"The combined Neoproterozoic
demosponge sterane record, showing 24-ipc and 26-mes steranes co-occurring in ancient rocks, is unlikely attributed to an isolated branch or extinct stem-group of
demosponges," Love said.
"Rather, the ability to make such unconventional steroids likely arose deep within the
demosponge phylogenetic tree but now encompasses a wide coverage of modern
demosponge groups," he said.
