Not Climate Change, This Ancient Animals Extinct Because of Human Death

Not Climate Change, This Ancient Animals Extinct Because of Human DeathCanberra – The giant mammal beings on earth, which lived 45,000 years ago, were initially thought to be extinct due to climate change.

However, it is now known, human beings are responsible for the extinction of a giant group of animals called megafauna, in Australia.

Megafauna began to decrease in number when humans were present in Sahul, Australia.

Professor Michael Bird, of James Cook University, Queensland, says that massive manhunts are the most likely cause of the extinction of megafauna, quoted by the Daily Mail.

"We found that the climate did not result in anything unprecedented, while the link between human existence and the extinction of megafauna is very close," wrote Professor Bird in a paper released Friday, February 12, 2016.

"Currently, the Sahul land has no local animal measuring more than 40 kg, but in the Pleistocene period, there was a vertebrate animal weighing up to 3 tons, with massive killings suggesting that humans hunted the animals to extinction."

Sahul land is now divided into mainland Australia, Tasmania and Papua New Guinea.

Megafauna Australia is in the Pleistocene era, 1.8 million to 45,000 years ago. Among the animals, there were two meters of wombat-like creatures, weighing three tons, twenty-three-pound kangaroos, and a giant, flying bird.

Bird said, "Scientists do not necessarily say that humans came and mass murdered all animals."

However, when the population changes, things like hunting, taking eggs, and killing animals are easy and can have an effect on everything.

The paper could have been considered controversial, as it broke the old notion that an increasingly dry climate was the cause of animal extinction.Bird said the 16 experts working in the paper combine physical evidence with a known climate record from the period and history of human migration to the Australian continent.

The paper is published in the journal Proceedings of the Royal Society B.
