An international team performed genetic material decay rate analysis on DNA extracted from an extinct phobia bird's bone fossil and found that although short DNA fragments may exist for 1 million years, 30 or more base pair sequences are under certain conditions With a half-life of only about 158,000 years, a scientist believes that the use of ancient DNA to reconstruct dinosaurs and other similar stories in the movie `` Jurassic Park '' is unlikely to happen. Which of the following, if true, would best refute the scientist's point of view? ['Although Jurassic Park is a science fiction movie, it must also have facts.', 'Fossil samples studied above may be "contaminated" by human DNA.', 'Environmental factors affect the decay rate of genetic materials such as DNA.', 'The sequence of the base pair sequence of the fear bird and the dinosaur is different.']
