Mutation rate in cyanobacteria

Data and annotations in CyanoBase (September 2009)
Nucleotides 266 584 858 1 That is the size of the Cyanobacteria genome, their genome hosts 260 million base pairs

Within the cyanobacterium life cycle, cyanobacteria undergo cell division approximately once per day under the influence of moderate constant light and through intensifying the light, the cells start dividing more frequently as more energy is available. It takes about 19 hours for the cyanobacteria to rest before it can process cell division once more. 2

Bacterial DNA Mutations 3
Spontaneous mutations occur at a rate of 1 in 10^5 to 10^8 and contribute to random population variation.

that is, if we suppose the lowest mutation ration, one mutation in every 100mio base pairs 100.000.000, in other words, 2,5 mutations per cell cycle.

If the first fully developed cyanobacteria emerged 3 billion years ago, and they replicate once per day, that means, there were years x 360 days = 1080000000000 or 10,8 ^11 replication cycles. Now lets multiplicate this 2,5, since there were 2,5 mutations per cycle, that means, there would have had to be 2,700.000.000.000 or 2,7^11 mutations during this time period.

Since the genome size is 260 mio base pairs:

That means, they would have changed their genome 100%, 10150 times

We should expect to see a completely different organism. But here they are....
