A new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on earth, ...

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 ...

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 ...

Despite recent advances in the study of eukaryogenesis, much remains unresolved about the origin and evolution of the most complex domain of life. This year, University of Paris-Saclay biologist ...

Unlike prokaryotic cells, all eukaryotic cells have nuclei. Nuclei house most of a cell’s genetic information – much of it in the form of DNA – making a nucleus a sort of blueprint for building future ...

Allan Albig receives funding from the National Institute of Health. Think back to that basic biology class you took in high school. You probably learned about organelles, those little “organs” inside ...
