In biology, phylogenetic trees represent the evolutionary history and diversification of species -- the ''family tree'' of Life. Phylogenetic trees not only describe the evolution of a group of ...

What is macroevolution? Why is it important? How can macroevolutionary thinking help with interpreting patterns of primate evolution? Understanding macroevolution is important because it explains both ...

Using termite and cockroach genomes, researchers built phylogenetic trees from transposons, paving a new way to differentiate ...

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 ...

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 ...

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

American Journal of Botany, Vol. 88, No. 7 (Jul., 2001), pp. 1189-1198 (10 pages) Diversity in photosynthetic pathways in the angiosperm family Chenopodiaceae is expressed in both biochemical and ...

Birds are the only dinosaur lineage that survived until today. About 66 million years ago at the Cretaceous–Paleogene (K–Pg) boundary, a mass extinction event destroyed all non-avian dinosaurs, ...

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 ...

Evolution, Vol. 72, No. 5 (MAY 2018), pp. 1050-1062 (13 pages) Variation in rates of molecular evolution (heterotachy) is a common phenomenon among plants. Although multiple theoretical models have ...
