In the colorful world of avian courtship, the ruff (Calidris pugnax) is in a league of its own. Breeding in marshes and wet meadows across Eurasia, the males of this medium-sized sandpiper species are ...

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 inversions are a form of structural variation in which a segment of a chromosome is reversed end to end. By suppressing recombination, inversions can preserve advantageous allele ...

In this review, we synthesize emerging evidence from animal genomics, highlighting the functional and evolutionary consequences of translocations, chromosomal fusions, and fissions. We emphasize the ...

New research is significantly revising a widely cited evolutionary model, the Inhibitory Cascade Mode (ICM). Benjamin Auerbach, professor in the Department of Ecology and Evolutionary Biology at the ...

The program in Evolutionary Biology is designed to provide students with knowledge of macro- and micro-evolutionary processes underlying the evolution and diversification of life on Earth and an ...
