Virchow’s cell theory contradicts the possibility of
spontaneous generation; living things are not generated from
decomposition of plant and animal matter. His maxim Omnis
cellula e cellula is an extension of omne vivum ex ovo
(“all that lives comes from an egg,” William Harvey,
1651) and omne vivum ex vivo (“all that lives comes
from life,” Francesco Redi, 1668). Also, it is thought that
Virchow plagiarized the idea from Robert Remak.
Virchow was opposed to Darwin’s theory of the origin
of species and declared that the Neanderthal bones were not from
an ancient human but only a modern man deformed by rickets,
arthritis, and heavy blows to the head. Even the best authorities
are subject to prejudices.
