...This chapter considers a simple and general model of natural selection: replicator dynamics. Many animal traits and behaviors are social, in that they affect the reproductive success not just of the animal performing the behavior, but also conspecifics. Mathematical theories based on classical...

...This chapter examines the factors that affect the timing and patterning of flowering, as well as the effects of different flowering patterns on pollination outcomes. Plants should flower in ways that maximize their own reproductive success. The “flowering pattern” is a composite of the timing...

... models can be constructed to deal with reproductive value and class-structured populations. It also shows how costs and benefits can be expressed as payoffs that are proportional to reproductive success, as changes in production of offspring, or as changes in evolutionary fitness. Finally, it presents...

..., inherited differences must affect reproductive success. The chapter proceeds by assessing the implications of these changes within species for agriculture. It also gives an example of how populations evolve by natural selection and concludes with an analysis of the evolution of transfer RNA genes via less...
