    • Calculating Evolutionary Dynamics in Structured Populations 

      Nathanson, Charles Gordon; Tarnita, Corina Elena; Nowak, Martin A. (Public Library of Science, 2009)
      Evolution is shaping the world around us. At the core of every evolutionary process is a population of reproducing individuals. The outcome of an evolutionary process depends on population structure. Here we provide a ...

    • The Evolution of Cell-to-Cell Communication in a Sporulating Bacterium 

      van Gestel, Jordi; Nowak, Martin A.; Tarnita, Corina (Public Library of Science, 2012)
      Traditionally microorganisms were considered to be autonomous organisms that could be studied in isolation. However, over the last decades cell-to-cell communication has been found to be ubiquitous. By secreting molecular ...

    • Evolution of In-Group Favoritism 

      Fu, Feng; Tarnita, Corina Elena; Christakis, Nicholas Alexander; Wang, Long; Rand, David Gertler; Nowak, Martin A. (Nature Publishing Group, 2012)
      In-group favoritism is a central aspect of human behavior. People often help members of their own group more than members of other groups. Here we propose a mathematical framework for the evolution of in-group favoritism ...

    • Evolutionary Dynamics in Set Structured Populations 

      Tarnita, Corina Elena; Antal, Tibor; Ohtsuki, Hisashi; Nowak, Martin A. (National Academy of Sciences, 2009)
      Evolutionary dynamics are strongly affected by population structure. The outcome of an evolutionary process in a well-mixed population can be very different from that in a structured population. We introduce a powerful ...

    • Evolutionary Dynamics in Structured Populations 

      Nowak, Martin A.; Tarnita, Corina E.; Antal, Tibor (The Royal Society, 2010)
      Evolutionary dynamics shape the living world around us. At the centre of every evolutionary process is a population of reproducing individuals. The structure of that population affects evolutionary dynamics. The individuals ...

    • Multiple Strategies in Structured Populations 

      Tarnita, Corina Elena; Wage, Nicholas; Nowak, Martin A. (National Academy of Sciences, 2011)
      Many specific models have been proposed to study evolutionary game dynamics in structured populations, but most analytical results so far describe the competition of only two strategies. Here we derive a general result ...

    • Mutation-Selection Equilibrium in Games with Multiple Strategies 

      Antal, Tibor; Traulsen, Arne; Ohtsuki, Hisashi; Tarnita, Corina Elena; Nowak, Martin A. (Elsevier, 2009)
      In evolutionary games the fitness of individuals is not constant but depends on the relative abundance of the various strategies in the population. Here we study general games among n strategies in populations of large but ...

    • Nowak et al. reply 

      Nowak, Martin A.; Tarnita, Corina; Wilson, Edward O. (Nature Publishing Group, 2011)
      Our paper challenges the dominant role of inclusive fitness theory in the study of social evolution1. We show that inclusive fitness theory is not a constructive theory that allows a useful mathematical analysis of ...

    • Prosperity is Associated with Instability in Dynamical Networks 

      Cavaliere, Matteo; Sedwards, Sean; Tarnita, Corina Elena; Nowak, Martin A.; Csikász-Nagy, Attila (Elsevier, 2012)
      Social, biological and economic networks grow and decline with occasional fragmentation and re-formation, often explained in terms of external perturbations. We show that these phenomena can be a direct consequence of ...

    • Strategy Selection in Structured Populations 

      Tarnita, Corina Elena; Ohtsuki, Hisashi; Antal, Tibor; Fu, Feng; Nowak, Martin A. (Elsevier, 2009)
      Evolutionary game theory studies frequency dependent selection. The fitness of a strategy is not constant, but depends on the relative frequencies of strategies in the population. This type of evolutionary dynamics occurs ...
