The very nature of the evolutionary history of organisms and the limitations of current phylogenetic reconstruction methods mean that part of the tree of life might prove difficult, if not ...

A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.

Evolutionary tree of life for mammals greatly improved Date: September 23, 2011 Source: University of California - Riverside Summary: Biologists have released a large and robust DNA matrix that ...

This phylogenetic tree, built from genetic sequencing and fossil data, helps explain the relationships between different kinds of insects across millions of years of evolution.

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

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 understanding that gene trees are often in discord with each other and with the species trees that contain them has led researchers to methods that incorporate the inherent stochasticity of ...
