'Jumping genes' help stabilize DNA folding patterns

"Jumping genes"—bits of DNA that can move from one spot in the genome to another—are well-known for increasing genetic diversity over the long course of evolution. Now, new research at Washington University School of ...

'Living fossil' may upend basic tenet of evolutionary theory

The field of evolutionary biology has seen its share of spirited debates. But if there's one principle that virtually every expert in the field agrees on, it's that natural selection occurs at the level of the genome.

Evolution: A revelatory relationship

A new study of the ecology of an enigmatic group of novel unicellular organisms by scientists from Ludwig-Maximilians-Universitaet (LMU) in Munich supports the idea hydrogen played an important role in the evolution of Eukaryota, ...

Resurrected protein reveals structure of important enzyme

To disarm toxic substances, many organisms including humans possess enzymes called flavin-containing monooxygenases (FMOs). Despite their importance, the structure of the enzymes has not been resolved, as the protein is too ...

Self-restrained genes enable evolutionary novelty

Changes in the genes that control development can potentially make large contributions to evolution by generating new morphologies in plants and animals. However, because developmental genes frequently influence many different ...

A genetic tug-of-war between the sexes begets variation

In species with sexual reproduction, no two individuals are alike, and scientists have long struggled to understand why there is so much genetic variation. In a new study published in Nature Ecology & Evolution, a team of ...

New twist on CRISPR technology

In a classic episode of an old-school TV comedy called I Love Lucy, we see Lucille Ball stepping into an assembly line job at a candy factory. As the pace of the conveyor belt exceeds her ability to wrap the candy, the frenzy ...
