}Biologists have debated the existence of altruistic genes that recognize and aid copies of themselves. However, demonstrating such "green-beard" genes in biological systems has proved difficult. In their Perspective,
Crespi and Springer
describe an elegant set of experiments (Quelleret al.) that identify a green-beard gene encoding a homophilic adhesion protein in the slime mold Dictyostelium.

Cadherins in maternal–foetal interactions: red queen with a green beard?
- Biology, MedicineProceedings of the Royal Society B: Biological Sciences

Support is provided for the hypothesis that the cadherin genes involved in maternal–foetal interactions have been subject to green-beard-effect mutations over the course of evolutionary history, leading to antagonistic coevolution with suppressing elements from the parliament of genes.

Selective pressures for accurate altruism targeting: evidence from digital evolution for difficult-to-test aspects of inclusive fitness theory
- Biology, Computer ScienceProceedings of the Royal Society B: Biological Sciences
- 2010
Evidence from digital evolution is provided in support of natural selection favours altruist genes that are increasingly accurate in targeting altruism to only their copies by competing multiple altruist-targeting mechanisms that vary in their accuracy in determining whether a potential target for altruism carries a copy of the altruist gene.
How is human cooperation different?
- Business, MedicinePhilosophical Transactions of the Royal Society B: Biological Sciences

It is argued that humans, in contrast to all other species, employ a wider range of enforcement mechanisms, which allow higher levels of cooperation to evolve and stabilize among unrelated individuals and in large groups.

This work is the first example of secondary contact and hybridization between two ecologically-distinct species resulting in positively selected divergence of a mate recognition trait whose genetic basis is known and is therefore of some general importance to evolutionary biology.

Single-Gene Greenbeard Effects in the Social Amoeba Dictyostelium discoideum
- Biology, MedicineScience
- 2003
The csA gene inDictyostelium discoideum acts as a single-gene greenbeard, and when wild-type cells are mixed with csA-knockout cells, the wild type is more altruistic, but is also able preferentially to direct the benefits to other wild- type cells.

Green-beard effects have many formal similarities to systems of meiotic drive and, like them, can be a source of intragenomic conflict.

The probable altruistic behaviour of spermatozoa in an eutherian mammal, Apodemus sylvaticus, is reported, which displayed a unique morphological transformation resulting in cooperation in distinctive aggregations or ‘trains’ of hundreds or thousands of cells, which significantly increased sperm progressive motility.

A genetical mathematical model is described which allows for interactions between relatives on one another's fitness and a quantity is found which incorporates the maximizing property of Darwinian fitness, named “inclusive fitness”.
Integrins, cadherins, and catenins: molecular cross‐talk in cancer cells
- Biology, MedicineThe Journal of pathology

Intercellular and cell–matrix adhesion mediated by cadherin/catenin and integrins is likely to play a role in the control of both structural morphology and functional differentiation; hence, any loss of this control mechanism may well facilitate the neoplastic process.
