Phylogeny is the representation of the evolutionary history and relationships between groups of organisms. The results are represented in a phylogenetic tree that provides a visual output of ...

In biology, phylogenetic trees represent the evolutionary history and diversification of species -- the "family tree" of Life. Phylogenetic trees not only describe the evolution of a group of ...

The tool, called PsiPartition, improves both the computational efficiency of the data analysis and the accuracy of the phylogenetic trees that visualize these relationships.

Phylogenetic analysis of DNA or other data commonly gives rise to a collection or sample of inferred evolutionary trees. Principal Components Analysis (PCA) cannot be applied directly to collections ...

Phylogenetic tree reconstruction is difficult in the presence of lateral gene transfer and other processes generating conflicting signals. We develop a new approach to this problem using ideas ...

The new model focuses on phylogenetic diversity, which is very different from counting species, today's standard measure of biodiversity. The same number of species (three blue circles) can have a ...

Phylogenetic inference is a computationally demanding task, given the large number of trees that are possible — the 'tree space' — even when a relatively small number of species is considered.

This month, George Tiley began his NC State appointment as an assistant professor of plant and microbial biology. Right ...

Yet, most published trees are not archived, and there is no community standard governing the recommended format or content to ensure a re-usable phylogenetic record.

Scientists have published the largest nematode phylogenetic tree up until now. It contains over 1,200 species and is entirely based on the analysis of DNA sequence data.

The resulting phylogenetic estimate offers novel insights into the rapid radiation of modern birds and provides a taxon-rich backbone tree for future comparative studies.” ...

The development of reliable phylogenetic trees is an important step in characterising new pathogens and developing new treatments in biomedicine.
