Hi crash,

Yes. All clones of a single individual, called the "founding individual."
Where does the statement found
Here say what you said?
1. Bacteria are spread out on a plate, called the original plate.
I don't think that 1. means 1 bacteria.
I understand the statement to mean more than one as they are to be spread out on a plate.
It nowhere says all these bacteria was from a single bacteria.

The antibiotic resistance was acquired during the initial culture
That is an assumption.
Since the so called single individual that is your founding individual was not exposed to penecilin you have no way of knowing whether that individual had an immunity to penecilin.

We observed neither of those. We observed that some colonies replicated and some did not -
Yes that is obvious as all did not survive when exposed to penecilin.

thus proving that resistance was an acquired trait, acquired during the "log phase" of the experiment (the initial culture
Well no there has been no proof that the trait was acquired during the "log phase".
It is proof that something has occured.
Either the original single individuall bacteria as you put forth had to have no immunity and some of its offspring gained immunity or the original single individual bacteria posessed immunity and then some of the offspring lost that immunity and their offspring did not have the immunity.
We are in agreement that the bacteria that survived had the immunity prior to exposure to penecilin.
We just don't agree on how that immunity began to exist.
My question then is if the immunity was not in the DNA how did any bacteria survive until today?
It makes no difference what antibiotic science can come up with there are bacteria that are already immune to that antibiotic.
That supports that the DNA has those immunities already in it.

This proves that random mutation was the source of the acquired resistance.
One assertion does not prove another assertion.
There are two possibilities.
One possibility is that the immunity trait was acquired.
The other possibility is that the original individual had immunity and some of the offspring and their offspring did not receive that immunity due to a bad mutation.
God Bless,
