In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and reproduce, naturally selecting descendants with those traits.

Chromosomal rearrangements, such as chromosome segment inversions, may affect the epigenetic landscape as well as gene expression. Different kinds of chromosome segment inversions have been found in ...

LOGAN, UTAH, USA -- Genetic variation is the ultimate fuel for evolution, says Utah State University evolutionary geneticist Zachariah Gompert. But, over centuries, that fuel reservoir gets depleted ...

A grueling road trip led to an extraordinary experiment at UConn's Rankin Seawater lab that discovered how inverted ...

Researchers have found that chunks of "flipped" DNA can help fish quickly adapt to new habitats and evolve into new species, acting as evolutionary "superchargers." ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...
