- Do bacteria die of old age? 1 answer
I know that simple organisms containing of just few cells have no mechanism of dying because of aging. I guess, they typically die due to being out of food or due to becoming someone else's food.
Leaving aside the numerous theories of what can be the origin of such phenomenon as aging, I'm asking a simple question: what is the most primitive organism known so far which has the feature of aging and (as a consequence) dying, even if the environment is perfect?
