Your DNA is constantly changing. And if it weren’t for genetic mutations, evolution wouldn’t exist. So, what would life be ...

Evidence of a newly identified mechanism of horizontal gene transfer raises important questions about how evolution works.

How do cells know what they should become as the body develops? Biological development depends crucially on spatial patterns: the lines that eventually give rise to segments, organs, or markings like ...

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 ...

Mutation dynamics in bacterial populations underpin the generation of genetic diversity that drives adaptation, speciation and the emergence of antimicrobial resistance. Spontaneous base substitutions ...

(Diane Isabel/iStock/Getty Images) The world's population is shifting. We're living longer than ever before, with elderly people taking up a greater proportion of the people on the planet. And yet ...

In the 1960s, Kimura’s neutral theory revolutionized molecular biology by arguing most DNA changes are random, not adaptive. A new study finds beneficial mutations are far more common than Kimura’s ...

As language models learn to interpret words in a sentence, protein language models learn how amino acids work together within a protein. Konstantina Tzavella, who used artificial intelligence in her ...
