Sperm Competition and Its Evolutionary Consequences in the Insects
- L. Simmons
- 1 December 2001
Ashot on goal does not ensure victory*.Likewise, insemination does not guaranteepaternity. When females store sperm fromseveral males, each male’s fitness dependson his ability to tilt the ensuing… Expand
Sexual selection and mate choice.
The past two decades have seen extensive growth of sexual selection research. Theoretical and empirical work has clarified many components of pre- and postcopulatory sexual selection, such as… Expand
The Evolution of Polyandry: Sperm Competition, Sperm Selection, and Offspring Viability
- L. Simmons
- 10 November 2005
▪ Abstract In contrast to Bateman's principle, there is now increasing evidence that female fitness can depend on the number of mates obtained. A number of genetic benefits have been proposed for the… Expand
10 – Sperm Competition in Insects: Mechanisms and the Potential for Selection
The chapter focuses on the understanding of the mechanisms of sperm competition, which are essential for interpreting nonrandom patterns of paternity and for predicting the types of adaptations that… Expand
Does sexual dimorphism in human faces signal health?

- 7 August 2003
Evolutionary psychologists suggest that a preference for sexually dimorphic traits in human faces is an adaptation for mate choice, because such traits reflect health during development. For male… Expand
Sperm competition: linking form to function
BackgroundUsing information from physics, biomechanics and evolutionary biology, we explore the implications of physical constraints on sperm performance, and review empirical evidence for links… Expand
SPERM COMPETITION GAMES: A GENERAL MODEL FOR PRECOPULATORY MALE–MALE COMPETITION
- G. A. Parker, C. M. Lessells, L. Simmons
- Biology, Medicine
- Evolution; international journal of organic…
- 1 January 2013
Reproductive males face a trade‐off between expenditure on precopulatory male–male competition—increasing the number of females that they secure as mates—and sperm competition—increasing their… Expand
Reactive oxygen species as universal constraints in life-history evolution
Evolutionary theory is firmly grounded on the existence of trade-offs between life-history traits, and recent interest has centred on the physiological mechanisms underlying such trade-offs. Several… Expand
Attractiveness and sexual behavior: Does attractiveness enhance mating success?
Abstract If attractiveness is an important cue for mate choice, as proposed by evolutionary psychologists, then attractive individuals should have greater mating success than their peers. We tested… Expand
