Another objection is the model does not account for beneficial mutations.

This is simple to address. We add a new variable, q, to be the probability a mutation is harmful.

Whereas in the original model, all mutations are harmful, with the addition of q, then the survival probability (s) is calculated as:

s = (1-pq)^L

where p is the probability a bit is flipped and L is the length of the organism.

Now, we can solve for q, giving us:

q = (1-s^(1/L))/p

In the limit as L approaches infinity (oo), the equation becomes:

q = (1-s^(1/oo))/p = (1-s^0)/p = (1-1)/p = 0/p = 0

The graph looks like:

This graph shows that as the length of the organism increases, almost all mutations become non-harmful. Value for p and s is 0.9.

This means that as the organism becomes more complex, then for a constant survival rate to be maintained most of the mutations must become non-harmful.
