One of the excellent 'Science Masters' series, this is an attempt to explain how evolution actually works. The river referred to in the title is the DNA streaming through the ages, splitting and dividing as it goes and although it is slightly disconcerting to come to regard yourself merely as a tool for its replication (no higher purpose here!) I can heartily recommend this as a fascinating, easily accessible and very entertaining read.
