How to make a chicken into a dinosaur

Washington, March 6 (ANI): In an awe-inspiring new experiment, paleontologists are attempting reverse evolution, in which they would try to recreate a dinosaur, by starting with a chicken embryo and working backward to engineer a chickenosaurus or dinochicken.

According to a report in Discovery News, such reverse evolution has been successfully performed in mice and flies, but those studies focused on re-introducing just a few bygone traits.

The dinochicken project instead has the goal of bringing back multiple dinosaur characteristics, such as a tail, teeth and forearms, by changing the levels of regulatory proteins that have evolved to suppress these characteristics in birds.

Birds are dinosaurs, so technically were making a dinosaur out of a dinosaur, said project leader Jack Horner, a professor of paleontology at Montana State University and curator of paleontology at the Museum of the Rockies.

The only reason were using chickens, instead of some other bird, is that the chicken genome has been mapped, and chickens have already been exhaustively studied, added Horner.

Although the plan seems more like a page out of the fictional Jurassic Park, Horner assured it is real and is already underway.

A number of people in a number of different places are moving forward with the project slowly and carefully, he said.

One such researcher is Hans Laarson of McGill University in Montreal, whos analyzing the genes involved in tail development and researching ways of manipulating chicken embryos in order to awaken the dinosaur within.

According to Horner, there is no danger of the proposed dinochicken escaping and populating the world with dinosaurs, since only the chickens development, and not its genome, would have been affected.

If the creature did somehow escape and could mate, the result would just be a regular chicken.

If a chicken embryo does not grow properly in the lab, or if it could not survive comfortably, Horner said, we would never let it hatch.

We now have the tools to reverse-engineer some of those constraints and produce traits that look a bit more like those ancient features, said Kevin Padian, a professor of integrative biology at the University of California at Berkeley and a curator at the UC Museum of Paleontology.

This tells us how genetics, development and evolution are related, so its tremendously important, he added.

When and if the dinochicken is created, Horner looks forward to bringing it out on a leash during lectures.

Were always looking for novel ways to get the general public interested in science, and you have to admit, it would be better than a slide show for demonstrating evolution, he said. (ANI)
