A simplified form of the quasispecies model of biological evolution is solved via a mapping onto a random flux model whose asymptotic behavior can be described in terms of a random walk. The statistics of the number of changes of the dominant species from a finite set of genotypes are exactly obtained confirming existing conjectures based on numerics.
