A team of biologists report in this week's Nature the genome sequences of three organisms that represent more than one-quarter of marine species, including clams, octopuses and the segmented worms, ...

Biology professor Kevin Peterson, working with researchers from several institutions, has developed a breakthrough technique to study the evolutionary relationships between species. His research, ...

The eerie painting depicts an image few of us would want to see in the mirror, let alone casting a shadow across our own field of vision: a pale, segmented worm slithering across an unblinking eyeball ...

Scientists say Tully Monster was not a segmented worm or a free-swimming slug, as once hypothesized, but rather a type of jawless fish called a lamprey Primer is Mint's signature mode of explaining a ...
