How to Hatch a Dinosaur

People have said to Jack Horner, he is crazy before, but it has always proved to be true. In 1982, with seven years of undergraduate work, a passage in the Marines, and a concert as a researcher paleontology at Princeton Horner got a job at Montana State University Museum of the Rockies in Bozeman. He was hired as a preservative, but soon told his bosses he wanted to teach paleontology. "They said this would not happen," recalls Horner. Four years and a MacArthur genius grant later, "they told me to do what I wanted." Horner, 65, continues to work at the museum now filled with his discoveries. He has not an academic.

As a child in the 1950s, the dinosaurs were reptiles was mainly cold, lonely animals, real monsters. Horner did not agree with this image. He saw hundreds of millions of dollars a year of sociability tips skeletons, animals living in herds, unlike modern reptiles. Then in the 1970s, searched Horner and his friend Bob Makela discovered one of the most spectacular dinosaur still a huge nesting site common duck-billed dinosaurs in northwestern Montana, with adult fossils, the young and eggs. They found evidence of many a crazy idea: parents on the site took care of their young. Judging from their skeletons, the child would duckbills were too weak to eat on their own.

Horner was to find evidence to suggest that, once born, the animals were growing rapidly (crazy idea number two) and possibly warm-blooded (that would be three) and continues to lead in searching for antiques organic matter in fossils survived intact (number four). Add in his work as technical consultant on the movie Jurassic Park and Horner has probably done more to shape the way we currently think about any paleontologist dinosaurs alive.

All this means that people are more attentive to the caller crazy these days, even when he said what he intends to do next: Jack Horner wants to make a dinosaur. Not from scratch, do not be ridiculous. He says he will do so by developing a reverse-chicken. "It's crazy," said Horner. "But it is also possible."

In recent decades, paleontologists, including Horner, found sufficient evidence to show that modern birds descended from dinosaurs, but the way they lay their eggs in the nests of the details of bony anatomy. In fact, there are so many similarities that most scientists agree that birds are really dinosaurs, the most closely related to two-legged carnivorous theropods such as Tyrannosaurus rex and Velociraptor.

However, "closely related" means something different for evolutionary biologists is needed, for example, people who write the laws of incest. Everything is relative: Humans are almost indistinguishable, genetically speaking, chimpanzees, but on this scale, they are also very difficult to distinguish, for example, bats.

Tips for long-extinct creatures, evolution of the echoes of the past, sometimes arise in the real world, they are called atavisms, one of the few people born with distinctive evolutionary antecedents. The whales are sometimes born in the contours are reminiscent of the hind limbs. Human babies enter the world, sometimes with fur, her nipples more, or very rarely, a queue itself. Horner's plan is basically to start creating a atavisms experimental laboratory. Old enough to activate the properties of a single chicken, reasoning, and you'll find something close enough to be the ancestors, "Saurus". At least that's what launched this year's TED conference, an annual gathering of the Technology, Entertainment and Design held in Long Beach, California. "When I grew up in Montana, I had two dreams," he told the crowd. "I wanted to be a paleontologist, a dinosaur paleontologist, and I wanted to have a pet dinosaur."

Already, the researchers found disturbing evidence that at least some of the old dinosaur may be activated again. Horner is the first to admit that they did not know enough to do the job himself, so he is actively searching for mates developmental biology post-doc to join his laboratory group in Montana. Horner has big ideas, and seed funding.

Now all I had to make it happen, she told the TED audience, had a couple of steps forward in evolutionary biology and genetics and all the chicken eggs that could get my hands on. "What we're trying to make is that we need to channel it, edit it, and do," he said, "chickenosaurus".
