  text: We report the complete analysis of a deterministic model of deleterious mutations
    and negative selection against them at two haploid loci without recombination.
    As long as mutation is a weaker force than selection, mutant alleles remain rare
    at the only stable equilibrium, and otherwise, a variety of dynamics are possible.
    If the mutation-free genotype is absent, generally the only stable equilibrium
    is the one that corresponds to fixation of the mutant allele at the locus where
    it is less deleterious. This result suggests that fixation of a deleterious allele
    that follows a click of the Muller’s ratchet is governed by natural selection,
    instead of random drift.

  text: In evolutionary game theory interactions between individuals are often assumed
    obligatory. However, in many real-life situations, individuals can decide to opt
    out of an interaction depending on the information they have about the opponent.
    We consider a simple evolutionary game theoretic model to study such a scenario,
    where at each encounter between two individuals the type of the opponent (cooperator/defector)
    is known with some probability, and where each individual either accepts or opts
    out of the interaction. If the type of the opponent is unknown, a trustful individual
    accepts the interaction, whereas a suspicious individual opts out of the interaction.
    If either of the two individuals opt out both individuals remain without an interaction.
    We show that in the prisoners dilemma optional interactions along with suspicious
    behaviour facilitates the emergence of trustful cooperation.

  text: Models of RNA secondary structure folding are widely used to study evolution
    in theory and simulation. However, systematic studies of the parameters involved
    are rare. In this paper, we study by simulation how RNA evolution is influenced
    by three different factors, namely the mutation rate, scaling of the fitness function,
    and distance measure. We found that for low mutation rates the qualitative evolutionary
    behavior is robust with respect to the scaling of the fitness function. For efficient
    mutation rates, which are close to the error threshold, scaling and distance measure
    have a strong influence on the evolutionary behavior. A global distance measure
    that takes sequence information additively into account lowers the error threshold.
    When using a local sequence-structure alignment for the distance, we observed
    a smoother evolution of the fitness over time. Finally, in addition to the well
    known error threshold, we identify another threshold of the mutation rate, called
    divergence threshold, where the qualitative transient behavior changes from a
    localized to an exploratory search.

  text: We have analysed the role of sampling drift in inducing shifts between alternative
    adaptive peaks, in small and rapidly growing populations. Using a simple model
    of disruptive selection on a polygenic character, we calculate the net probabilityofapeakshift.
    If the growth rate is high, theprobabilityofashiftina growing population is insensitive
    to selection on the character. Assuming that the character is effectively neutral
    during the brief initial increase, we find that theprobabilityofapeakshift is
    given by theprobabilityof finding a standard normal variate greater than √2ΔV
    where ΔV is the reduction in additive genetic variance during the growth period.
    This result holds for arbitrary pattern of increase in size, provided that the
    rate of increase is high enough for selection to be negligible, and the character
    depends on a large number of loci. Comparing theprobabilityofpeakshiftsin founding
    populations with the rate ofshiftsin static and allopatric populations it appears
    that although strongly selected shifts are only likely to occur ina growing population,
    a static population is a more congenial setting for adaptive shifts.

  text: We derive a formula giving thefrequency with which random drift shifts a population
    betweenalternativeequilibria. This formula is valid when such shifts are rare
    (Ns &gt;&gt; 1), and applies over a wide range of mutation rates. When the number
    of mutations entering the population is low (4Nμ &lt;&lt; 1), the rate of stochastic
    shifts reduces to the product ofthe mutation rate and the probability of fixation
    of a single mutation. However, when many mutations enter the population in each
    generation (4Nμ &gt;&gt; 1), the rate is higher than would be expected if mutations
    were established independently, and converges to that given by a gaussian approximation.
    We apply recent results on bistable systems to extend this formula to the general
    multidimensional case. This gives an explicit expression for thefrequencyof stochastic
    shifts, which depends only on theequilibrium probability distribution near the
    saddle point separating thealternative stable states. The plausibility of theories
    of speciation through random drift are discussed in the light of these results.

  text: It is noted that the sibling competition model for the evolution of sex and
    recombination, as it has been developed so far, involves truncation selection.
    After briefly reviewing aspects of the development and behaviour of such models
    an analytical treatment is presented which involves additive selection. Additive
    selection, as compared with truncation selection, decreases the advantage of sex
    to such an extent that it is unlikely that sibling competition could overcome
    its intrinsic two-fold cost, although it could still be important in promoting
    family variability produced by other mechanisms, such as polyandry.
