Query: Too much author; too little subject

In my experience, scientists are a modest lot. Unfortunately, some science popularists seem to have an ego the size of all outdoors. However, if you have the patience to battle your way through the I said..., I did..., I am..., then McMenamin's book contains a few interesting snippets for anyone interested in the Vendian biota.Alternatively, you could read Chapter 3 of "Major Events in the History of Life" (Ed. by J. William Schopf and available from Amazon) in which Bruce Runnegar writes about the fossils (rather than about Bruce Runnegar.)
