Long-accepted theory of vertebrate origin upended by lamprey fossils
Newly discovered fossils of fish from multiple life stages may ‘rewrite textbooks’ A new study out of the University of Chicago, the Canadian Museum of Nature and the Albany Museum challenges a long-held hypothesis that the larvae of modern lampreys are a holdover from the distant past, resembling the ancestors of all living vertebrates, including ourselves.
