The kallikrein-1 serine protease toxins found in solenodon venom evolved convergently with similar toxins found in venomous shrew venom.
Notes on verification
Directly confirmed by peer-reviewed PNAS study (Casewell et al. 2019) and corroborated by independent science journalism and academic sources; no contradicting evidence found.
