New Fish Fossil Reveals How Fins May Have Become Hind Limbs

[ 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...

Common genetic recipes pattern organs as different as shark gills and human hands A SCUBA expedition in Australia and New Zealand to find the rare embryos of an unusual shark cousin enabled American and British researchers to confirm new developmental similarities between fish and mammals. Elephant fish, a relative of sharks, utilize the same genetic process for forming skeletal gill covers that lizards and mammals use to form fingers and toes, researchers at the University of Chicago and the...

The genetic toolkit that animals use to build fins and limbs is the same genetic toolkit that controls the development of part of the gill skeleton in sharks, according to research to be published in Proceedings of the National Academy of Sciences on March 23, 2009, by Andrew Gillis and Neil Shubin of the University of Chicago, and Randall Dahn of Mount Desert Island Biological Laboratory. "In fact, the skeleton of any appendage off the body of an animal is probably patterned by the...

Analyzing a fish/amphibian intermediate species or human beings' genetic code can uncover proof of evolution, scientists said at a Chicago gathering. Scientist Kenneth Miller, author of Finding Darwin's God, said at the 175th annual meeting of the American Association for the Advancement of Science that evolutionary evidence is apparent in the genetic codes of humans and non-human primates, the Chicago Tribune said Sunday. Miller theorized that both species share a number of so-called...

Some 375 million years ago, a unique fish existed with features in its head that helped pave the way for vertebrate animals to live on land, scientists said on Wednesday. Now, new research is providing the first glimpse at the internal head skeleton of Tiktaalik roseae. The transition from aquatic to terrestrial lifestyle involved complex changes not only to appendages (fins to limbs) but also to the internal head skeleton, researchers report in the recent issue of the journal Nature....

By Bell, Michael A PALEONTOLOGY Variations on a Theme YOUR INNER FISH: A Journey into the 3.5-Billion-Year History of the Human Body. Neil Shubin. x + 229 pp. Pantheon Books, 2008. $24. Ernst Haeckel's punchy three- word slogan "Ontogeny recapitulates phylogeny" has earned a certain immortality-never mind that it's wrong. Each species does not, as Haeckel claimed, retrace its evolutionary history as it develops, with human embryos going through fish and reptile stages. But that's not to say...

Even before they are born, all people carry genetic baggage, genes that were useful to distant, non-human ancestors but are hopelessly outdated, even harmful, to humans as they live today. Chicago scientist Neil Shubin calls this inheritance our "inner fish." People hiccup, he explains, because of a design malfunction in a nervous system and breathing apparatus passed down from fish and tadpoles. Human males are vulnerable to hernias because of their awkward setup for toting around...

LONDON -- Scientists have caught a fossil fish in the act of adapting toward a life on land, a discovery that sheds new light one of the greatest transformations in the history of animals. Scientists have long known that fish evolved into the first creatures on land with four legs and backbones more than 365 million years ago, but they've had precious little fossil evidence to document how it happened. The new find of several specimens looks more like a land-dweller than the few other fossil...
