New Fish Fossil Reveals How Fins May Have Become Hind Limbs
2014-01-14 06:11:22

[ Watch the video: Tiktaalik roseae fossils reveal evolution of hind limbs ] April Flowers for redOrbit.com - Your Universe Online The evolution of hind legs actually began as enhanced hind fins, according to the newly discovered, well-preserved pelvis and a partial pelvic fin from Tiktaalik roseae—a 375 million-year old transitional species between fish and the first legged animals. The findings, published in Proceedings of the National Academy of Sciences (PNAS), challenge the...

Genome Of The Coelacanth Sequenced
2013-04-18 05:26:08

April Flowers for redOrbit.com - Your Universe Online The genome of the coelacanth, a creature with an evolutionary history that is both enigmatic and illuminating, has been decoded by the Genome Center of the Broad Institute of MIT and Harvard, and analyzed by an international team of researchers. The findings of this study are published in the journal Nature. The coelacanth, a sea-cave dwelling, five-foot long fish with limb-like fins, was once thought to be extinct until a living...

African Lungfish Research Hints At New Evolutionary Step
2011-12-13 13:44:14

Researchers have revealed that the African lungfish can use its thin pelvic limbs to propel itself forward. The team's discovery reshuffles the order of evolutionary events leading up to creatures being able to walk, and also suggests that fossil tracks long thought to be the work of early tetrapods could have been produced instead by lobe-finned ancestors of the lungfish. "In a number of these trackways, the animals alternate their limbs, which suggested that they must have been made...

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 tetrapods–four-legged creatures, and our distant ancestors–that made the first small steps on land some 400 million years ago. A team of Australian scientists led by Professor Peter Currie, of the Australian Regenerative Medicine Institute at Monash University, and Dr...

By Friedman, Matt; Blom, Henning ABSTRACT- A new actinopterygian, Cuneognathus gardineri new genus and species, is described from the Devonian (Famennian) Obrutschew Bjerg Formation of East Greenland on the basis of multiple incomplete specimens. Cuneognathus most closely resembles Limnomis from the Famennian Catskill Formation of Pennsylvania, and, like that taxon, is known exclusively from freshwater deposits. A cladistic analysis with an ingroup of 13 actinopterygians and an outgroup...

West African Lungfish, Protopterus Annectens
2012-12-25 12:16:41

West African Lungfish thrive in fresh water in the West African countries of Senegal, Niger, Gambia, Volta and Chad basins, where the water temp ranges from 77 to 86 degrees. They also can be found in tributaries of the Chari River in Western Sudan. It is eel-like in looks with a long slender body containing 34 - 37 pairs of ribs. The body can be 9 - 15 times the length of its head with small eyes and a prominent snout. The pectoral fins (fins on each side closest to the head) are fringed...

Marbled Lungfish, Protopterus Aethiopicus
2012-12-25 12:06:57

The marbled lungfish is found mainly in the Nile river, in the northeastern continent of Africa. It also is found in such lakes as the Albert, Edward, Tanganyika, Victoria, Nabugabo, No and Kyoga, all centrally located in Africa at the southern end of the Nile. They live in the shallow areas of these lakes, streams, rivers, and swamps. During the dry season, many of the areas will dry up and when this occurs the marbled lungfish will bury themselves in the mud leaving just a small opening...

South American Lungfish, Lepidosiren paradoxa
2009-07-03 19:14:46

The South American lungfish (Lepidosiren paradoxa) is found in slow-moving waters and swamps of the Amazon, Paraguay, and the lower Parana River basins in South America. This fish is a member of Lepidosirenidae family and is noted for its necessary air-breathing. Little information is known of the South American lungfish. Common names of this species are the Scaly Salamander-fish and the American Mud-fish. Young South American lungfish are black and spotted with gold. The adult fish fades...

The Queensland lungfish, Neoceratodus forsteri, also known as Burnett salmon and Barramunda, is the sole member of the family Ceratodontidae, and one of the only six lungfish species that remain. Olive or dull brown in color, it grows to about 59.06 in (150 cm) in length, more commonly 39.37 (100 cm). It is native to the Burnett and Mary River systems of south-east Queensland, but has been introduced into other nearby rivers, including the Brisbane River. It prefers still or slow-flowing...
