Vessels in a tree’s xylem transport water from the roots to the rest of the plant. Hardwood tree species tend to have large ...

One study is of enamel proteins from extinct mammal fossils from the Turkana Basin in Kenya, and the other study is of enamel proteins from extinct mammals in the Haughton impact crater site located ...

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

Alignment and sequencing errors are a major concern in molecular evolution, and this valuable study represents a welcome improvement for genome-wide scans of positive selection. This new method seems ...

Rooted phylogenetic networks are used to describe evolutionary histories that contain non-treelike evolutionary events such as hybridization and horizontal gene transfer. In some cases, such histories ...

That may come as no surprise, given that birds are dinosaurs. But in terms of classification, this raises a question: Since ...

T-REX was created in response to requests to be able to easily link phylogenetic and phenotypic information together and yield insights from this. This package consists of a GUI-enabled phylogenetic ...

A bizarre ancient fish has scientists stumped as a new review of two fossils says all theories to date of what it might be are probably wrong. The preprint paper, which hasn’t yet undergone peer ...

Much evidence from biological theory and empirical data indicates that, gene trees, phylogenetic trees reconstructed from different genes (loci), do not have to have exactly the same tree topologies.

A groundbreaking study employing full genome-scale data has revolutionized our understanding of bird evolution, revealing new insights into the phylogenetic relationships among bird species. By ...

The resulting phylogenetic estimate offers novel insights into the rapid radiation of modern birds and provides a taxon-rich backbone tree for future comparative studies.” ...
