Abstract Theoretical studies of speciation have been dominated by numerical simulations aiming to demonstrate that in a certain scenario may occur. What is needed now shift focus identifying more general rules and patterns the dynamics speciation. The crucial step achieving this goal development simple dynamical models can be studied not only numerically but analytically as well. I review some existing analytical results on first show why classical theories peak shifts across adaptive...
Adaptive radiation is defined as the evolution of ecological and phenotypic diversity within a rapidly multiplying lineage. When it occurs, adaptive typically follows colonization new environment or establishment "key innovation," which opens niches and/or paths for evolution. Here, we take advantage recent developments in speciation theory modern computing power to build explore large-scale, stochastic, spatially explicit, individual-based model driven by adaptation multidimensional niches....
Although empirical evidence has shown that many male traits have evolved via sexual selection by female mate choice, our understanding of the adaptive value mating preferences is still very incomplete. It recently been suggested choice may result from females evolving resistance rather than attraction to males, but this disputed. Here, we develop a quantitative genetic model showing conflict over indeed results in joint evolution costly and exaggerated under wide range circumstances. In...
The fossil record displays remarkable stasis in many species over long time periods, yet studies of extant populations often reveal rapid phenotypic evolution and genetic differentiation among populations. Recent advances our understanding the population genetics evolutionary ecology point to complex geographic structure being fundamental resolution how taxa can commonly exhibit both short-term dynamics long-term stasis.
Significance How did human societies evolve from small groups, integrated by face-to-face cooperation, to huge anonymous of today? Why is there so much variation in the ability different populations construct viable states? We developed a model that uses cultural evolution mechanisms predict where and when largest-scale complex should have arisen history. The was simulated within realistic landscape Afroeurasian landmass, its predictions were tested against real data. Overall, an excellent...
Human behavior is strongly affected by culturally transmitted norms and values. Certain are internalized (i.e., acting according to a norm becomes an end in itself rather than merely tool achieving certain goals or avoiding social sanctions). Humans' capacity internalize likely evolved our ancestors simplify solving challenges-including ones. Here we study theoretically the evolutionary origins of norms. In models, individuals can choose participate collective actions as well punish free...
Abstract Willingness to lay down one’s life for a group of non-kin, well documented historically and ethnographically, represents an evolutionary puzzle. Building on research in social psychology, we develop mathematical model showing how conditioning cooperation previous shared experience can allow individually costly pro-group behavior evolve. The generates series predictions that then test empirically range special sample populations (including military veterans, college...
We review theoretical approaches for modelling the origin, persistence and change of social norms. The most comprehensive models describe coevolution behaviours, personal, descriptive injunctive norms while considering influences various authorities accounting cognitive processes between-individual differences. Models show that can improve individual group well-being. Under some conditions though, deleterious persist in population through conformity, preference falsification pluralistic...
Abstract We present a general quantitative genetic model for the evolution of reaction norms. This goes beyond previous models by simultaneously permitting any shaped norm and allowing imposition constraints. Earlier are shown to be special cases our model; we discuss in detail involving just two macroenvironments, linear norms, quadratic The predicts that, case temporally varying environment, population will converge on (1) genotype with maximum mean geometric fitness over all environments,...
It is well established that sexual conflict can drive an endless coevolutionary chase between the sexes potentially leading to genetic divergence of isolated populations and allopatric speciation. We present a simple mathematical model shows over mating rate result in two other general regimes. First, rather than “running away” from males, females diversify genetically into separate groups, effectively “trapping” males middle at state characterized by reduced success. Female diversification...
Geographic variation may ultimately lead to the splitting of a subdivided population into reproductively isolated units in spite migration. Here, we consider how waiting time until first split and its location depend on different evolutionary factors including mutation, migration, random genetic drift, architecture, geometric structure habitat. We perform large-scale, individual-based simulations using simple model reproductive isolation based classical view that evolves as by-product...
Conflict with conspecifics from neighbouring groups over territory, mating opportunities and other resources is observed in many social organisms, including humans. Here we investigate the evolutionary origins of instincts, as shaped by selection resulting between-group conflict presence a collective action problem. We focus on effects differences between individuals dynamics. Our theoretical models predict that high-rank individuals, who are able to usurp disproportional share within-group...
Parallel adaptation is common and may often occur from shared genetic variation, but the genomic consequences of this process remain poorly understood. We first use individual-based simulations to demonstrate that comparisons between populations adapted in parallel similar environments variation reveal a characteristic signature around selected locus: low-divergence valley centred at locus flanked by twin peaks high divergence. This initiated hitchhiking haplotype tracts differing derived...
A crucial step in recent theories of human origins is the emergence strong pair-bonding between males and females accompanied by a dramatic reduction male-to-male conflict over mating an increased investment offspring. How such transition from promiscuity to could be achieved puzzling. Many species would, indeed, much better off evolutionarily if effort spent on male competition was redirected increasing female fertility or survivorship Males, however, are locked "social dilemma," where...
