Researchers investigate into the various lineages of Asgard archae, and determine one related to Hods as the ancestor of ...

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 ...

To carefully determine the phylogenetic position of the novel Asgard lineages in relation to other Archaea and to eukaryotes, we performed various in-depth phylogenomic analyses of concatenated rRNA ...

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 ...

The origin of organisms with complex cells, known as eukaryotes, is one of the most crucial parts of life’s evolutionary story. All animals, plants, and fungi are eukaryotes, and if complex cells had ...

Genome fragments are sometimes transferred from bacteria to eukaryotes via horizontal gene transfer (HGT). When these DNA fragments contain genes, these genes can retain their functionality in some ...

Mitochondria are membrane-bound components within cells that are often described as the cells' powerhouses. They've long been considered as essential components for life in eukaryotes, the group ...
