Genome of marine organism tells of humans' unicellular ancestors

Berkeley -- The newly sequenced genome of a one-celled, planktonic marine organism, reported today (Thursday, Feb. 14) in the journal Nature, is already telling scientists about the evolutionary changes that accompanied the jump from one-celled life forms to multicellular animals like ourselves. ...
