The Blind Watchmaker Network: Scale-Freeness and Evolution
It is suggested that the degree distribution for networks of the cell-metabolism for simple organisms reflects a ubiquitous randomness. This implies that natural selection has exerted no or very little pressure on the network degree distribution during evolution. The corresponding random network, here termed the blind watchmaker network has a power-law degree distribution with an exponent gamma...

his tales from nineteenth century theology interspersed with recent experiments needing superglue to stick false tails on Kenyan widow birds to assess their mating potential! The Blind Watchmaker' is about evolution-^ specifically, the power of processes of cumulative seleC' tion to develop biological systems of amazing complex ity. It is a tightly argued exposition which sets out to defend the...

متن کاملSelective pressure on metabolic network structures as measured from the random blind-watchmaker network
A random null model termed the Blind Watchmaker network (BW) has been shown to reproduce the degree distribution found in metabolic networks. This might suggest that natural selection has had little influence on this particular network property. We here investigate to what extent other structural network properties have evolved under selective pressure from the corresponding ones of the random ...
متن کاملNot so Blind a Watchmaker Richard
Structural and operational principles underlying the organization of the vertebrate retina and bacterial flagellar apparatus are reviewed in the context of William Paley’s classic intelligent designer vs. Richard Dawkins’ contemporary “blind watchmaker” interpretations of biological origins and diversity. The significance of inverted retinal microanatomy and retinocytophysiology is diagnosed. I...
