Global late Quaternary megafauna extinctions linked to humans, not climate change
Royal Society Publishing ^ | May 13, 2014 | Christopher Sandom, Søren Faurby, Brody Sandel and Jens-Christian Svenning

Posted on 06/09/2014 4:13:04 AM PDT by Paul46360

"A new study led by Jens-Christian Svenning of Aarhus University has strongly suggested that humans are squarely responsible for the disappearance of megafauna during the last 100,000 years. The results have been published in the Proceedings of the Royal Society B."

Specifically, it was white males that did it.

Thank you, humans.

Here is the key takeaway:

“While there are invariably going to be animals lost after a great climate change such as the ending of an ice age, the loss of megafauna that followed the most recent glacial event is an anomaly when compared to the ending of other ice ages.”

There is one difference. Homo Sapiens. They weren’t around at the end of any earlier ice ages than the last one, commonly called the Wurm or Wisconsin Glaciation.

So all of that megafauna existed in the Americas until those Asian interlopers arrived?

I doubt this. Population levels and population density levels of ice age hunter gather people were never high enough at the time to cause a mass extinction world wide, nor did they have adequate weapons to do so.

Consider the case of the Plains Indians and the Buffalo herds. The herds grew to huge proportions but the Indians never had populations high enough to put a dent in the population.

We have a country of 300 million people , many of whom hunt and we have a hard time keeping the deer population down

Whenever I read the word “study” in a article, I become skeptical. Most of these studies are worth nothing, and are just done in order to obtain more grant money.

There were not enough humans over the past 100000 years to affect anything on the Earth.

The same is true today.

One thing these a$$hole$ don’t get. Humans are as much a part of the ecosystem as cockroaches. Humans are not unnatural. We are part of the Earth.

Why is it that these people are ashamed of being human?

It looks like “IFLScience.org” is a blog of some kind. The link looks to have been changed to the actual source, instead of the blog that you reference. Maybe the headline was changed to reflect the actual title in the source article?

Some bloggers here do that - source something, change a word or two, and then link to their blog instead of the source and act like they are doing FR a favor by linking their blog instead of the source. Kind of scummy but they do it.

Those animals have fairly high reproductive rates. Some of the large animals produce few young, and it takes a long time for the young to mature to reproductive age. Elephants, for example, gestate for two years and become sexually mature at age 14. Some of the megafauna (which were much larger than elephants) probably had even longer cycles. With such a slow reproductive rate, it would not take much hunting to disrupt the viability of the herd. Couple that with the climate changes--large body mass makes dissipating heat difficult--and they could not survive.

The title, source, link, author's name and date you used all had to be changed to reflect the original published title, the names of the study's authors, the site of original publication and the date the study was originally published.

Always use the original title, the original source, provide a link which goes to the original site of publication, provide only the name(s) of the published author(s) and the date of original publication.

However, if you prefer, we will be happy to pull this thread. Just hit the abuse button and let us know.

They were using extremely powerful assault spears with high capacity clips filled with extremely powerful “FLINT” spear points which are specifically designed to kill megafauna.

“Couple that with the climate changes—large body mass makes dissipating heat difficult—and they could not survive.”

Considering that these animals had survived numerous glacial periods prior to the anthropogenic predation period, arguably, heat stress would not be an extinction factor.

When I was studying Quaternary Geology, this was the fashionable theory, based primarily on human migration patterns as they were known at the time and the disappearance of large species. It’s a difficult case to make.

The fact is that humans have driven many species to extinction. Its not shame at being human its just what it is. More often than not they’ve been specialized populations or limited populations. Think Dodo birds, the Great Auk, Irish elk, or passenger pigeons. Hunting pressure, loss of habitat, introduction of predators, all take their toll.

On the other hand, we’ve brought some species back from the brink of extinction that were likely dying out all by themselves. The California condor doesn’t appear to have ever existed in any great numbers and would likely go extinct within a few decades if it weren’t for deliberate human intervention.

Other species like the Kirtland warbler have been brought back from the brink because of humans doing what humans do. In the 50s there were only a couple dozen breeding pairs that existed in a couple dozen square miles of northern Michigan. Today they’re found across the northern 3rd of the lower peninsula, across much of the upper peninsula and into northern Wisconsin. They rebounded because of things like logging, clearing of land for oil and gas exploration, forest fires both natural and controlled. They won’t nest anywhere but in new growth jack pines of a particular size.

We nearly wiped out the buffalo but I suspect the indians would have done the same given enough time. Running whole herds off of cliffs was a particularly wasteful means of hunting.

As far as the megafauna are concerned, my guess is that the naturally changing climate did the most damage and wiped out the most species. Humans appearing on the scene probably did finish off a few species. Its also important to note that new species arrived at the same time as humans and would have damage of their own.

I would assume the changing climate would have been the single biggest killer. Humans probably took a toll but a changing climate was inescapable.

The receding ice shelf and the changing environment that accompanied it has long been the conventional wisdom for mega fauna extinctions. The low population numbers for humans, especially in the Western Hemisphere has always made human caused extinction difficult to explain.

I suspect that other animals crossing the Bering land bridge were carrying new diseases as well. There were lots of factors but climate just couldn’t be avoided anywhere.

If you go back and look at the fossil records, you can see very substantial changes and comparatively rapid in the physical characteristics of the megafauna in response to rapid climate changes in the highly unstable warming period of the ice age.

It is very likely that the inability to adapt to rapid and radical climate swings had more to with the extinctions than human predation.

Yet there was more than one glaciation, or ice age, over the eons. Dozens just as long, just as cold, and just as quickly it became warm again. After 10,000 years or so, another ice age.

During all these many ice ages, the mammoth, the mastodon, the giant ground sloths, the Irish elk, the wooly rhinoceroses and other creatures stayed with us.

So why did they die off 10,000 years ago and not before?

Humans.

In Australia, the giant wombat, giant monitor lizard, a kangaroo over 9 feet tall, and the marsupial lion all died off about 40,000 years ago. Right around the time the first aboriginals showed up.

Even few in number, what happens if your way of hunting is to simply burn down the entire forest and eat what ever you want, already cooked? Prehistoric man had fire. There are fossil finds all over the West of mountains of bones under a cliff face—where prehistoric Indians drove the game animals. Giant bison, Saiga antelope, American camels, all a pile of bones here and there; all extinct.

Only in Africa were the megafauna not effected. And Africa, incidentally, is where humans evolved and animals in Africa have had millions of years to develop a healthy wariness of humans. The other part of the world where humans lived the longest—South and Southeast Asia, still have their megafauna, too. Indian Elephants, Indian Rhinos, tigers, panda... all learned to avoid scrawny, chatty but dangerous humans since the days of Homo Erectus.
