F. Archaea and the prokaryote-to-eukaryote transition. Microbiology and Molecular Biology Reviews 61, 456–502 (1997) Doolittle, W. F. & Bapteste, E. Pattern pluralism and the Tree of Life ...

Eukaryogenesis occurred suddenly, driven by the growing length of genes and the limitations on producing longer proteins. An international team of four senior scientists from Mainz, Valencia, Madrid, ...

The question of where exactly eukaryotes branch on the tree of life has been debated by scientists for decades. But the discovery of the Asgard archaea—the closest prokaryotic relatives to modern ...

It is best considered a member of a previously undescribed, entirely extinct group of eukaryotes,” the team wrote in the study paper. This challenges our understanding of the tree of life itself.

These functional types do not correspond to natural groups, because they occur in an interleaved manner across the tree of eukaryotic life. Instead they correspond to ecological specializations.

Furthermore, they discovered a scaling-invariant mechanism of gene growth across the entire tree of life ... length stabilizes after the onset of the eukaryotic cell at about 500 amino acids ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

Work in the Katz lab aims to elucidate principles of eukaryotic evolution through phylogenetic reconstruction, community sampling and analyses of genome evolution. The bulk of eukaryotic diversity is ...
