Now, researchers have presented a new analysis of the patterns generated by phylogenetic trees, suggesting that they reflect previously hypothesized connections between evolution and ecology.

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 analysis underpins modern evolutionary biology by constructing trees that illustrate the relationships among species and genes. Gene tree reconciliation extends these analyses by ...

In the phylogenetic approach, information is extracted from evolutionary relationships between existing species, using mostly genetic data, and structured in phylogenetic trees known as timetrees.

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 ...

Genomic analysis leverages computational tools to resolve previously indistinct branches of the avian family tree.

There are various methods for producing a rooted phylogenetic tree but the most common utilize an outgroup consisting of a distant relative for all other species within the analysis.

Dr Sebastian Maurer-Stroh, executive director of the Bioinformatics Institute at A*Star, said a phylogenetic or "family" tree is created using viral mutations as markers to compare the virus genomes.

An analysis of millions of SARS-CoV-2 genomes finds that recombination of the virus is uncommon, but when it occurs, it is most often in the spike protein region, the area which allows the virus ...
