The classic methodology of inferring a phylogenetic tree from sequence data is composed of two steps. First, a multiple sequence alignment (MSA) is computed. Then, a tree is reconstructed assuming the ...

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 ...

The Mediterranean harbours the highest number of Hedera (Araliaceae) species, lineages, ploidy levels, and trichome morphologies of any area where the genus occurs. Previous molecular and cytogenetic ...

Tsukuba, Japan – Many people hate insects, but the iridescent colors and elegant flying style of dragonflies and damselflies have made them firm favorites worldwide. They have been around in some form ...

In phylogenetic analysis, branching diagrams are made to represent the evolutionary history or relationship between different species, organisms, or characteristics of an organism (genes, proteins, ...

The National Science Foundation has awarded two grants for a combined $1.5 million to Rice University computational biologist Luay Nakhleh to expand big data techniques in the fight against cancer and ...
