Actually, that isn't my point. In mathematical terms, you would not only have to reproduce the initial conditions using species from three billion years ago, but you would also have to reproduce the boundary conditions of climate, other species, etc.

If you have some additional explanation, then give it. Otherwise your doubts are meaningless.

Can we do repeatable experiments on plate tectonics? Planetary motion? Also, we can do experiments on natural selection over shorter time periods, such as the emergence of antibiotic-resistant bacteria. Indeed, if you insist on explaining three billion years of life by any hypothesis, how could that hypothesis be subject to experiment?

My best answer is; I do not know, maybe it could, maybe it could not. See, I have no repeatable experiments or theory to show that it would be possible.

And why do you cling to repeatable experiments? You have already admitted that natural selection occurs. Do you have anything to add?

If you don't believe that natural selection was the only/main cause of the change in life forms over the last three billion years, then feel free to posit an alternative. You will have to show not only that the alternative explains these changes, but that it occurs in the first place.

I also know how natural selection affects fitness over time in naive simulations, sometimes I get continuous improvement in fitness with no end in sight and sometimes it stops with no chance of improvement in fitness.

Would evolutionists claim that improvement is continuous? Also, what constitutes an improvement depends on the background environment as well as other organisms. Nature may select for local improvements, but changes in background conditions may render such changes to be nonimprovements.

I'm honest enough to say that I have no idea what natural selection would cause over 3 billion years on this earth. Maybe you should admit that you do not know either.

I don't recall claiming to know. Indeed, do people such as Dawkins claim to know?

Natural selection is not so much a theory but a recognition of mortality and its correlation (however weak) with genetics.

Are you admitting that natural selection occurs?

You can only assume it causes exactly what we can observe and then claim that as evidence. Unfortunately, that does not make any sense.

It is not the particular outcomes that count as evidence of natural selection, but mortality and the correlation between mortality and genetic makeup..

But how extensible are the methods shown? Would they work with larger numbers? Would they work for adding seven numbers?

Also, I have issues with the claim that addition shouldn't be algorithmic.

"number sentences" versus "equation"

Are all number sentences equations? What about "7 is a prime number."?

Is making tens easier than carrying?

There may be large blind spots in parents' understanding of the commutative and associative properties of addition, but these examples aren't helping. For the commutative property, use an example. We are to pay $15 for an item using a $5 bill and a $10 bill. Does it matter whether we first hand over the $5 bill and then the $10 bill or first hand over the $10 bill and then the $5 bill? For the associative property, use three bills paperclipped together in the different ways..
