    Abstract: Small organisms (meiofauna) inhabiting sediments in the deepest ( 〉 10,000 m) ocean trenches are almost unknown. Through a quantitative study of live foraminifera from an extreme trench environment (10,900 m water depth), we demonstrate that these protists are an abundant meiofaunal component. Foraminifera are organisms of central importance in geology and biology. There is currently great interest in primitive noncalcareous taxa with simple, single-chambered shells. The Challenger Deep assemblages are dominated by these phylogenetically important forms. Molecular evidence suggests that similar taxa are modern representatives of the basal foraminiferal evolutionary radiation that probably occurred in the Precambrian (Neoproterozoic).

    Abstract: Fossil Foraminifera appear in the Early Cambrian, at about the same time as the first skeletonized metazoans. However, due to the inadequate preservation of early unilocular (single-chambered) foraminiferal tests and difficulties in their identification, the evolution of early foraminifers is poorly understood. By using molecular data from a wide range of extant naked and testate unilocular species, we demonstrate that a large radiation of nonfossilized unilocular Foraminifera preceded the diversification of multilocular lineages during the Carboniferous. Within this radiation, similar test morphologies and wall types developed several times independently. Our findings indicate that the early Foraminifera were an important component of Neoproterozoic protistan community, whose ecological complexity was probably much higher than has been generally accepted.
