The problem is your mutate_genome() function which mutates the genome in place. So all the
living_species are using the same genome (they all reference the same list). The solution is to have
mutate_genome() copy the genome. You can do this by adding the line
a_genome = a_genome[:]
to the sta
sorry to inflict another dumb bug on you all so soon...
I have written a program to replicated simulate the evolution of
species and their genomes based on David Raup and Stephen Jay Gould's
1974 paper in systematic zoology 23: 305-322. The program correctly
evolves species and keeps track of
