Eukaryotes—the building blocks of complex life—appeared on Earth 1.7 billion years ago, and now scientists have solved a ...

Led by Jizhong Zhou, Ph.D., the director of the Institute for Environmental Genomics at the University of Oklahoma, an international research team conducted a long term experiment that found that ...

For decades, scientists have believed that complex life began when two very different microbes joined forces, eventually giving rise to plants, animals, and fungi. But one major puzzle remained: how ...

Archaea—one of the three primary domains of life alongside bacteria and eukaryotes—are often overlooked and sometimes mistaken for bacteria due to their single-celled nature and lack of a nucleus. Yet ...

In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...

In a scientific twist that blends cutting-edge genomics with Norse mythology, researchers have identified the closest microbial relatives of all complex life on Earth, including humans. The discovery ...

Archaea are a relatively recently discovered group of microorganisms that occupy their own branch on the tree of life. Though similar in some ways to bacteria, they are not the same. Researchers have ...
