Human impact on megafauna populations is thought to have been driven by hunting ("overkill"), [4] [5] as well as possibly environmental alteration. [6] The relative importance of human vs climatic factors in the extinctions has been the subject of long-running controversy. [3]
Megafauna also play a role in regulating and stabilizing the abundance of smaller animals. During the Pleistocene, megafauna were diverse across the globe, with most continental ecosystems exhibiting similar or greater species richness in megafauna as compared to ecosystems in Africa today.
Due to the evidence that Paleoindians hunted now extinct megafauna (large animals), and that following a period of overlap, most large animals across the Americas became extinct as part of the Late Pleistocene megafauna extinctions, it has been argued by many authors that hunting by Paleoindians was an important factor in the extinctions, [90 ...
A marsupial lion skeleton in the Naracoorte Caves, South Australia. The term Australian megafauna refers to the megafauna in Australia [1] during the Pleistocene Epoch.Most of these species became extinct during the latter half of the Pleistocene, and the roles of human and climatic factors in their extinction are contested.

"Notably, the Pleistocene C. lupus from eastern Beringia, by the skull shape, tooth wear and isotopic data, is also reconstructed as a specialized hunter and scavenger of extinct North American megafauna." [42] In 2019, the severed head of the world's first full-sized Pleistocene wolf was unearthed in the Abyisky district in the north of ...
This has variously been explained as: retention of a hypothetically tall ancestral condition; higher-quality diet and nutrition due to the hunting of megafauna which later became uncommon or extinct; functional adaptation to increase stride length and movement efficiency while running during a hunt; increasing territorialism among later Cro ...
