Single-gene trees have failed to locate the root of the eukaryote tree because of systematic biases in sequence evolution. Structural genetic data should yield more reliable insights into deep phylogenetic relationships. We searched major protist groups for the presence or absence of a gene fusion in order to locate the root of the eukaryote tree. In striking contrast to previous molecular studies, we show that all eukaryote groups ancestrally with two cilia (bikonts) are evolutionarily derived… 
The eukaryotic tree of life from a global phylogenomic perspective.

The pros and cons of phylogenomics are discussed and the eukaryotic supergroups are reviewed in light of earlier work that laid the foundation for the current view of the tree, including the position of the root.
Root of the Eukaryota tree as inferred from combined maximum likelihood analyses of multiple molecular sequence data.
Combined maximum likelihood analyses of 22 protein-coding genes including the above four genes clearly demonstrated that Diplomonadida and Parabasala shared a common ancestor in the rooted tree of Eukaryota, but only when the fast-evolving sites were excluded from the original data sets.
Rooting the eukaryotic tree with mitochondrial and bacterial proteins.
A new approach to the rooting of the eukaryotic tree is applied by using a subset of genomic information with more recent evolutionary origin-mitochondrial sequences, whose closest relatives are α-Proteobacteria.

A complex and punctate distribution of three eukaryotic genes derived by lateral gene transfer
It is shown that several apparently simple cases of lateral transfer are actually more complex than they originally appeared: in these instances two or more distantly related eukaryotic groups share the same bacterial gene, resulting in a punctate distribution.
Phylogenomics and the reconstruction of the tree of life
This work has demonstrated the power of the phylogenomics approach, which has the potential to provide answers to several fundamental evolutionary questions, but challenges for the future have also been revealed.
Collodictyon—An Ancient Lineage in the Tree of Eukaryotes
This work investigates the evolutionary origin of the poorly studied protist Collodictyon by sequencing a cDNA library as well as the 18S and 28S ribosomal DNA (rDNA) genes, and suggests that it constitutes a new lineage in the global eukaryote phylogeny.
Phylogeny of Opisthokonta and the evolution of multicellularity and complexity in Fungi and Metazoa
New sequence data indicate that choanoflagellates are a monophyletic rather than a paraphyletic assemblage that independently gave rise to animals and fungi as suggested by some authors and the nucleariid filose amoebae are the likely sister group to Fungi.


Phylogeny: Parabasalian flagellates are ancient eukaryotes
The structure of the gene encoding enolase, an enzyme of the glycolytic pathway, is investigated and it is found that the gene from parabasalian flagellates lacks two deletions present in other eukaryotic enolases, indicating that Parabasalia could be the most ancient eUKaryotes examined so far.
Early branching eukaryotes?
A kingdom-level phylogeny of eukaryotes based on combined protein data.
The sequences of four of the most broadly taxonomically sampled proteins available are combined to create a roughly parallel data set to that of SSU rRNA, showing strong support for most major groups and several major supergroups.
Reconstructing Early Events in Eukaryotic Evolution

Investigation of the nuclear genomes of entamoebae, Microsporidia, parabasalids, and diplomonads suggests that these organisms likely descend from mitochondrion‐bearing ancestors, and most evidence suggests that the mitochondrial endosymbiosis took place prior to the divergence of all extant eukaryotes.
A Search for the Origins of Animals and Fungi: Comparing and Combining Molecular Data
Neither the monophyly of the slime molds nor their close relationship to animals and fungi are consistently supported by ribosomal RNA data, so it appears unlikely that any single molecule will accurately reconstruct all higher‐order taxonomy.
Retortamonad flagellates are closely related to diplomonads--implications for the history of mitochondrial function in eukaryote evolution.
The robust phylogenetic association between diplomonad and retortamonads suggests that they share an amitochondriate ancestor, and strong evidence indicates that diplomonads have secondarily lost their mitochondria.
Early–branching or fast–evolving eukaryotes? An answer based on slowly evolving positions

The analysis of slow–evolving positions, carried out with the newly developed slow–fast method, reveals that these lineages are misplaced at the base of the tree by a long branch attraction artefact, consistent with the Big Bang hypothesis that all extant eukaryotic lineage are the result of multiple cladogeneses within a relatively brief period.
The analysis of 100 genes supports the grouping of three highly divergent amoebae: Dictyostelium, Entamoeba, and Mastigamoeba
The phylogenetic relationships of amoebae are poorly resolved. To address this difficult question, we have sequenced 1,280 expressed sequence tags from Mastigamoeba balamuthi and assembled a large
An ancestral mitochondrial DNA resembling a eubacterial genome in miniature
Feature of gene content together with eubacterial characteristics of genome organization and expression not found before in mitochondrial genomes indicate that R. americana mtDNA more closely resembles the ancestral proto-mitochondrial genome than any other mtDNA investigated to date.
