我们发现，互利合作可以促进偏好的演变，与类似于自己的一个或几个任意的文化标签的个人进行交互。取得这一结果的一个必要条件是合作伙伴之间的不对称性，即其中一方（行动者）提出合作并选出合作伙伴，而另一方（接受者）从不拒绝合作，因为合作总是带来好处。具有优先分配等位基因的个体的优势在于，当分配位点与文化标签之间存在连锁不平衡时，可以获得更多的互利合作机会。一个特别有利的情况下，这种偏好的演变是一个细分的集合种群。在这种情况下，人口内的同质性和人口之间的差异是有利的，有利于种族群体的存在。(C)2006年爱思唯尔公司All rights reserved.
We show that mutual benefit cooperation can favor the evolution of a preference to interact with individuals that are similar to themselves with respect to one or several arbitrary cultural tags. One necessary requisite to obtain this result is an asymmetry between partners in such a way that one of them (actor) proposes the cooperation and elects the partner, whereas the other (receiver) never rejects the offer because cooperation always reports benefits. The advantage of individuals possessing allele for preferential assortment is due to receiving more offers of mutually beneficial cooperation when there is linkage disequilibriurn between the assortment locus and the cultural tags. An especially favorable scenario for the evolution of such preference is a subdivided metapopulation. In this case, the homogeneity within populations and the divergence between populations is favored, facilitating the existence of ethnic groups. (C) 2006 Elsevier Inc. All rights reserved.
