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 ...

The analysis revealed that about 2 per cent of sperm from men in their early 30s contained disease-causing mutations. That ...

(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 ...

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 ...

These sequences are extremely prone to mutations and rank among the most functionally important regions in the entire human ...

Geneticists have sought to understand the impact of genetic mutations, and what drives and maintains changes in DNA. Researchers have now reconstructed the evolution of a set of genes, and the ...

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 ...

In a recent study published in the bioRxiv* preprint server, researchers analyzed the characteristics of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Omicron subvariants BA.4, BA.5, ...

Discover interesting facts about how evolution works, the different patterns that can emerge from evolution, how quickly organisms can evolve, and whether evolution is a random or ordered process When ...

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 ...
