For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

Scientists from the Broad Institute of MIT and Harvard in Cambridge, Massachusetts, have identified novel mutations in bacteria that promote the evolution of high-level antibiotic resistance. The ...

A new wave of scientists argues that mainstream evolutionary theory needs an urgent overhaul. Their opponents have dismissed them as misguided careerists – and the conflict may determine the future of ...

A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...

Mitochondria are known as the body’s “energy factories,” and their function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system ...

Centralized migration accelerates adaptation and drives parallel evolution, emphasizing the key influence of spatial organization on evolutionary dynamics across systems from pathogen transmission to ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed ...

Rachel Robson, assistant professor of biology at Morningside College, and Susan Burns, associate dean for academic affairs, collaborated on an article that was published in the May issue of the ...

Some 17 months ago, scientists detected an outbreak of highly pathogenic H5N1 avian influenza in dairy cattle in Nebraska in ...
