Researchers have recovered and sequenced Mycobacterium lepromatosis genomes from 4,000-year-old human remains in Chile, providing the first molecular evidence of ancient leprosy in the Americas. The ...

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 ...

Buddhist temples in China are home to trees from dozens of endangered species, a new study shows. Some of them are almost 2,000 years old.

Our tree estimates positions Lepisosteiformes (i.e., gars) as the sister group to Teleostei, with the clade Euteleostei as the sister group to Elopiformes (Anguillidae, Megalopidae), Osteoglossiformes ...

Relatively few genes have evolved vertically from the last universal common ancestor to modern prokaryotes, and phylogenetic analysis of these genes demonstrates a great genetic distance between ...

The research also helps to fit the members of the PENA clade into a phylogenetic tree, which enables ongoing research on the plants by increasing understanding of how the different species are ...

Phylogenetic analyses reveal the evolutionary derivation of species. A phylogenetic tree can be inferred from multiple sequence alignments of proteins or genes. The alignment of whole genome sequences ...

The easiest way to overcome the problem is to simply use net speciation events along a lineage as a measure of net diversification instead of clade size. Uncertainty in the number of net speciation ...

We performed phylogenetic analyses of 81 plastid genes in 64 sequenced genomes, including 13 new genomes, to estimate relationships among the major angiosperm clades, and the resulting trees are used ...
