Sequencing Choanoflagellates

Choanoflagellates, one-celled planktonic marine organisms, are aquatic microbes distinguished by a flagellum (green) used for swimming and feeding and surrounded by a collar of tentacles (red) against which bacterial prey are trapped. The nucleus of the one-celled organism is highlighted in blue. The newly sequenced genome of Monosiga brevicollis, a type of choanoflagellates, is already telling scientists about the evolutionary changes that accompanied the jump from one-celled life forms to multicellular animals like us.
