What if europe never existed

I am not sure we can really tell. North America was unconnected with the rest of humanity for thousands of years.

Any new visitors from Europe, Asia, Africa, etc. There was no immunity and simple illnesses were devastating. Add in the advantages of technology horses, gunpowder, etc. Related videos.

Last Mohican. Popular What Ifs. Although every species contributed to modifications almost equally, the most visible change is triggered by a species that is arguably the smartest of all -Homo sapiens or Humans.

But have you ever imagined what would the Earth look like if modern humans never existed? The foremost factor to look upon is distribution. As a result, our domestication, and the simultaneous eradication of barbaric mannerism, gave rise to limitations in nature. According to researchers, if things would not have turned out the way they did, Earth would be a massive modern-day Serengeti Ecosystem located in Africa.

In this scenario, extinct animals similar to those found in the Serengeti today — including elephants , rhinos and lions — would live across Europe. For example, instead of African lions Panthera le o , there would still be cave lions Panthera spelaea , a slightly larger species that lived in Europe up until about 12, years ago.

Meanwhile, the Americas would be home to elephant relatives and massive bears, along with unique species, like car-size armadillo relatives called Glyptodon and giant ground sloths , according to Faurby. Elephants and other large animals are pretty determined when finding food and won't stand for unnecessary obstructions.

But also, if there are a ton of large mammals, there tends to be less wooded vegetation emerging in the first place, he added. Large animals, like elephants, are known as megafauna. During the last ice age of the Pleistocene , 2.

For instance, about 38 genera of large animals went extinct in North America at the end of the last ice age, according to a study in the journal Proceedings of the National Academy of Sciences. For the past century, scientists have debated whether natural climate changes or human activities, such as overhunting, was the main cause of these large animals' decline.

A study published in the journal Nature concluded that climate change ultimately wiped out woolly mammoths Mammuthus primigenius and other Arctic-dwelling megafauna that survived the end of the Pleistocene, as the warming climate made it too wet for the vegetation they ate to survive.

Humans did, however, hunt mammoths. Scientists who think that humans were probably the key factor in their extinction, like Faurby, argue that mammoths survived climate changes before humans came along and likely could have survived to the present day were it not for the additional pressure humans placed on them.

Christopher Doughty, an associate professor and ecosystem ecologist at Northern Arizona University, models how large animals of the past and present move seeds and nutrients around through eating and defecating.

Doughty hypothesizes that without humans, elements would be more evenly distributed across the landscape. This would mean more fertile soil, which would cause ecosystems to be more productive.

Humans tend to clump elements together through practices such as agriculture and the creation of fenced-off areas, so these areas become less fertile over time compared with wild systems, according to Doughty. Greater fertility means plants can allocate their resources toward more fruits and flowers, so the world could look more vibrant and feed more animals. The climate might also be different, and while it's difficult to say how humans and megafauna may have influenced climatic changes thousands of years ago with evidence obscured by time, it's much easier to judge our impact on Earth's climate today.

Through global warming , caused by activities such as the burning of fossil fuels, humans have raised the average global temperature by about 1. Earth, therefore, would have been at least that much cooler without us.
