Genetic analyses suggest SARS‑CoV‑2 originated from bat
coronaviruses with possible adaptation in intermediate mammalian hosts.
Replication in these hosts allows viral evolution toward efficient interaction
with mammalian ACE2‑like receptors, without eliminating the virus’s ability to circulate in reservoir species.

Over time, what consequence does this process most strongly
promote?
