Gene tree and species tree reconciliation is a crucial area of study in evolutionary biology that seeks to understand the relationships between gene evolution and species evolution. This process ...

The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, ...

Two fundamental mechanisms of gene regulation involve transcription factors and microRNAs, a large class of small, non-coding RNAs. It is widely believed that phenotypic evolution is closely ...

Researchers have innovatively merged protein structural data with genetic sequences to construct evolutionary trees, ...

The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a new study. It is the first time researchers use data from ...

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

In a new study involving whole-genome data, researchers present “CASTER,” a tool that uses arrangements in DNA sequences known as site patterns to infer “species trees,” which are diagrams that depict ...

Evolutionary trees show how different species have evolved ... There's some reason why that lengthened middle finger meant that that gene was more likely to be passed to the next generation ...

Gene duplication is very important for the evolution of species because it can facilitate the creation of new genes. Normally, changes to genes result in loss of function and so are weeded out by ...

Researchers say strategy will help understand the history of life, monitor the spread of pathogens or create new treatments for disease.

There were so many instances of gene transfer between different giraffe lineages that the evolutionary history of giraffes appears more like a “reticulated” network than a tree-like structure.
