The Guppy Game: Understanding the big ideas of natural and sexual selection

Margaret Blattner, Barbara Hug, Patrick Watson, Donna Korol
2012 The Science Teacher  
They represent aspects of two of the big ideas in science: evolution and natural selection (NRC 2011). To help students understand these ideas, we developed the "Guppy Game."  ...  In this article, we describe the game and how we used it in an AP biology classroom to model the dynamic processes of population genetics and environmental influence on behaviors.  ...  Acknowledgments This project was supported by the National Center for Research Resources and the Division of Program Coordination, Planning, and Strategic Initiatives of the National Institutes of Health  ...

Mutation, Sexual Reproduction and Survival in Dynamic Environments [article]

Ruta Mehta and Ioannis Panageas and Georgios Piliouras and Prasad Tetali and Vijay V. Vazirani
2016 arXiv   pre-print
Using this machinery, we study the role of mutation in changing environments in the presence of sexual reproduction.  ...  Finally, we also show that in static environments, sexual evolution with mutation converges, for any level of mutation.  ...  In contrast, under sexual evolution with mutation the probability of long term survival is strictly positive.  ...

Why Darwin would have loved evolutionary game theory

Joel S. Brown
2016 Proceedings of the Royal Society of London. Biological Sciences  
Game theory clarifies aspects of ecological and evolutionary stability in ways useful to understanding eco-evolutionary dynamics, niche construction and ecosystem engineering.  ...  While natural selection provides the scientific basis for the fit of form and function, Darwin found certain adaptations vexing or particularly intriguing: sex ratios, sexual selection and altruism.  ...  theory, adaptive dynamics, G-functions, and other means for modelling and testing for the fit of form and function.  ...

The generation game is the cooperation game: The role of grandparents in the timing of reproduction

Rebecca Sear, Thomas E. Dickins
2010 Behavioral and Brain Sciences  
We then turn to the possible impact of grandparental acts of altruism, and examine whether benefits of grandparental care in industrialized societies may manifest in terms of less tangible dimensions,  ...  Although grandparents in industrialized societies continue to invest substantial amounts of time and money in their grandchildren, we find a paucity of studies investigating the influence that this investment  ...  Whereas evolutionary theorists may define parental investment as all the resources that parents invest in children to maximize their chance of survival to sexual maturity, it is well known that parents  ...

On the Evolution of Attitudes towards Risk in Winner-Take-All Games

Eddie Dekel, Suzanne Scotchmer
1999 Journal of Economic Theory  
A long-standing conjecture is that winner-take-all games such as patent races lead to the survival of risk-takers and the extinction of risk-averters.  ...  Using an evolutionary model of preference-formation, we investigate to what extent evolution leads to risk-taking in winner-take-all environments.  ...  Waldman (1995) develops an explicitly sexual model, where evolution can lead to \second-best adaptation."  ...

When and How Does Mutation-Generated Variation Promote the Evolution of Cooperation?

Mathias Spichtig, Martijn Egas
2019 Games  
Mutation-generated variation in behavior is thought to promote the evolution of cooperation.  ...  Here, we study this by distinguishing two effects of mutation in evolutionary games of the finitely repeated Prisoner's Dilemma in infinite asexual populations.  ...  Invasion Condition of TfT1 in X3-Defector Populations We study the fitness of a TfT1 individual in populations otherwise composed of defectors (full defection).  ...

Origin of biomolecular games: deception and molecular evolution

Steven E. Massey, Bud Mishra
2018 Journal of the Royal Society Interface  
In both biochemistry and molecular evolution, the important role of information asymmetry remains largely unaddressed.  ...  Thus, macromolecules do not need to possess information only to survive in an environment, but also to strategically interact with others by sending signals to a receiving macromolecule that can properly  ...  S.E.M. and B.M. designed the research and wrote the paper.  ...

Why war is a man's game

Alberto J. C. Micheletti, Graeme D. Ruxton, Andy Gardner
2018 Proceedings of the Royal Society of London. Biological Sciences  
These results reveal a potentially key role for ancestral conditions in shaping our species' patterns of sexual division of labour and violence-related adaptations and behavioural disorders.  ...  The qualitative observation that participation in warfare is almost exclusive to one sex is ultimately explained by the fundamentally sex-specific nature of Darwinian competition-in fitness terms, men  ...  Bowles, and the St Andrews Quantitative Biology Discussion Group, and four anonymous reviewers for helpful comments and discussion.  ...

Weini Huang, Christoph Hauert, Arne Traulsen
2015 Proceedings of the National Academy of Sciences of the United States of America  
This should be reflected in fluctuations of the population size even in constant environments.  ...  In contrast to previous game theoretic models, the carrying capacity of the population, and thus the population size, is determined by pairwise competition of individuals mediated by evolutionary games  ...  This should be reflected in fluctuations of the population size even in constant environments.  ...

How long do Red Queen dynamics survive under genetic drift? A comparative analysis of evolutionary and eco-evolutionary models

Hanna Schenk, Hinrich Schulenburg, Arne Traulsen
2020 BMC Evolutionary Biology  
Here, we recall the different mathematical approaches used in the current literature on Red Queen dynamics.  ...  Red Queen dynamics are defined as long term co-evolutionary dynamics, often with oscillations of genotype abundances driven by fluctuating selection in host-parasite systems.  ...  Funding We gratefully acknowledge generous funding by the Max Planck Society, which takes no part in the design, analysis or publication of research.  ...

On the evolutionary stability of male harassment in a coercive mating game

Oyita Udiani, Yuan Lou, Ian Hamilton
2016 Tamkang Journal of Mathematics  
Further, we argue based on these results that h * is an evolutionary stable male harassment level at which females will be ideally distributed to match the resource quality and social environments of their  ...  This article is a continuation of that work addressing the questions of stability at equilibria where males harass at the threshold level (i.e., h * ).  ...  Introduction Sexual conflict is ubiquitous in animals-a consequence of the often divergent reproductive strategies of the sexes.  ...
