A new study theorizes that evolution ticks at different speeds, especially when a big group of organisms first appears.

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 ...

Molecular evolution investigates the processes that drive changes in genetic material over time. It encompasses the generation of mutations—whether through DNA replication errors, damage or other ...

People say “When pigs fly” to describe the impossible. But even if most mammals are landlubbers, the ability to glide or fly has evolved again and again during mammalian evolution, in species ranging ...

The list below offers a representative sample of the courses you can expect in the study of cellular and molecular biology at DePauw. From theoretical foundations to practical experiences, these ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

A reduced genome in an island species raises evolutionary questions.
