Color naming in natural languages is not arbitrary: it reflects efficient partitions of perceptual color space modulated by the relative needs to communicate about different colors.

The concept of fitness is central to evolution, but it quantifies only the expected number of offspring an individual will produce.

We apply this theory to analyze how mechanisms known to promote cooperation within a single group -- including assortment, reciprocity, and population structure -- alter evolutionary outcomes in the presence of competition among groups.

We show that a group initially comprising a minority of the population may nonetheless overtake the entire population--especially if it adopts the Stern Judging norm, which assigns a bad reputation to individuals who cooperate with those of bad standing.

There is a critical number of signaling molecules at which the efficiency of the two mechanisms are the same.

When success is measured as payoff in a game played against another learner, mutual selfishness typically fails to produce the optimal outcome for a pair of individuals.

We find that strong selection for mito-nuclear compatibility reduces the equilibrium number of species after a radiation, increases the species' abundances, while simultaneously increasing both speciation and extinction rates.

We then empirically test people's preferences for accuracy in the news.

Forecasting types can invade but not overtake the population, producing a stable coexistence with myopic types.

The form of political polarization where citizens develop strongly negative attitudes towards out-party policies and members has become increasingly prominent across many democracies.

We develop a maximum-likelihood method to infer the precise form of FDS from time series of trait abundance, and we apply the method to data on baby names and pet dog breeds over the last century.

Here we derive the theoretically optimal strategy for using a time-limited intervention to reduce the peak prevalence of a novel disease in the classic Susceptible-Infectious-Recovered epidemic model.

Languages and genes are both transmitted from generation to generation, with opportunity for differential reproduction and survivorship of forms.
