Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning “true kernel”) have a cell nucleus that harbours most of the cell’s genetic information and ...

Prokaryotes are ancient, simple forms of life that include bacteria and archaea. These cellular life forms lack membrane-bound organelles. Those organelles, which include the nucleus and the ...

For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first ...

In a study published in Science Advances on Jan. 24, researchers led by Prof. ZHU Maoyan from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences reported their ...

Eukaryotic plankton are an essential and highly diverse component of marine ecosystems. A research team has established their global geographic distribution using DNA data and a probabilistic model.
