Revisiting metazoan phylogeny with genomic sampling of all …
From these, we constructed 5578 maximum-likelihood (ML) gene family trees from a subset of well-aligned groups, and processed these to mask candidate redundant isoforms, remove isolated divergent sequences and further split trees into subfamilies subtended by long internal branches .
we explore the current consensus in metazoan phylogeny (summarized in Fig. 1), and discuss our present knowledge in relation to morphological and developmental character evolution. We also appraise the merits and limitations of several alternative molecular phylogenetic approaches that are currently used to address the vexing question of
Metazoan Phylogeny and Evolution | Giribet Lab - Harvard …
Metazoan Phylogeny and Evolution. A major goal of the Giribet Lab is to elucidate the relationships among the higher metazoan lineages (phyla, classes, etc.). We are currently generating and analyzing large phylogenomic data sets to resolve the Animal Tree of Life.

The phylogenetic tree shows that the presence of ETs is not a shared characteristic and that there is no congruence with the phylogenetic history of the groups, since the presence of ETs is...
2017年5月8日 · use dozens of phylogenetic markers, have shown that the clade formed by C. limacisporum plus Ichthyosporea is the earliest-branching holozoan lineage, and that
Gene gain and loss across the metazoan tree of life
2020年1月28日 · A phylogenomic approach to gene repertoire evolution across the metazoan tree of life reveals unbalanced distributions of gene gains, losses and duplications
A Phylogenomic Investigation into the Origin of Metazoa - Oxford …
2008年1月9日 · By phylogenomic analyses of genes encoded in nuclear and mitochondrial genomes, we show that the choanoflagellates are the closest relatives of the Metazoa, followed by the Capsaspora and Ichthyosporea lineages, although the branching order between the latter 2 groups remains unclear.
Cleavage patterns and the topology of the metazoan tree of life
1997年7月22日 · A phylogenetic hypothesis of some metazoan phyla based on major groupings suggested by SSU rRNA data, modified so as to produce a parsimonious distribution of cleavage types.
Deep metazoan phylogeny: When different genes tell different …
2013年4月1日 · To unravel the causes for the patterns of extreme inconsistencies at the base of the metazoan tree of life, we constructed a novel supermatrix containing 122 genes, enriched with non-bilaterian taxa. Comparative analyses of this supermatrix and its two non-overlapping multi-gene partitions (including ribosomal and non-ribosomal genes) revealed ...
