Selection drives functional evolution of large enzyme families

Researchers at Umeå University, together with researchers at the Institute of Botany, Chinese Academy of Sciences, show in a new study how natural selection drives functional evolution of a large protein family in conifer ...

Poxviruses defeat antiviral defenses by duplicating a gene

Scientists have discovered that poxviruses, which are responsible for smallpox and other diseases, can adapt to defeat different host antiviral defenses by quickly and temporarily producing multiple copies of a gene that ...

Climatic fluctuations drove key events in human evolution

Research at the University of Liverpool has found that periods of rapid fluctuation in temperature coincided with the emergence of the first distant relatives of human beings and the appearance and spread of stone tools.

Scientist finds rapidly adapting fanged frogs

(PhysOrg.com) -- Scientists led by biologist Ben Evans of McMaster University have documented the rapid adaptation of new fanged frog species on the island of Sulawesi, Indonesia.

Discovering the bigger picture in chromosomes

By mapping various genomes onto an X-Y axis, a team comprised mostly of Kansas State University researchers has found that Charles Darwin and a fruit fly -- among other organisms -- have a lot in common genetically.

Scientists reveal driving force behind evolution

Scientists at the University of Liverpool have provided the first experimental evidence that shows that evolution is driven most powerfully by interactions between species, rather than adaptation to the environment.
