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 ...
A new computational tool improves the analysis of genetic data, making it easier and faster to study the evolutionary relationships between species.
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.
“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 ...
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 researchers assessed phylogenetic signal in different taxonomic (e.g., angiosperms and gymnosperms) and ecological (e.g., tropical, temperate, and boreal) groups of tree species, explored the ...
