In Jurassic Park, scientists resurrect long-extinct dinosaurs after discovering dinosaur blood inside a prehistoric mosquito trapped in amber. Although most real-life scientists question the plausibility of this method for bringing back long-dead species, this has not stopped researchers from exploring how to bring an organism back from extinction. Dr. Jack Horner wrote an entire book called How to Build a Dinosaur, where he describes an approach that he believes would allow him to produce a partially reconstituted dinosaur.
In recent reports, a group of scientists is attempting to bring back a more recent partially extinct species: the African white rhinoceros.
Kaziranga National Park in Assam, India is home to two-thirds of the world’s Indian rhinoceroses. When the park was started about 100 years ago, only a few of the species remained. Now there are more than 2400 at the park, despite a black market value of between $60,000 and $300,000 for just one kilogram (2.2 pounds) of rhino horn.
