Abstract
It is generally assumed that the first fossil appearance of a group of organisms corresponds to its evolutionary origin. But we have molecular evidence that extant members of the most abundant microfossil-forming group, the Foraminifera, include ‘naked’ amoeboid species, indicating that ancestral foraminiferans could be unfossilized. This means that the origin of the group might be much earlier than has been deduced from the fossil record. This might help to explain the conflicting molecular and fossil data on the origin of the Foraminifera. © 1999 Macmillan Publishers Ltd.
