The Gill-Oxygen Limitation Theory explains the biological reasons that force fish, particularly larger or older ones, to move poleward when the waters in their habitats heat-up due to climate change.

The paired limbs of humans, and before that the paired fins of fish, evolved from the transformation of gill arches in early fish, scientists say, presenting genetic evidence for this theory.

This anatomical peculiarity has led to the proposal that the paired limbs of humans, and before that the paired fins of fish, evolved from the transformation of gill arches in early fish. Genetic ...

Pauly's research indicates that the gill issue is a constraint, not something fish can evolve out of. This means that once their gills reach a point where the oxygen they supply cannot support a ...

WOODS HOLE, Mass., April 19 (UPI) --New genetic evidence suggests the evolutionary origins of human limbs lie in the gill arches of sharks, skates and rays. Gill arches are the collection of ...

Although more than 70 species of suspension-feeding fishes compose 25% of the world fish catch, the fluid dynamic processes enabling fish to avoid clogging of the gill-raker filter are unknown.
