. Can being choosy confer selective advantage in this situation? We introduce correlated strategies, which means that females, when making their choice, may take into consideration…

Three main mechanisms have been proposed to explain divergent decisions between species faced with the same options: differences in sensory abilities, attentional capacities, or cognitive evaluations. While these mechanisms have been well-established in controlled settings, there is limited empirical evidence regarding…

Male-male competition and female mate choice are often assumed to act in concert, with male social dominance serving as a reliable cue in female choice reflecting overall male quality. However, few studies have explicitly disentangled the effects of male competition and female mate choice, leaving gaps in our…

Mate quality and the cost of mating affect the evolution of mating preferences and is one reason females often show stronger mate preferences than males. Fungus gnats in the family Sciaridae (Diptera) are a family in which we might expect to see the evolution of strong male mate preferences. Many Sciaridae species are…
