Yes, people just like us lived through the ice age. Since our species, Homo sapiens, emerged about 300,000 years ago in Africa, we have spread around the world. During the ice age, some populations remained in Africa and did not experience the full effects of the cold.
Besides the fact it would be an awful lot colder, huge regions where hundreds of millions of people live would become completely uninhabitable. They'd be covered in thick ice sheets and subject to an inhospitable climate.
Humans during the Ice Age first survived through foraging and gathering nuts, berries, and other plants as food. Humans began hunting herds of animals because it provided a reliable source of food. Many of the herds that they followed, such as birds, were migratory.
The last Ice Age was during the palaeolithic and early Mesolithic periods of human history, beginning 100,000 years ago and ending 25,000 years ago, By the time it was over, homo sapiens were the only human species to have survived its brutal conditions.
Genetic studies of modern human DNA tell us that at some point during this period, human populations plummeted from more than 10,000 breeding individuals to as few as 600. Homo sapiens became a highly endangered species; we almost went extinct.
Endangered Species: Humans Might Have Faced Extinction 1 Million Years Ago. New genetic findings suggest that early humans living about one million years ago were extremely close to extinction.
The overall trigger for the end of the last ice age came as Earth's orientation toward the sun shifted, about 20,000 years ago, melting the northern hemisphere's large ice sheets. As fresh meltwater flooded the North Atlantic Ocean, the Gulf Stream weakened, driving the north back into the ice age.
From around 150,000 to 130,000 years ago, Africa experienced colder and more arid than present conditions. About 130,000 years ago, a warm phase moister than the present began, and this lasted until about 115,000 years ago, with greater rainforest extent and the deserts almost completely covered with vegetation.
During the Ice Age, hunting and fishing would have been the main source of food for humans, as there wouldn't have been many fruits, seeds, or other plant parts available due to the cold climate. Humans hunted large animals, like the woolly mammoth and mastodon.
Will we enter into a new ice age? No. Even if the amount of radiation coming from the Sun were to decrease as it has before, it would not significantly affect the global warming coming from long-lived, human-emitted greenhouse gases.
Early modern humans dressed for ice age success – Neanderthals, not so much. An analysis of animal remains at prehistoric hominin sites across Europe suggests modern humans clad themselves in snug, fur-trimmed clothing, while Neanderthals probably opted for simple capes.
Nowadays we can stay indoors, pop on an extra layer or snuggle under a blanket when we're chilly in the winter, but how did prehistoric humans stay warm? Well, a new study has revealed the earliest Homo sapiens used bear skin to help them stay cosy in the harsh winters.
In general, it is felt that ice ages are caused by a chain reaction of positive feedbacks triggered by periodic changes in the Earth's orbit around the Sun. These feedbacks, involving the spread of ice and the release of greenhouse gases, work in reverse to warm the Earth up again when the orbital cycle shifts back.
We are technically still in an ice age.
The current ice age started just over two and a half million years ago, and it hasn't quite ended yet. Within a single ice age, there are periods of warmth where glaciers melt, which are called interglacial periods. The opposite, when glaciers spread, is called glacial cycles.
Earth is currently in an interglacial, and the last glacial period ended about 11,700 years ago. All that remains of the continental ice sheets are the Greenland and Antarctic ice sheets and smaller glaciers such as on Baffin Island.

The first major evolutionary change in the human diet was the incorporation of meat and marrow from large animals, which occurred by at least 2.6 million years ago.
One of the warmest times was during the geologic period known as the Neoproterozoic, between 600 and 800 million years ago. Conditions were also frequently sweltering between 500 million and 250 million years ago.
In New Zealand, we call the most recent ice age the Ōtira Glaciation; at its peak, 16–18,000 years ago, the sea was about 120 metres lower than it is today. At that time much of the seabed around the New Zealand coast was dry land and coastal plains extended across what is today the inner continental shelf.
Most of Canada and Northern Europe was covered with large ice sheets. The U.S. was a mix of ice sheets, alpine deserts, snow forests, semi-arid scrubland and temperate grasslands. Areas that are deserts today—like the Mojave—were filled with lakes. The Great Salt Lake in Utah is a remnant from this time.
The last Glacial Maximum (LGM) occurred between 25-16 thousand years BP. There is strong evidence that humans had occupied Australia 45,000 aBP (1).
The melting ice sheets reconfigured the planet's wind belts, pushing warm air and seawater south, and pulling carbon dioxide from the deep ocean into the atmosphere, allowing the planet to heat even further.
It might seem completely off-base to imagine that the heat-trapping gases emitted by humans could cause “global freezing” rather than “global warming.” But in fact, scientists have long hypothesized that greenhouse gases could cause cooling in some places and warming in others due to changes in ocean circulation.
