Some people would like to live for over 100 years. Why this might not be possible for humans always, it is fairly common for the Galapagos giant tortoises. The oldest reported huge tortoise is thought to have been Harriet, who's estimated to have already been at least 176 years older when she passed away in 2006 while on screen at the Australia Zoo in Brisbane, Australia. Handpicked by Charles Darwin himself when she was around five years old, even he cannot have imagined the likelihood of her outliving her individual caretakers to such a level (Franklin 45). Her longevity however, isn't unique. The huge tortoises of the Galapagos Islands have got repeatedly demonstrated an elevated lifespan because of their unique body structure, diet, and life style. The Galapagos Islands give a habitat to 1 of just two known remaining sets of giant tortoises around today (Alderton 151). Researchers speculate that smaller sized tortoises drifted to the Galapagos Islands where they discovered plentiful vegetation and virtually no indigenous predators. As time passes they evolved in to the humble, today lumbering giants which exist. The phenomenon of gigantism evolution sometimes appears in lots of island ecosystems where you don't have to cover from predators no competition for food (Orenstein 108). This insufficient predation wouldn't normally forever last. In the nineteenth century the Galapagos Islands were frequented by sailors and fishermen who coveted the new meat obtainable in abundance from the giant tortoises. These were prized for his or her quantity and capability to be kept for months at a time without food or drinking water (Hoagstrom 1623). This adaptability for drought stricken occasions is actually a direct connect to their evolution of physiology and greatly improve their convenience of longer...
