Ant genomes reveal how social insects evolved cooperation, preserved caste genes, and rewired chromosomes over 100 million ...

Mitochondria are the body's "energy factories," and their proper function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system acts like ...

4,500-year-old DNA offers new clues about ancient human societies.

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop.

When Charles Darwin first proposed how evolution works in 1859, it seemed plausible. Tiny changes stack up over time, ...

Researchers at the Francis Crick Institute and UCL have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread ...

When the DNA changes, the cell is able to make new proteins, sometimes with new functions, and in this way proteins are understood to be an integral part of evolution.

A team of researchers from University of Utah Health, University of Washington, PacBio, and other institutions has used multiple DNA sequencing technologies to develop the most comprehensive atlas yet ...

Consider the potential long-term effects on human evolution if our DNA suddenly stopped mutating. DC announces ‘extraordinary measures’ after House fails to pass budget fix Russian rouble ...

Evolution is a gradual change to the DNA of a species over many generations. It can occur by natural selection, when certain traits created by genetic mutations help an organism survive or reproduce.

A lost chapter in human evolution has been revealed after an analysis of modern DNA found that we come from not one but two ancestral populations—ones that drifted apart and later reconnected ...
