During the Middle-Late Pleistocene, one million to 10,000 years ago, more than 50 species of animal disappeared, the last to do so 46.4 thousand years from the present. The reason for the demise of the giant creatures is hotly debated. Some scientists claim that the spread of Man across the globe was the cause. This is suspect, however, because there were so few of them. Killing the odd animal would not have made a significant impact. Many believe that the end date for megafauna is incorrect. As stated above, the theory that humans killed them off by definition means that people and animals lived side-by-side for a considerable time. Evidence in Australia certainly points to this - 13 species of large animals were here on human arrival. Moreover, the people mainly relied on subsistence strategies for food. Their weapons were not very efficient. A boomerang is highly inaccurate and the range of a spear is limited. Megafauna died out over a long period of time, not all at a s...

The argument continues over whether humans were responsible for the extinction of megafauna. Giant emus, large kangaroos, marsupial lions and diprodons were destroyed by Aboriginals in Australia according to new research. This claim is based on fungi in dung of herbivores. For 130,00 years, despite dry periods, charcoal and pollen levels in dung remained the same until Aboriginals arrived. This means that climate change was not responsible for the extinction of megafauna 40,000 years ago. There is a problem with this. When Captain Cook arrived in Australia the Aboriginal population was extremely low. Forty thousand years ago there would have been only a few hundred thousand of them. How could this low number possibly destroy all of the large animals? Some megafauna would have survived in regions where Aboriginals did not go. Australia is a very large continent. It is claimed that when the megafauna died out the vegetation changed with more fires, and eucalyptus forests spr...

Humans destroy more things in the environment than climate change. This is especially the case in Australia where over the last 50,000 years people have wiped out the county's megafauna. Before Aboriginals arrived flightless birds, large reptiles and giant marsupials lived a carefree existence. Humans slaughtered the large animals in a very short period of time. More accurate dating of bones shows that megafauna died out abruptly. When the giant creatures were in large numbers there is no evidence of human tools. After the Diprotodon, Australia's largest marsupial, large kangaroos and flightless birds died out stone tools appeared. Accurate dating shows they did not exist at the same time even though they were found together at certain locations. When humans became settled the large animals were gone. The odd thing is that humans and megafauna must have coexisted for at least 5,000 years. But this is a very narrow window to find evidence of both living side by side. This gives...
