Researchers have shown that RNA droplets trap their own DNA templates, and that even low rates of mutation produce stable ...

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 evolutionary biologist Masatoshi Nei says Darwin never proved natural selection is the driving force of evolution — because it isn't. In a cavernous concert hall, before an eager audience of ...

Finding a place for "chance" in evolutionWhen we encounter the forms and mechanisms of living things, we ask, "What is the use of this?" Bird wings are useful for flying, and fish gills are useful for ...

A groundbreaking study published in PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more frequently where it ...

Numerical instability, the gain or loss of whole chromosomes, has received far less attention despite its frequency in ...

A population-scale genomic study of Neurospora crassa shows that the fungal defense mechanism RIP pervasively mutates single-copy functional genes, revealing an unexpected role in gene evolution.

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 ...
