A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

(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 ...

In a recent study published in Nature Genetics, researchers performed an allelic-level single-cellular multi-omics evaluation of hematopoietic stem/progenitor cells (HSPCs) obtained from individuals ...

The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children's Research Hospital have added a new layer of ...

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 ...

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 ...

The genome sequences of millions of individual SARS-CoV-2 viruses have enabled researchers to study evolution in a way that wasn’t possible before. The coronavirus’s global proliferation means that we ...

A research team has discovered the key role that the APOBEC3A and APOBEC3B enzymes play in driving cancer mutations by modifying the DNA in tumor genomes, offering potential new targets for ...

All of living nature is subject to evolution. Living organisms are exposed to selection pressure, which means that those that are best able to assert themselves survive. This natural selection process ...
