This enabled the researchers to compare ancient bacterial genomes with modern strains, creating a comprehensive phylogenetic ...

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 ...

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 ...

Proteins degrade over time, making their history hard to study. But new research has uncovered ancient proteins in the enamel ...

It has genes for ribosomes, tRNAs, and mRNAs. These components are the scaffolding of life: the tools by which cells read ...

Researchers have presented a new analysis of the patterns generated by phylogenetic trees, suggesting that they reflect previously hypothesized connections between evolution and ecology.

South Africa has one of the world's richest fossil records of hominins (humans and their fossil ancestors). But many ...

Scientists have published the largest nematode phylogenetic tree up until now. It contains over 1,200 species and is entirely based on the analysis of DNA sequence data.

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 ...

Based on the results of the new algorithm, scientists can select only the most informative genes to build phylogenetic trees, an approach that could make the process more accurate and efficient.

Researchers once used just one gene or a handful to compare organisms. But the last decade has seen an explosion in phylogenetic data, rapidly inflating the data pool for generating these trees. These ...
