For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

In biology you must have come across the two types of cells, the prokaryotic and eukaryotic cells. These two are the most ...

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 ...

The latest Virtual Issue from Genome Biology and Evolution highlights articles that provide new insight into the deep evolutionary relationships among extant organisms and the origin of eukaryotes ...

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, ...

Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...
