What If The Ice Age Never Happened?

An Alternate historyWhat If The Ice Age Never Happened?
An ice age may be a period of time where the temperature of the surface of earth drastically drops, leading to the enlargement of polar ice sheets as well as glaciers.

There has been a minimum of five major ice ages over the course the four.6 billion years our planet has been in existence.

The last ice age happened during the Pleistocene epoch, that happened 2.6 million years and only concluded around 11700 years ago.

what causes an ice age

During this time, our planet was covered by large glaciers. That’s an extremely huge chunk of time that our earth was one giant spherical popsicle. Sorry flat earthers.

But what if the ice age never happened in the 1st place? How would that have changed the course of the history of our planet? That’s the question we’re asking right now, on whatifhub.

Hello and welcome back to whatifhub.com, the website that asks the fundamental questions of life, and occasionally answers them too.

No one knows why the last ice age began. Scientists believe it could have been a number of factors from changes in ocean current to the composition of the atmosphere to changes in the position of the earth in relation to the sun.

During this time period, the average temperature was earth was at between 5 to 10 degrees Celsius colder than current temperatures. A huge chunk of North America, Antarctica, Europe, South America and small areas of Asia were completely covered in ice.

In North America specifically, the glaciers stretched across Greenland and Canada, and even down to some parts of America. Some of these glaciers still remain in Greenland and Antarctica.

what happened after the ice age

Interestingly, without the ice age, there’s a huge chance that humans wouldn’t exist at all. Humans first emerged during the Pleistocene Epoch.

Without it, it can be reasonably assumed that humans probably wouldn’t have evolved from Neanderthals.

Scientists think that There's a huge link between human behavior and evolution and drastic changes in climate. Somewhere between 3 and 2.5 million years ago, the first members of the homo genus emerged. They had bigger brains.

Between 2 to 1.5 million years ago, we start to see homo erectus. This was during the ice age.

Homo erectus had even bigger brains and a skeleton similar to our own. They started creating more sophisticated tools like double bladed axes. Homo erectus then started to leave Africa and migrate to other areas of the globe.

Scientists believe that a huge factor for this evolutionary change was because the climate was undergoing dramatic shifts. Our diet also began to drastically change. Before 2 million years ago, our ancestors were eating a lot more plants in their diet.

After 2 million years ago, the homo erectus diet was almost a 50/50 split between grasses and other foods. More diverse food options could have contributed to an increase in brain size.

It can then be assumed that Without these dramatic changes in climate, humans might not have evolved into homo erectus.

what caused the ice age to end

Most animals that didn’t adapt to the changing climate and change their diet went extinct. Regardless If humans did manage to evolve, then our ancestors probably wouldn’t have migrated the same distances in search of resources.

North America might not have been inhabited by humans as early as it was. Why migrate in search of food when all the food you need is right close by? 

By the end of the Pleistocene epoch, humans were found in almost every corner of the globe. The ice age had a profound effect on human migration, yet we know very little about it.

This is because lower ocean levels that were present during the ice age are now under water. Humans used to use these migration routes to travel.

Unfortunately, because they are now underwater, Ice bridges created by the ice age would have allowed humans and other animals to migrate more easily.

Humans might have never migrated to islands, like Australia. During the ice age, birds flourished, especially birds that flew and could migrate easily.

Birds like duck, geese, eagles, and hawks. Maybe if the ice age never happened, many of these birds wouldn’t have become so numerous.

Some animals that likely wouldn’t have ever existed were creatures like the wooly mammoth, giant ground sloths and saber-toothed cats.

These creatures emerged during the ice age and were adapted to the environment. Many of these animals, of course, went extinct around 13 thousand years ago.

It should be noted that many animals went extinct because of the ice age, and perhaps many of them would have existed for far longer, if not until modern day.

There was very little vegetation variation during the ice age. Most of the types of vegetation that existed were coniferous trees like pines.

Without the ice age, it can be assumed that the planet would have been far lusher because higher temperatures would have allowed most types of plants to thrive. One last cool fact, the rise of agriculture occurred roughly 10 thousand years ago, at the end of the ice age.

If the ice age never happened, and humans did find a way to evolve, maybe agriculture would have begun much much sooner, and human history and culture would go back much further.

Of course, it's extremely difficult to predict what would have happened if the ice age never occurred. It did.
