Contrary to prevailing belief, an evolutionary analysis finds no evidence that most viruses with epidemic or pandemic ...

Researchers of the Hubei University of Medicine, China, have analyzed several mutations in different variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from mammal species that ...

A new University of California San Diego study published in Cell challenges a long-standing assumption about how animal viruses become capable of sparking human epidemics and pandemics. Using a ...

A new study by researchers at the University of Wisconsin–Madison provides the first empirical evidence connecting the chromosomal location of genes to natural selection, indicating the arrangement of ...

Considerable debate still exists bout the precise nature of the mechanisms involved in the process of natural selection. In 23 May Nature, Patrik Nosil and colleagues from Simon Fraser University, ...

There is no evolutionary signal suggesting that these viruses were being “pre-adapted” for humans prior to their outbreaks. Instead, measurable changes in selection typically appeared only after ...
