Finally, the three-domain structure of Woese's tree (Figure 1a) shows that evolutionary history is decoupled from biological organization. Indeed, archaea and bacteria appear very similar ...

As a result, some evolutionary biologists squabble about whether the evolutionary relationships among living organisms are best described by the Darwinian tree-of-life metaphor ... bacteria-like ...

Tree of life with one branch fewer In recent years, researchers have found growing indications of close links between Asgard archaea and eukaryotes and ... the cytoskeleton was an important step in ...

the billions of years that have passed since the fusion of an archaea and a bacteria have resulted in a lack of evolutionary intermediates in the phylogenetic tree until the emergence of the ...

Most of the details of these evolutionary leaps ... tree in which eukaryotes are a distinct lineage and toward a two-domain tree, in which eukaryotes emerged from within the archaea as a secondary ...

Archaea—one of the three primary domains ... their genetic makeup has long suggested a closer evolutionary relationship with eukaryotes, the domain encompassing plants and animals.

A Two-Branch Tree of Life? Mounting evidence now suggests that eukaryotes may have evolved from Asgard archaea ... that it played a key role in the evolution of eukaryotic cells.

“This is the most exciting and important paper on big questions about eukaryotic origins and the tree of life in years,” said evolutionary biologist Jeffrey ... the phylogenetic tree of life: bacteria ...

In eukaryotes, microtubules are responsible for transport processes within the cell, and in Asgard archaea, they may have played a key role in the evolution of these microorganisms. In their study ...

An international collaboration between four scientists from Mainz, Valencia, Madrid, and Zurich has published new research in the Proceedings of the National Academy of Sciences, shedding light on the ...
