A longstanding question in evolutionary biology is how sexual selection influences how entire genomes develop. Sexual ...

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes ...

Only a human being could make such conscious decisions. This is why the species Homo sapiens is the apex of evolution. Natural selection is at one and the same time a blind and creative process.

Each lizard is unique. Some have longer legs, others stronger jaws, and all behave slightly differently. The differences ...

Experiments like these are vital to the scientific process, but without evidence for multilevel selection in wild animals, ...

The theory of evolution is dominated by the utilitarian logic of natural selection: adapt or die, survival of the fittest.

New study shows how bird traits like gene makeup and clutch size shape evolution. This may help scientists understand ...

Most famously, he had the revolutionary idea of evolution by natural selection entirely independently of Charles Darwin. Wallace was born in 1823 in Usk - now in Monmouthshire. After leaving school he ...

Our research takes place on a South Florida island roughly the size of an American football field – assuming we’re successful in sidestepping the American crocodiles that bask in the surrounding lake.

The study showed that populations don’t lose their “evolvability,” even if conditions remain the same for many generations.

Studies have suggested that genes under strong sexual selection tend to evolve rapidly, particularly those associated with ...
