The last woolly mammoths were believed to be roaming the Earth as close as 4,000 years ago on a remote island in the Arctic Ocean, northeast of Siberia according to a study. Researchers said learning about what led to their extinction could potentially save existing species from a similar fate. According to a study, the mammoths are believed to outlive other members of their species by avoiding the environmental factors that led to their extinction. These creatures fully disappeared by about 11000 years ago.
The mammoths dominated the northern hemisphere during Earth's last ice age since 90,000 years before climate change and human hunting wiped them out to extinction. Scientists have explored mammoth skeletons and frozen carcasses everywhere from Spain to Siberia. The scientists believe that the last herd of mammoth population survived on two tiny isolated islands situated between Russia and Alaska that were isolated from the mainland due to rising levels of seas. Researchers think Wrangel Island became the last mammoth holdout. They outlived their North American and European counterparts roughly 7,000 years before going abruptly extinct.
Wrangel Island is about to 86 miles northeast of Chukotka, Siberia, a 3,000 square-mile chunk of land in the Chuckchi Sea that isolated from Asia about 10000 years ago. Radiocarbon dating of skeletons from Wrangel Island showed that the mammoth population's extinction was fairly abrupt without any warning signs. The reason behind the sudden extinction was not clear. By examining the fossilized DNA, pollen and spores scientists discovered that the St. Paul mammoths had likely run out of freshwater as their island dried up. Scientists said there is still time to save the critically endangered species. Studying the biosignatures in the remains of the last surviving mammoth and the reason behind their extinction might help conservationists to prevent critically endangered species from dying.
