Recent microbiological research demonstrates that bacteria do experience aging and senescence, often driven by asymmetric cell division and the accumulation of cellular damage.

The analysis

Multiple retrieved papers provide empirical evidence and reviews establishing that bacteria undergo aging processes akin to senescence, featuring asymmetric division and functional decline.
