Feb 17, 2021 07:54 AM EST A new study released in Nature Communication suggests that over-hunting by increasing human populations following their entrance into the Americas was not the main factor leading to the extinction of the largest animals in North America. Rather, the study suggests that based on the new statistical modeling method, the populations of rge animals in North America were reduced due to climate change, leading to a radical decrease of temperatures around 13,000 years ago. This commenced the decline and extinction of these large mammals. (Photo : Pixabay) Max Planck Extreme Event Research Group Humans may have a hand in the extinction of large animals in more complicated and indirect ways than what the they believe. Prior to 10,000 years ago, North America was home to many large creatures, such as sloths, mammoths, beavers, and glyptodons. On the contrary, most of the animals weighing over 44kg in North America 10,000 years ago, also c ....

Date Time Climate Change Likely Drove Extinction of North America’s Largest Animals New research suggests that overhunting by humans was not responsible for the extinction of mammoths, ground sloths, and other North American megafauna. A new study published in Nature Communications suggests that the extinction of North America’s largest mammals was not driven by overhunting by rapidly expanding human populations following their entrance into the Americas. Instead, the findings, based on a new statistical modelling approach, suggest that populations of large mammals fluctuated in response to climate change, with drastic decreases of temperatures around 13,000 years ago initiating the decline and extinction of these massive creatures. Still, humans may have been involved in more complex and indirect ways than simple models of overhunting suggest. ....
