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 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 ...

"I would say that any modern biologist would, or should, say that birds are reptiles," Martin Stervander, an evolutionary ...

These phylogenetic or evolutionary trees are traditionally built by comparing DNA or protein sequences and counting the similarities and differences to infer relationships. However, researchers ...

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 ...
