Monophyletic origins of the metazoa: an evolutionary link with fungi
TLDR
A phylogenetic framework inferred from comparisons of small subunit ribosomal RNA sequences describes the evolutionary origin and early branching patterns of the kingdom Animalia and shows the animal lineage is monophyletic and includes choanoflagellates.Abstract:
A phylogenetic framework inferred from comparisons of small subunit ribosomal RNA sequences describes the evolutionary origin and early branching patterns of the kingdom Animalia. Maximum likelihood analyses show the animal lineage is monophyletic and includes choanoflagellates. Within the metazoan assemblage, the divergence of sponges is followed by the Ctenophora, the Cnidaria plus the placozoan Trichoplax adhaerens, and finally by an unresolved polychotomy of bilateral animal phyla. From these data, it was inferred that animals and fungi share a unique evolutionary history and that their last common ancestor was a flagellated protist similar to extant choanoflagellates.read more

Selection of Conserved Blocks from Multiple Alignments for Their Use in Phylogenetic Analysis
TL;DR: A computerized method is presented that reduces to a certain extent the necessity of manually editing multiple alignments, makes the automation of phylogenetic analysis of large data sets feasible, and facilitates the reproduction of the final alignment by other researchers.

Parsimony jackknifing outperforms neighbor-joining
TL;DR: For analysis of large matrices, parsimony jackknifing is hundreds of thousands of times faster than extensive branch‐swapping, yet is better able to screen out poorly‐supported groups.

A revised six-kingdom system of life.
TL;DR: A revised six‐kingdom system of life is presented, down to the level of infraphylum, modified in the light of molecular phylogenetic evidence that Myxozoa are actually Animalia, not Protozoa, and that mesozoans are related to bilaterian animals.

Classification and evolution of P-loop GTPases and related ATPases.
TL;DR: In this article, the authors compared sequences and available structures for all the widely distributed representatives of the P-loop GTPases and GTPase-related proteins with the aim of constructing an evolutionary classification for this superclass of proteins and reconstructing the principal events in their evolution.

Kingdom protozoa and its 18 phyla.
TL;DR: The demarcation of protist kingdoms is reviewed, a complete revised classification down to the level of subclass is provided for the kingdoms Protozoa, ArchezoA, and Chromista, and the phylogenetic basis of the revised classification is outlined.

Evolutionary trees from DNA sequences: A maximum likelihood approach
TL;DR: A computationally feasible method for finding such maximum likelihood estimates is developed, and a computer program is available that allows the testing of hypotheses about the constancy of evolutionary rates by likelihood ratio tests.

TL;DR: A new method for estimating the variance of the difference between log likelihood of different tree topologies is developed by expressing it explicitly in order to evaluate the maximum likelihood branching order among Hominoidea.

The characterization of enzymatically amplified eukaryotic 16S-like rRNA-coding regions.
TL;DR: Oligodeoxynucleotides that are complementary to conserved regions at the 5' and 3' termini of eukaryotic 16S-like rRNAs were used to prime DNA synthesis in repetitive cycles of denaturation, reannealing, and DNA synthesis.
