This isn't the case. There are effectively an infinite number of
possible mutations. I think people who haven't worked in genetics
tend to think in terms only of point mutations and it may be true
that something like all possible point mutations are sampled in a
large enough population. I don't know that I've ever seen the
question dealt with. There is a large difference in the rate at which
particular point mutations occur at particular positions, so I doubt
that even all possible point mutations are sampled, except possibly
in large microbial populations. When you consider that there are 3
billion positions in the human genome and for most of our history the
population was much less than that, and that the number of new
mutations per individual is not that high, it is clear that all the
possible point mutations can only be sampled over a fairly long
period of time.
But when you consider all the possible insertions or deletions,
inversions of large or small segments, rearrangements, transposition
of the whole sequence or a fragment of any of the thousands of
transposable elements to any position in the genome, sometimes
carrying pieces of flanking DNA with them, insertion of virus DNA,
occassional insertion of bits of other foreign DNA, etc., etc, etc, I
would say that there is no doubt that nothing approaching saturation
of "all possible mutations" occurs. Reality is that countless complex
mutations occur, many of which are unique - they will never occur
again. And, perhaps counterintuitively, many of these complex
mutations are not selected against, because we see evidence of large
numbers of them in the genome. Every one of the millions of
transposon and virus relics in the human genome is a record of a
complex mutation that got fixed in the population.
Put on top of this that what happens to a particular mutation is
dependent on its context - what is the seqence of the rest of the
genome? Whether a particular mutation encounters positive, negative
or no selective pressure depends on the state of other genes in
genome, the immediate environment of the individual in which it
occurs and the contingent events that the individual encounters. If
you get hit by a bus when you are 3, it doesn't matter that you had a
mutation that would have made you the next Einstein. It also depends
on what genomes the mutation gets assorted and recombined into
in subsequent matings.
This is why I say that we need to think about how we know that any
event is a matter of "chance," particularly unique events, because
genetics and evolution are full of them. With quantum level events in
the simple systems that physicists study, you can repeat the
experiment a large number of times and characterize the statistics
carefully and after decades of argument and increasingly
sophisticated experiments make a case that there are no hidden
variables that determined what happened and that something has
happened by pure "chance," but even then I don't see how you can rule
out or in that God has simply detemined directly what a particular
electron did.
So how do you determine that for a mutation? We can look at the whole
process and say intuitively that since it gave rise to something as
weird and wonderful as us, it must not have been chance. But that
isn't science, it's philosophy or theology or faith. And if someone
else says that they have the opposite intuition about it, that
chance and recombination and differential reproduction are enough, I
doubt that an argument is what will get them to see it our way. It
takes something deeper than argument.
