Genome-scale data and the development of novel statistical phylogenetic approaches have
greatly aided the reconstruction of a broad sketch of the tree of life and resolved many of its …

Cell types are the basic building blocks of multicellular organisms and are extensively
diversified in animals. Despite recent advances in characterizing cell types, classification …

A central question in evolutionary biology is whether sponges or ctenophores (comb jellies)
are the sister group to all other animals. These alternative phylogenetic hypotheses imply …

Artificial intelligence-based protein structure prediction methods such as AlphaFold have
revolutionized structural biology. The accuracies of these predictions vary, however, and …

Animal genomes show networks of deeply conserved gene linkages whose phylogenetic
scope and chromosomal context remain unclear. Here, we report chromosome-scale …

Rapid growth of genome data provides opportunities for updating microbial evolutionary
relationships, but this is challenged by the discordant evolution of individual genes. Here we …

Proper biological interpretation of a phylogeny can sometimes hinge on the placement of
key taxa—or fail when such key taxa are not sampled. In this light, we here present the first …

A classification of the entire Phylum Nematoda is presented, based on current molecular,
developmental and morphological evidence. The classification reflects the evolutionary …

In phylogenomics the analysis of concatenated gene alignments, the so-called supermatrix,
is commonly accompanied by the assumption of partition models. Under such models each …

Parasitic nematodes (roundworms) and platyhelminths (flatworms) cause debilitating
chronic infections of humans and animals, decimate crop production and are a major …
