Greenbeards are genes that can identify the presence of copies of themselves in other individuals, and cause their bearer to behave nepotistically toward those individuals. In recent years, a number of examples have been discovered, and it has been suggested that greenbeards represent one of the fundamental routes to social behaviors such as cooperation. However, despite their possible theoretical and empirical importance, many basic aspects of greenbeard biology are commonly misunderstood… 
Multicoloured greenbeards, bacteriocin diversity and the rock‐paper‐scissors game
TLDR
Analyzing strain dynamics using models of recurrent patch colonization and population growth finds that the factors that maintain simple RPS dynamics can also promote the coexistence of multiple toxin types (multiple beard colours), thus helping to explain the remarkable levels of bacteriocin diversity in nature.
A polychromatic ‘greenbeard' locus determines patterns of cooperation in a social amoeba
TLDR
It is shown that a locus of a social amoeba represents a polychromatic greenbeard, and patterns of natural Tgr locus sequence polymorphisms predict partner- specific patterns of cooperation by underlying variation in partner-specific protein–protein binding strength and recognition specificity.
The meaning of intragenomic conflict
TLDR
A general theory of intragenomic conflict is developed in which genes are viewed as inclusive-fitness-maximizing agents that come into conflict when their inclusive-Fitness interests disagree.
Variation at an adhesin locus suggests sociality in natural populations of the yeast Saccharomyces cerevisiae
TLDR
The results suggest this model yeast is surprisingly social in natural environments and is probably engaging in various forms of sociality, by using genomic data which provides a glimpse of otherwise unobservable interactions.
Antagonistic interactions subdue inter-species green-beard cooperation in bacteria
TLDR
The results suggest that P. aeruginosa engages in interference competition to suppress B. cenocepacia, indicating that inter-species conflict arising from dissimilarities at the genome level overrule the aligned cooperative interests at the pyochelin locus.
The effect of cheats on siderophore diversity in Pseudomonas aeruginosa
TLDR
It is seen that when all pyoverdine producers and cheats were co‐inoculated in well‐mixed environments, both types of pyoverDine producers were outcompeted, whereas spatial structure, rather than maintaining diversity, resulted in the domination of one py overdine producer.
Green beards in the light of indirect genetic effects
TLDR
This work uses models of indirect genetic effects (IGEs) to find the minimum correlation between the signaling and altruistic trait required for the evolution of the latter, and shows that this correlation threshold depends on the strength of the interaction, as well as the costs and benefits of the altruistic behavior.
Universitet Crozier ' s paradox revisited
Background: Organisms are predicted to behave more favourably towards relatives, and kin-biased cooperation has been found in all domains of life from bacteria to vertebrates. Cooperation based on
Discrimination Experiments in Entamoeba and Evidence from Other Protists Suggest Pathogenic Amebas Cooperate with Kin to Colonize Hosts and Deter Rivals
TLDR
In this review, the outcomes of in vitro pairwise discrimination/recognition encounters between seven Entamoeba lineages are relied on to discuss the biological significance of taxa, clone, and kin discrimination/ Recognition in a range of generalist and specialist species (close or distantly related phylogenetically).
A defense of sociobiology.
  • K. Foster
  • Biology, Medicine
    Cold Spring Harbor symposia on quantitative biology
  • 2009
TLDR
It is argued that semantic precision is required in discussing terms such as kin selection, group selection, and altruism, but once care is taken, the objections to the unity of theoretical sociobiology largely evaporate.

Selfish genes: a green beard in the red fire ant
TLDR
It is shown that BB queens initiating reproduction are killed by workers, and that it is primarily Bb rather than BB workers that are responsible for these executions.
Gestational drive and the green-bearded placenta.
  • D. Haig
  • Biology, Medicine
    Proceedings of the National Academy of Sciences of the United States of America
  • 1996
TLDR
Green-beard effects have many formal similarities to systems of meiotic drive and, like them, can be a source of intragenomic conflict.
Pedigree relatedness, not greenbeard genes, explains eusociality
TLDR
It is concluded that both phylogenetic studies and studies of intra-genomic conflict support the importance of pedigree relatedness in the evolution of eusociality.
What can microbial genetics teach sociobiology?
TLDR
The study of phoenix genes confirms a central theoretical prediction of social evolution: that genetic relatedness promotes cooperation and provides an important new perspective: that the genome-to-phenome mapping of social organisms might be organized to constrain the evolution of social cheaters.

TLDR
Wolbachia biology is reviewed, including their phylogeny and distribution, mechanisms of action, population biology and evolution, and biological control implications.
Altruism through beard chromodynamics
TLDR
This work model the green beard effect and finds that if recognition and altruism are always inherited together, the dynamics are highly unstable, leading to the loss of altruism, whereas if the effect is caused by loosely coupled separate genes, altruism is facilitated through beard chromodynamics in which many beard colours co-occur.
Ancestral Monogamy Shows Kin Selection Is Key to the Evolution of Eusociality
TLDR
It is found that mating with a single male, which maximizes relatedness, is ancestral for all eight independent eusocial lineages that are investigated, and monogamy was critical in the evolution of eussociality, strongly supporting the prediction of inclusive fitness theory.

  • 1986
TLDR
It is shown that polymorphism for the cues involved in recognition according to the above schemes is not maintainable if the only selection involved is that imposed by the recognition system itself.

TLDR
Grounds for thinking that the model described in the previous paper can be used to support general biological principles of social evolution are briefly discussed and a hypothesis is outlined concerning social evolution in the Hymenoptera.
Spiteful Soldiers and Sex Ratio Conflict in Polyembryonic Parasitoid Wasps
TLDR
A theoretical model for a prime candidate for a spiteful behavior, the production of the sterile soldier caste in polyembryonic wasps is developed and it is show that the biology of these soldiers is consistent with their main role being to mediate conflict over the sex ratio and not to defend against competitors and greater conflict will occur in more outbred populations.
