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 ...

(Memphis, Tenn.—July 28, 2023) The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children’s Research ...

Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

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 ...

For over a century, the reigning dogma in evolution has been that mutations — changes in the DNA — arise as blind accidents in the genome, leaving the survival of the fittest to separate the ...

Mutations, which occur continuously in every cell of our bodies, are a key contributor to cancer, ageing, and neurodegeneration. While exposure to mutagenic chemicals, or mistakes in cellular ...

How did horses become some of the greatest athletes in the animal kingdom? Researchers at Johns Hopkins Medicine may have found the answer, pinpointing a genetic mutation and evolutionary process that ...

The ability of organisms to generate adaptive genetic variation is crucial for evolutionary success, particularly in changing environments. The study investigates whether natural selection operates ...
