What led to extinction of mammoths?
Before we do proceed further, its’ better to have some basic ideas; it may make the subject easier for you to comprehend.
A mammoth is any species of the extinct genus Mammuthus. These proboscideans are members of Elephantidae, the family of elephants and mammoths, and close relatives of modern elephants. They were often set with long curved tusks and, in northern species, a cover of long hair. They lived from the Pliocene epoch from around 4.8 million to 4,500 years ago.
On other hand mastodons were large tusked mammal species of the extinct genus Mammut found in Asia, Africa, Europe, North America and Central America from the Oligocene through Pleistocene, 33.9 mya to 11,000 years ago. Now there is a question and it is with regard to their extinctions. Never consider this as trivial since researchers are still at a loss in his regard.Till a few days back a considerable section of researchers presumed that meteors were solely responsible for the extinctions but a novel study into the North American landscape 15,000 years ago has demystified a number of theories regarding why giant sloths, mastodons and mammoths died out.
The study took place under the aegis of researchers from the University of Wisconsin-Madison and they went through extensive analysis on fossil pollen, charcoal and dung fungus spores in an Indiana lake to give an idea of population density. In accordance with them, the decline of the large mammals started about 14,800 years ago, and was almost complete a thousand years later.
"About 13.8 thousand years ago, the number of [fungus] spores drops dramatically," said co-author Jacquelyn Gill. The finding, without a doubt, is highly important as these dates eradicate several possible reasons for the mass extinction.
One of these theories is that the spreading of trees on account of a changing climate resulted in umpteen damages. However, as per Gill, the disappearance of the big mammals forewent this change - and may even have helped bring it about. With the large plant-eaters out of the picture, the trees were free to take possession of the countryside.
The other theories of extinction like culpability of meteors or Clovis culture humans have also been bushed aside. What were the real causes of extinction then?
Researchers are still stumped.
