Recreating prehistoric life is at the fore-front of interest in the scientific community. Large strides have been made in uncovering the genome sequences of Neanderthal. Within a few years, scientists hope to unravel our relatives’ entire genetic code. With Neanderthal cloning staring us in the face, a more seductive idea has emerged with immense support from the media.
The idea of cloning dinosaurs and other prehistoric life became popularized by the 1992 film Jurassic Park (based on Michael Crichton’s 1990 novel). Though it may have sparked new interest into the field of paleontology, it did so with deceiving inaccuracies. However, the technical fallacies of the actual dinosaurs are somewhat forgivable as it added to the film’s dramatic appeal. Velociraptor, as depicted in the film, was about the size of a grown man. In reality, velociraptor came to about the kneecap. Furthermore, velociraptor would more likely have been covered in feathers rather than the lizard-like skin portrayed in the movie. One scene shows velociraptor fogging the window of a door. This is an endothermic or warm blooded trait as it implies the dromaeosaurid’s body temperature is above the temperature of his environment. There is also no evidence of dilophosaurus bearing a neck frill, and brachiosaurus did not have the ability to chew his food in a circular motion (iguanodon was the first dinosaur to develop this technique by acquiring back molars to allow for equine or bovine-like chewing). Fortunately, tyrannosaurus remained very close to his biological authenticity, with the only paleobiological errors stemming from a lack in computer animation such as rudimentary ball and joint programs. However, the erroneous nature of the deoxyribonucle...

... in our criticism. Crichton and Spielberg made a greater effort to get things right than anyone before them. Perhaps, they did misspell “stegosaurus” in the Embryonic Storage Room, but who is paying attention? Since the release of Jurassic Park, a new interest has emerged into the field of paleontology. Without this new interest, fascinating breakthroughs such as evo devo might have remained a castle in the Mesozoic sky.

Michael Crichton’s classic novel Jurassic Park sparked controversy among scientists, excited science-fiction fans, and captivated paleontologists as Chrichton proposed the idea that dinosaurs could be cloned. The plot elicited criticism from scientists around the world, but support from others. Cloning a dinosaur was made possible in the fictional text: take some amber, fill in missing DNA, obtain an ostrich egg, keep the egg in a controlled environment, then a dinosaur is born. Unfortunately, each of the steps are of intricate design.
In the late twentieth century, the field of biotechnology and genetic engineering has positioned itself to become one of the great technological revolutions of human history. Yet, things changed when Herber Boyer, a biochemist at the University of California, founded the company Genentech in 1976 to exploit the commercial potential of his research. Since then the field has exploded into a global amalgam of private research firms developing frivolous, profit-hungry products, such as square trees tailor-made for lumber, without any sort of government regulation.
The first Neanderthal fossils found in Europe, a fragmented child’s cranium in Belgium in 1830, and an adult cranium in Gibraltar, were not immediately recognized as a divergent kind of human. Only in 1856 after a partial skeleton was found in a cave in the Neander Valley in Germany it became clear that these fossils belonged to an extinct human and our closest evolutionary relative (Hublin and Pääbo, 2006). Since then, questions about their relationship with modern humans have been fiercely debated between anthropologists. But what attracts most interest from scientists and popular media is the possibility of hybridization between Neanderthals and modern humans if, in other words, they were a genetically different specie or a single specie capable of producing offspring.
Dinosaur fossils are one of the few ways in which scientists can study the history of life on earth millions of years ago. Each new discovery is unique in its own way and provides valuable information about the past. No two finds are exactly identical; therefore, when dinosaur remains are uncovered, the possibility and excitement of new information or even a new species exists. Until the year 2000, no dinosaur has ever been found with a fossilized heart. Scientists at North Carolina State University and the North Carolina Museum of Natural Sciences discovered a sixty-six million year old Thescelosaurus with a heart.
In the early 1800’s, a new discovery that left paleontologists in awe was the fossil finding of the immeasurable amount of species of reptiles, Ichthyosaurs. Greek for “fish lizards”, these fossils were found all over the world. Because these large aquatic reptiles migrated just as whales do today, paleontologists have had the amazing advantage of collecting fascinating bone fragments throughout the past 177 years. Ichthyosaurs swam the ocean life from about 245 million until about 90 million years ago- approximately the same time dinosaurs ruled the land. The earliest Ichthyosaur fossil findings were in parts of Canada, China, Japan, and possibly Thailand. Countless fossils came from coatings of limestone produced out of the ocean-floor ooze that was predominantly superior at preserving very well facts of the creatures it digested (Perkins 2).
“...99.9 per cent of all [species] that have ever existed are now extinct.” (Benton 1) After one hundred and sixty million years of domination, the reign of the dinosaurs ended in fire and ice. Sixty five million years ago, the largest volcanoes in the history of the Earth erupted across what is now India, effectively annihilating the dinosaurs by spewing out noxious gas and ash, that effectively blocked out the sun killing off most vegetation and breaking the food chain, leaving the dinosaurs to starve. Compared to other groups of animals the dinosaurs were the most vulnerable to such a climatic event and the result was the end of the dinosaurs’ glorious evolutionary history.
In recent years, the Homo Neanderthalensis were viewed as “subhuman brutes”, but are now seen as a different species from our own (Balter 2001). The Neanderthals were a branch of the Homo genus that evolved in Eurasia at least 200,000 years ago (Fagan 2010). The first Neand...
The Question of Control as Presented in Jurassic Park According to Arnold Pacey How could one describe the relationship between humans and nature? Perhaps it is one of control, a constant struggle between the power of the elements and the sophistication of human mechanization. Could it be one of symbiosis, where man and nature coexist in relative peace? Are we, as a species, simply a part of nature’s constantly changing realm? This issue is one that philosophers have debated for centuries. Where does mankind fit into the vast network of interacting environments and beings called nature? From the beginning of time, we have attempted to set ourselves apart from the rest of Earth’s creatures. Given the ability to reason, and to feel, and most importantly, to choose, we find ourselves with "the impulse to master and manipulate elemental force" (Pacey 86). We must fight, we must advance, and we must control all these elements of the natural world. But just how much of that world do we control? Surely people attempt and perceive control over nature, but do they succeed? The question of control, over nature in specific, is one of the prevalent themes that runs through Michael Crichton’s Jurassic Park. This novel is set on a small island off the coast of Costa Rica called Isla Nubar. On this island, construction of a new, virtuostic, state of the art park is almost complete, when a gathered team of paleontologists, businessmen, and a mathematician arrive to approve of the park opening. All seems well until the "experts" lose control of the park, leaving the main attractions, genetically engineered dinosaurs, free to roam and hunt. This loss of control further contributes to the downward spiral the park experiences, resulting in numerous deaths. How, one might ask, could a team of technicians and experts let something like this happen? The answer is simple. They over-estimated their perceived sense of control over one of the world’s most unpredictable forces… nature. The theme of man’s perceived control over nature is one that Crichton has masterfully incorporated into his novel. The actions of the park experts present to the reader the false idea "that the proper role of man is mastery over nature" (Pacey 65). Mankind has always attempted to achieve this mastery, and the construction of Jurassic Park is a perfect example. Crichton uses the character of Ian Malcolm to constantly present this theme.
This recent discovery has left scientists with many questions to be answered. The discovery is quite important because any research up until now has failed to uncover any evidence that would reveal that dinosaurs fed among their own kind. Ray Rogers whom has been leading the ten-year excavation states in the article that there are at least 14 current day animals that still practice cannibalism such as lions, komodo dragons, crocodiles, hyenas, black bears and grasshopper mice, but in contrast, any evidence of cannibalism among dinosaurs is sparse.
From the ancient bones of the Neanderthals, scientists have been able to extract small amounts of DNA. The DNA comparisons to modern humans show no relationship, implying evolutionary separation (Kunzig, 159). Some anthropologists say the small sections of DNA found are not conclusive evidence, because modern humans show just as much variation in DNA. These people point out that individuals such as the “Portugal Kid” are hybrids of Neanderthals and modern humans, showing there was gene trading. One argument against this is that there is no skull from the ‘Portugal Kid” so it is hard to compare it to Neanderthals. Also, it is known that closely related species can breed and their offspring can be fertile, but they are still separate species (Kunzig, 161).
Jurassic Park is an action packed movie based around the recreation of dinosaurs, but the dinosaurs are all female to control birth. The dinosaurs were created by DNA from preserved insects in ancient amber. Because the DNA is so old, sections of chromosomes were not there. To patch the empty spots, the scientists used frog DNA. In the movie, one of the scientists, Malcolm, says that controlling the dinosaur population by having only females will never work, and that nature will find a way around this. Sure enough in one scene Dr. Grant notices broken egg shells with foot prints walking away from them. Dr. Grant says that the all female dinosaur habitat was able to create new life due to sequential hermaphroditism.
Scientists thought that interbreeding would be a logical assumption to the Neanderthal conundrum. Unfortunately, any evidence of DNA from Neanderthals mixed with human DNA is difficult to come by because their fossils are usually tarnished upon finding. That is until Svante Paabo, and his research team from the Max Planck Institute for Evolutionary Anthropology, came across the remains of twenty-four Neanderthals and forty early humans.* All of these fossils were nearly 40,000 years old and were from Germany, Russia, and Croatia. Nine of these fossils (four Neanderthal and five human)
Jurassic Park is a book about the cloning of dinosaurs and they are used as the park entertainment on an island. In this park where dinosaurs are the attraction, not every thing will go as planed. Reading this book will teach someone how Michael Crichton feels about biological science and the cloning of extinct animals. There are things that caused the park to be unsuccessful. Dr. Malcom and Dennis Nedry where two of the parks problems, and the other was the nature of the animals.
The debate of whether dinosaurs were cold blooded or warm blooded has been ongoing since the beginning of the century. At the turn of the century scientists believed that dinosaurs had long limbs and were fairly slim, supporting the idea of a cold blooded reptile. Recently, however, the bone structure, number or predators to prey, and limb position have suggested a warm blooded species. In addition, the recent discovery of a fossilized dinosaur heart has supported the idea that dinosaurs were a warm blooded species. In this essay, I am going to give supporting evidence of dinosaurs being both warm and cold blooded. I will provide background information on the dinosaur that was discovered and what information it provides scientists.
Jurassic Park The girl shrieks as the giant tree trunk of a leg crashes down shaking the earth. Her screams are then drowned out by the prehistoric roar of the genetically engineered Tyrannosaurus Rex as it searches for prey (Crichton, 1991). Everyone remembers this scene from the best-selling novel by Michael Crichton, Jurassic Park.
