Directed evolution is a laboratory method that speeds up protein mutations to help create novel cancer and neurodegenerative disorder therapies. In a new study, scientists detail a method called ...

The movement of genetic material between organisms that aren't directly related is a significant driver of evolution, especially among single-celled organisms like bacteria and archaea. A team led by ...

When scientists want to create a protein that can potentially treat disease, one approach is to begin with a different protein and evolve it in the lab, selecting over many generations for versions ...

Why does natural selection appear to happen slowly on long timescales and quickly on short ones? A multigenerational study of four lizard species addresses biology’s “paradox of stasis.” James Stroud ...

No and yes. Natural selection is a rigorous testing process that filters out what works from what doesn’t, driving organisms to evolve in particular directions. However, chance events play a big role ...
