You are thinking “wait a second, you can’t just evolve resistance to stuff. Individuals don’t evolve, species do.”
Typically, that’s a fair characterization of evolution. But bacteria have a lot of horizontal gene transfer
, so you can evolve
your very own antibiotic resistance just by borrowing the right plasmid
from a buddy bacteria.
Another example of evolution on an individual basis is Pokemon.
Whoops! I meant Poke’mon.
