A high-resolution analysis of the global diversity of fossils spanning 2 billion years shows how a series of super ice ages ...

The findings show that Earth's severe Cryogenian glaciations catalyzed a pivotal shift in the evolution and diversity of ...

If all the world's a stage and all the species merely players, then their exits and entrances can be found in the rock record ...

Planctomycetes Are Important for Theories of the Origin of Eukaryotes and Their Nuclei Why are planctomycetes important for understanding evolution of eukaryotes? There are two major types of ...

Advanced tools and expanded fossil datasets have painted a clearer picture of the eukaryotic diversity of the Proterozoic eon, which has been hard to quantify. The findings show that Earth's severe ...

Archaea, a domain of life distinct from bacteria and eukaryotes, are known for thriving in extreme environments such as hot ...

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed. Various ...

Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but ...

By establishing the biggest paleobiology database of early Earth to date and employing cutting-edge analytical tools, ...

SA2, encodes one of the proteins needed to make ribosomes, the central engines in all cells that translate genetic information into proteins, the building blocks of life. This is the first eukaryotic ...

Eukaryotes, on the other hand, utilize the Kozak sequence to start translation. The Kozak sequence surrounds the start codon (AUG) and has a consensus sequence of (GCC)GCCRCCAUGG, where R ...
