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 ...

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.

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

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.

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.

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

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 ...

But the biggest rebuttal comes in the form of a phylogenetic analysis. This involves figuring out where a species belongs in the evolutionary tree, based on the traits it shares with related ...

“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 ...

The broken-wing display, in which birds fake being wounded to protect their nests from predators, is found across the avian phylogenetic tree, a study finds. Now that it had an audience, the killdeer ...
