Richard Dawkins: "The extended phenotype allows that cascade of causal arrows to reach out beyond the body wall. Extended phenotypes are things like birds' nests, or bower-bird bowers. A peacock has a tail with which it woos females. A male bower bird builds a grass tail, a bower, in the bushes, and dances around it, and that's what attracts the females. That bower made of grass is performing exactly the same role as a peacock's tail. Genes that make for a good bower, a pretty bower, get passed on to the next generation. The bower is a phenotypic effect of genes. It's an extended phenotype." So a bird in the bush is worth two in the hand? Len http://www.mp3.com/LenBullard Ekam sat.h, Vipraah bahudhaa vadanti.
