Kangaroos and prehistoric koalas are extinct because of starvation

Kangaroos and koalas (large-sized hippopotamus) of prehistoric age are not destroyed by humans but are due to changes in weather and exhaustion of food sources, medium-sized Australian scientists said.

This archaeological site was studied in the 1950s. At that time, scientists discovered human hunting tools and thought it was humans who destroyed kangaroos and koalas.

Matt Cupper, head of the research team at the University of Melbourne (Australia) explained: 'Scientists in the 1950s did not accurately identify the dates of hunting tools. They claim that they have the same period of kangaroos and koalas that exist. Since then, humans have been regarded as the cause of the disappearance of the above two species of prehistoric animals. '

Cupper's team dated dating hunting tools using carbon spectroscopy and spectroscopy methods never used by scientists in the 1950s. They concluded that people migrated to the area with kangaroos and prehistoric bears after they had been extinct for a long time.

'People cannot be the culprit of murdering kangaroos and prehistoric bears. The longest hunting tools also came into being after these two animals became extinct for about 10,000 years. These species certainly starved to death during the drought about 55,000 years ago, ' said archaeologist Jacqui Duncan.

The team plans to continue excavating a number of other sites to find out why and when many other large mammals are extinct in Australia today.
