Abstract

How green is your beard? The evolution of altruism, especially as directed to non-kin, is an enigma of evolutionary biology. Explanations would come easier, however, if altruists were readily recognized. Arguably the simplest recognition system is a conspicuous, heritable tag. A green beard would do it. A few examples of the ‘green beard effect’ have been reported in human interactions, though beards per se and greenness tend not to feature. A problem with this explanation is the improbability of one gene encoding all three functions (altruism, tag and recognition). Based on modelling, Jansen and van Baalen identify a further problem with this theory: even if green beard genes can be selectively advantageous, altruism is unstable under previous assumptions. But, they add, the evolution of cooperation using a recognition mechanism may be more likely if many beard colours coexist.
