We reconsider the mean-field Hamiltonian of the Ising quantum chain as a mutation-selection model of biological evolution. Direct calculation of its Perron-Frobenius eigenvector reveals a fundamental difference between the quantum-mechanical and probabilistic applications, and partially corrects previous results.
