The Archaea was recognized as a third domain of life 40 years ago. Molecular evidence soon suggested that the Eukarya represented a sister group to the Archaea or that eukaryotes descended from ...
When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors billions of years ago. According to new research from ...
Eukaryotes—fungi, plants, us—are complex. Our large cells are characterized by their different compartments, many of which are neatly enclosed within a boundary of membrane. These compartments contain ...
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 new idea about the origin of complex life turns current theories inside out. Scientists explain their 'inside-out' theory of how eukaryotic cells, which all multicellular life -- including us -- are ...

Scientists in Australia have discovered a tiny microbe that could reveal the origin of human life
Scientists have discovered an archaea called ‘Asgard’ in the extremely high-salinity waters of Shark Bay, Australia, which ...
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 ...
In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the ...
Before 1977 life came in two fundamental flavors: bacteria and the rest of us. The bacteria, also known as prokaryotes, had DNA that floated free in the cell, whereas the eukaryotes--such as fungi, ...
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 ...
