Paleolithic.

 The Paleolithic, also known as the Old Stone Age. This is a very ancient period in history. From Greek παλαιός means -old, λίθος means -stone.

In this period lived Neanderthals, Australopithecus, cave lions, woolly mammoths, woolly rhinoceroses.

Early humans had their own culture. They lived in caves, hunted, fished, created different tools. Ancient people carved figures from clay and stones, cooked prey on fire, they used minerals.

At the end of the Paleolithic period, was the end of the last Ice Age.

Ice age.

 Ice age is a period in history of Earth. In that time climate changed on our planet. The temperature became lower in different places.

There were many ice ages: the Huronian (2.4-2.1 billion years ago), Cryogenian (850-635 million years ago), Andean-Saharan (460-430 million years ago), Karoo (360-260 million years ago), and Quaternary (2.6 million years ago-present).

During these periods landscapes and Earth's surface changed. Ice aged influenced many different things on our planet.

At the end of these events some animals became extinct, such as: saber-toothed cats, the mastodons, giant ground sloth, wooly mammoth, and other.

Homo sapiens appeared. Humans created new tools for survival in a cold climate. Also, ancient people developed agriculture.

Geology is a science of study ice age. Scientists named geologists study these important periods. They found plants and animals in large glaciers.

Neanderthals.

 Neanderthals or Neandertals (Homo neanderthalensis or Homo sapiens neanderthalensis) lived about 40,000 years ago. They were spice of humans. But Neanderthals became extinct.

They inhabited different places in Eurasia. Neandertals weren't direct descendants of modern human. These ancient people had their own look and lifestyle.

The height of Neanderthals was 160-163 centimeters. But their body parts were large. The Neanderthals lived in caves. Also, they moved to different places. 

These people maybe could speak to each other. They hunted mammoths and other large animals. The Neanderthals gave birth to children.

Ancient people had their own culture, too. They wore animal skins, made fire, and tools. The Neanderthals had usual rituals.

Homo neanderthalensis had different looks. They had unique genes. The Neanderthals could mix with other spices.

But these people became extinct. There were many different reasons for this. Changing climate and rivalry with other spices are some of them.

Home sapiens had 0.3 % and 2 % genes of the Neanderthals.

Paleontologists and anthropologists study these ancient people. They found their cave drawings. There are traces of Neanderthals in Europe, Central Asia, the middle east, North Africa, and other places.
