Social Slime Molds Meet Their Match
@article{Crespi2003SocialSM, title={Social Slime Molds Meet Their Match}, author={B. Crespi and S. Springer}, journal={Science}, year={2003}, volume={299}, pages={56 - 57} }
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][1] describe an elegant set of experiments ([Queller][2] et al .) that identify a green-beard gene encoding a homophilic adhesion protein in the slime mold Dictyostelium.
