The new tree of eukaryotes
For 15 years, the eukaryote Tree of Life (eToL) has been divided into five to eight major
groupings, known as 'supergroups'. However, the tree has been profoundly rearranged …

The origin and diversification of mitochondria
Mitochondria are best known for their role in the generation of ATP by aerobic respiration.
Yet, research in the past half century has shown that they perform a much larger suite of …

An excavate root for the eukaryote tree of life
C Al Jewari, SL Baldauf - Science Advances, 2023 - science.org
Much of the higher-order phylogeny of eukaryotes is well resolved, but the root remains
elusive. We assembled a dataset of 183 eukaryotic proteins of archaeal ancestry to test this …

[HTML][HTML] Genomics of new ciliate lineages provides insight into the evolution of obligate anaerobiosis
Oxygen plays a crucial role in energetic metabolism of most eukaryotes. Yet adaptations to
low-oxygen concentrations leading to anaerobiosis have independently arisen in many …

Anaerobic ciliates as a model group for studying symbioses in oxygen‐depleted environments
Anaerobiosis has independently evolved in multiple lineages of ciliates, allowing them to
colonize a variety of anoxic and oxygen‐depleted habitats. Anaerobic ciliates commonly …

Genomic analysis finds no evidence of canonical eukaryotic DNA processing complexes in a free-living protist
Cells replicate and segregate their DNA with precision. Previous studies showed that these
regulated cell-cycle processes were present in the last eukaryotic common ancestor and that …
