What do phylogenetic trees illustrate? These diagrams don't just organize knowledge of biodiversity - they also show us that living species are the summation of their evolutionary history.

This may be the reason why biologists have only in the last few decades come to develop a rigorous understanding of phylogenetic trees. This understanding allows present-day researchers to use ...

The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a study in Nature Communications. It is the first time ...

Bacterial DNA isolated from a 120-year-old preserved plant cutting helped reconstruct the history of Pierce’s disease in ...

Evolutionary relationships, or phylogeny, involves studying evolutionary paths or lineages of organisms and is often represented by a phylogenetic tree. A phylogenetic tree shows the points at which ...

The Evolution Lab contains two main parts: Build A Tree: Students build phylogenetic trees themed around the evidence of evolution, including fossils, biogeography, and similarities in DNA.

A new computational tool improves the analysis of genetic data, making it easier and faster to study the evolutionary relationships between species.

“Understanding phylogenetic trees can be difficult, but we’re working to make it more accessible,” says principal investigator Chia Shen, director of Scientists’ Discovery Room (S ...

By analyzing these similarities and differences in the DNA, we can generate a hypothetical evolutionary tree, called a phylogenetic tree, that estimates, to the best of our ability, what the actual ...

Such a phylogenetic tree would use molecular sequence data to tell us both when each species or group of species first appeared, and which other groups on the tree are their closest relatives.

MAFFT performs multiple sequence alignment for each gene across all the genomes - Concatenates the alignments - Filters positions from the multiple alignment that show variations across the genomes - ...
