Gene duplication events in European eels have restored cell membrane permeability for urea and boric acid through mutated aquaporin genes. “The aromatic/arginine (ar/R) selectivity filter is a narrow ...

When cells divide and chromosomes are replicated for the daughter cells in a select type of cell called the germline, which is happening constantly in living things, sometimes things don’t go ...

A new study reveals how the duplication of the salivary amylase gene may not only have helped shape human adaptation to starchy foods, but may have occurred as far back as more than 800,000 years ago, ...

Phylogenetic analysis underpins modern evolutionary biology by constructing trees that illustrate the relationships among species and genes. Gene tree reconciliation extends these analyses by aligning ...

Gene tree and species tree reconciliation is a pivotal framework in evolutionary biology that bridges the evolutionary histories of individual gene families with the broader context of species ...

Data from a new study links a pair of duplicated genes to human brain features. The research provides a roadmap for scientists to gain a deeper understanding of brain function and evolution, as well ...

Evolution is traditionally associated with a process of increasing complexity and gaining new genes. However, the explosion of the genomic era shows that gene loss and simplification is a much more ...

A team led by University of Pittsburgh School of Public Health geneticists has shown, for the first time, that a gene “silencer” that resides in junk DNA is directly sparing people from a devastating ...

Approximately four billion years ago, the first forms of life emerged on Earth. For eons, biological life consisted of prokaryotic organisms, either early bacteria or archaea. Determining when ...
