Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...

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 ...

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 ...

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. But what ...

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 ...

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