  abstract =     "The concept of neutral evolutionary networks being a
                 significant factor in evolutionary dynamics was first
                 proposed by Huynen {\em et al.} about 7 years ago. In
                 one sense, the principle is easy to state -- because
                 most mutations to an organism are deleterious, one
                 would expect that neutral mutations that don't affect
                 the phenotype will have disproportionately greater
                 representation amongst successor organisms than one
                 would expect if each mutation was equally likely. So it
                 was with great surprise that I noted neutral mutations
                 being very rare in a visualisation of phylogenetic
                 trees generated in {\em Tierra}, since I already knew
                 that there was a significant amount of neutrality in
                 the Tierra genotype-phenotype map. It turns out that
                 competition for resources between host and parasite
                 inhibits neutral evolution.",
