Jurassic park trex dinosaur12/28/2023 ![]() ![]() ![]() Įven without direct skin analysis, current evidence says dinosaurs used up more of the crayon box than historically assumed. The research has already shown high concentrations of copper and zinc, suggestive of the presence of melanin, a common pigment that all melanosomes contain. ![]() The test could reveal the shapes of cell structures called melanosomes, and different shapes are associated with different pigments, Barbi said. Though three other samples of dinosaur skin have been discovered, scientists are now, for the first time, using particle accelerators to probe the samples for pigments, said Mauricio Barbi, a physicist at the University of Regina, who discovered and is investigating the sample. In April, scientists made the remarkable discovery of intact dinosaur skin, which could reveal the hues dinosaurs came in - perhaps far beyond the green and brown traditionally portrayed. "People with enough money will absolutely do it." "We're closer and closer than we ever expected to be," he said. He predicts a cloned mammoth within 10 to 50 years. Ensuring that the elephant could bring a mammoth embryo to term poses the next challenge, but much of the science is in place - such as synthesizing long sequences of DNA and modifying cells to be pluripotent stem cells, which can turn into any cell in the body, Poinar said. Similarly, current or near-current science could repair the fragmented genetic material of mammoths using elephant templates, and implant an embryo in an elephant womb. In "Jurassic Park," scientists plugged holes in degraded dino DNA with substitutes from frogs, incubating the extinct animals' embryos in emu and ostrich eggs. The film correctly predicted the need to repair ancient DNA, which degrades over time, and use modern relatives to bring extinct babies to term. "Some thought we never would."Ĭloning a mammoth is now conceivable, Poinar said. "We completely underestimated how long it would take before we could sequence those genomes," Poinar told LiveScience. With well-preserved mammoth tissue unearthed from the icebox of Siberia and the Yukon, Poinar and colleagues have sequenced the DNA of the extinct elephant relatives. "The change in technology really sparked our ability to deep sequence these extinct species," said Hendrik Poinar, an evolutionary biologist at McMaster University in Ontario who is studying mammoth DNA. In 2005, however, the 454 Life Science Genome Sequencer made it possible to do just the sort of large-scale reads and analyses shown in the film. But no technology in 1993 could have done that kind of massive genetic analysis. In the film, a fictional educational cartoon credits "thinking machine supercomputers and gene sequencers" with reading dinosaur DNA. ![]() Last year, a South Korean and Russian team announced their goal of doing just that. Now, new genetic tools, and well-preserved specimens, could make one "Jurassic Park"-esque feat a reality: cloning a mammoth. Since then, cloning and genetic technologies have continued to advance, with some researchers turning their attention to extinct species. In 2001, scientists replicated the first endangered species - "Noah" the guar, a type of threatened ox. Next year's fourth "Jurassic Park" film, however, will keep the dinos scaly, according to reports - despite what experts say.īack when "Jurassic Park" debuted, science was still three years away from the arrival of the sheep named "Dolly," the first cloned adult animal, and a landmark in cloning technology. If he had, the raptors would have looked too different from the first film, said Jack Horner, a renowned paleontologist at Montana State University and a technical adviser on all the "Jurassic Park" films. Spielberg made a gesture toward the science by putting a few feathers on his speedy killers in that film, though not as many as the paleontologists requested. This was suspected even at the time of the 1997 sequel, "The Lost World," however. ![]()
