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 …

Knowing phylogenetic relationships among species is fundamental for many studies in
biology. An accurate phylogenetic tree underpins our understanding of the major transitions …

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 …

MicroRNAs (miRNAs) are∼ 22 nt RNAs that direct posttranscriptional repression of mRNA
targets in diverse eukaryotic lineages. In humans and other mammals, these small RNAs …

The tropics are the source of most biodiversity yet inadequate sampling obscures answers to
fundamental questions about how this diversity evolves. We leveraged samples assembled …

Molecular phylogeny indicates that metazoans (animals) emerged early in the
Neoproterozoic era, but physical evidence is lacking. The search for animal fossils from the …

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 …

Our understanding of phylogenetic relationships among bony fishes has been transformed
by analysis of a small number of genes, but uncertainty remains around critical nodes …

Over 600 million years ago, animals evolved from a unicellular or colonial organism whose
cell (s) captured bacteria with a collar complex, a flagellum surrounded by a microvillar …
