natural selection produces changes most quickly in
1 species with short reproductive cycles
2 individual pathogens killed by antibiotics
3 complex multicellular organisms
4 individuals that produce a small number of offspring

Respuesta :

i have reason to believe that 2 is the answer, because since all individual pathogens are the same, they will all react in the same way to the antibiotic. thus natural selection will exterminate them the fastest.
