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

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

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 ...

If you still remember that "Dear King Phillip Came Over For Good Spaghetti," you'll likely also recall the corresponding taxonomic ranks of biology: domain, kingdom, phylum, class, order, family, ...

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 ...

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 ...

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 ...
