Tree performance is generally considered as the consequence of the interplay between ecological and evolutionary processes. However, the differential effect among species and the portion of those ...

The new model focuses on phylogenetic diversity, which is very different from counting species, today's standard measure of biodiversity. The same number of species (three blue circles) can have a ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...

Biologists will be able to reconstruct the process of evolution, determine relationships between species and build phylogenetic trees with greater accuracy thanks to a new method for identifying ...

New research headed by scientists at the Centre for Genomic Regulation (CRG) has demonstrated how the three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary ...

There are so many more questions we have yet to answer in Zoology so grab some fossils, fire up the DNA sequences, and bring your best hypothesis as we try to figure out where all the baby eels are, ...

As of June 16, 2022, there were 10,594,265 sequences displayed in the UShER COVID-19 phylogenetic tree. 10 million sequences of COVID-19’s genomic code have now been organized into a phylogenetic tree ...
