Sorry for the terrible pun, but l’m legit curious.
A friend and I were talking about how some sourdough mothers, pho broths, etc can literally be human generations old. Is it a “Ship of Theseus” kind of thing? Does the process of maintaining the mother prevent this by adding in new yeast? Do the many generations of yeast make different strains of yeast? Is there a concern that the many yeast generations could create undesirable modifications?
In: Biology
Yeast is single celled and just clones itself.
Over years it will evolve to be well- adapted to a sourdough mother.
The undesirable mutations are generally gonna die out.
