Fossils suggest earlier land-water transition of tetrapod
New evidence gleaned from CT scans of fossils locked inside rocks may flip the order in which two kinds of four-limbed animals with backbones were known to have moved from fish to landlubber.
Walking fish reveal how our ancestors evolved onto land
About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and ...
How the genetic blueprints for limbs came from fish
A study led by Denis Duboule shows that limbs emerged during evolution by modernisation of a preexisting DNA structure.
Fossil shows fish had sucker on its back
(Phys.org) —A 30-million-year-old fossil has revealed how remoras – also called sharksuckers – evolved the sucker that enables them to stick to other fish and 'hitch a ride'.
Why do we gesticulate?
If you rely on hand gestures to get your point across, you can thank fish for that! Scientists have found that the evolution of the control of speech and hand movements can be traced back to the same place in the brain, which ...
Scientists confirm theory regarding the origins of the sucking disc of remoras
Remora fish, with a sucking disc on top of their heads, have been the stuff of legend. They often attach themselves to the hulls of boats and in ancient times were thought to purposely slow the boat down. ...
Naval activity may contribute to porpoise strandings
(Phys.org) —Sonar used by the navy may cause porpoises to get trapped in fishing nets and killed, according to a recent study.
Sexiness doesn't always have a downside
(Phys.org) —University of Queensland researchers have found that sexiness doesn't have to be a burden, at least not if you're a male threadfin rainbowfish.
Father of flying fish found in China, palaeontologists say
Palaeontologists in China say they have found the world's oldest flying fish, a strange, snub-nosed creature that glided over water in a bid to evade predators some 240 million years ago.
Two new species of fish found able to regenerate a lost fin
Lungfish provides insight to life on land
A study into the muscle development of several different fish has given insights into the genetic leap that set the scene for the evolution of hind legs in terrestrial animals. This innovation gave rise to the tetrapodsfour-legged ...
How fish swim: Imaging device shows contribution of fins
There are fish tales and then there are fish tails. And a report from Harvard researchers in the current issue of the journal Biology Letters seems to demonstrate that previous theories about how bony fish mo ...
Harbor seals' whiskers as good at detecting fish as echolocating dolphins
When a hungry harbour seal sets off in pursuit of a fish diner, the animal has a secret weapon in its tracking arsenal: its whiskers. Detecting hydrodynamic trails in water with their sensitive whiskers, seals ...
Global fishing threatens endangered sharks
Western Australian researchers are conducting a global initiative to evaluate the importance of sharks for conservation and economic development, in a bid to slow global declines in shark numbers.
