Extant anaerobic eukaryotes are morphologically, physiologically and phylogenetically diverse. This is in part because of their multiple independent evolutionary origins. Some are facultatively ...

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, ...

Ancient Australian fossils indicate that the earliest eukaryotes depended on oxygen, providing new evidence that oxygen ...

All cells in animals, plants, fungi, and protists share a fundamental characteristic: they are eukaryotic cells—complex cells ...

All complex life forms on Earth, including plants and animals, are made up of eukaryotic cells; they are more sophisticated than bacterial or archaeal cells, which are prokaryotic. Eukaryotes have ...

A lot happened in the hundreds of millions years separating the first and last eukaryotic common ancestors, but when and how most features arose remains a mystery. Eukaryogenesis is broadly defined as ...

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 ...

The team used the computing power of the MareNostrum series of supercomputers to analyze public genomic data spanning biodiversity as a whole.

In a new study published in Nature, Dr. Toni Gabaldón and his team used the MareNostrum supercomputer to reconstruct the genetic origin of the last common ancestor of all eukaryotes - the cellular ...

Modern eukaryotic cells have proteins that enable chromosome segregation during cell division, new discoveries shed light on their origin in simpler prokaryotic organisms. Modern nucleated (eukaryotic ...
