In real life, mutants can arise when their DNA changes to give them an advantage over the rest of the population. A team from ...

Ancient snakes once possessed four limbs, but evolution dramatically reshaped them. A genetic 'switch' called the ZRS ...

The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

Human cells usually contain two copies of most genes, one of which comes from the mother while the other comes from the father. It's long been thought that usually these two copies, or alleles of ...

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 ...

A study demonstrates that the 'previous state' of blood stem cells plays a decisive role in the subtype of leukemia that develops. The new technique, called STRACK, allows monitoring of the evolution ...

For most of human history, the mind was a mystery box. Behavior emerged, and we simply accepted it—strange, brilliant, troubled, gifted. But today, we peer inside that box. We map genes. We track ...

A phylogenetic tree of SARS-CoV-2 sequences, built with Nextstrain, displays sequences colored by their clade and organized by collection date. Over time, sequences mutate and diverge, forming new ...
