Oh FFS. They could evolve without the ability to transfer plasmids between
cells. It would just be slower.

How, when the cell divides into two parts identical to the one that
went before?

Your assumption that both cells must always be identical is wrong. Also
after the cells have divided each may experience different mutagenic
events. for example one may get hit by ionising radiation, the other not.

Point mutation and transcription errors tend to be the greater causes of
variation. DNA repair and replication is good but it's not perfect.

If you had thought about it you would have realised that.
