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.

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.

“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 ...

Researchers at Hokkaido University have developed a new computational tool to help evolutionary biologists analyze complex genetic data to reconstruct the evolutionary history of species and the ...

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 ...
