All life on Earth comes from one single ancestor. And it's so much older than we thought. All life on Earth can be traced ...

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important for ...

Deep in hydrothermal vents beneath the Arctic Ocean, scientists have discovered an organism that sheds fresh light on the evolutionary link between simple and complex cellular life. The microbe and ...

A nucleus is one of many membrane-bound compartments that distinguishes our eukaryotic cells from the prokaryotic cells of microorganisms like bacteria. Eukaryotic cells also possess energy-producing ...

Norman Pace has a problem with prokaryotes. It’s not that Pace has anything against the organisms themselves. The microbiologist and RNA scientist from the University of Colorado at Boulder has made a ...
