In a deft experiment, biologists have recreated a system that could have birthed essential cell features such as mitochondria ...

He sees the predatory planctomycetes as the microbial Archaeopteryx, a bridge organism between the prokaryotes and eukaryotes, and is convinced that the planctomycetes played a role in eukaryogenesis, ...

What took so long for humans to appear on Earth? The Earth is 4.6 billion years old, and life began about 4 billion years ago ...

On one side there are the tiny bacteria and archaea, collectively known as prokaryotes. On the other side there are the huge and unwieldy eukaryotes, the third great domain of life. A typical ...

Vast numbers of different prokaryotic microorganisms shape the biosphere, with diverse metabolic capabilities. Determination of genome sequences for a wide range of bacteria and archaea now requires ...

Living organisms are made up of two kinds of cells—prokaryotes and eukaryotes. Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles within the cell ...
