In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

The researchers identified regions with Neandertal ancestry in over 300 individuals. They assessed sharing of segments, inferred gene flow, and looked at variation to identify candidates for positive ...

Giraffes are a beautiful and powerful example of what adaptive evolution can achieve. However, in recent years they have attained notoriety for a completely different reason: it has been suggested ...

Esvelt’s entanglement with evolution began early. As a child, he visited the Galápagos, and was captivated by the islands’ stunning array of unique wildlife. “That sparked an interest in the evolution ...

Scientists explored the evolutionary success of leaf beetles, the most diverse herbivores on Earth. They showed that symbioses with bacteria have evolved repeatedly and independently in different ...

Directed evolution is a laboratory technique that mimics natural selection and allows scientists to evolve genes and the ...

A study published in Nature Ecology & Evolution reveals a surprising evolutionary insight: sometimes, losing genes rather than gaining them can help bacterial pathogens survive and thrive. The study ...

The recombination between parental chromosomes, a characteristic of sexual reproduction, plays a crucial role in evolution. In mammals, a protein called PRDM9 is essential for this process. In a paper ...

Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Researchers have identified a genetic variant that contributed to the ...
