3. Art and Culture: The Late Paleolithic period saw the emergence of symbolic thinking, evidenced by cave paintings, carvings, and ornaments. Sites like Lascaux and Altamira reveal intricate depictions of animals and human figures, suggesting a rich cultural and spiritual life.

Mesolithic Period (10,000 BCE – 5,000 BCE)

The Mesolithic, or Middle Stone Age, was a transitional period between the Paleolithic hunter-gatherer lifestyle and the Neolithic agricultural revolution. This era witnessed:

1. Microliths: Smaller, more refined stone tools became prevalent. These microliths were often used as barbs in composite tools and weapons.
2. Domestication: The gradual domestication of plants and animals began. This period saw the domestication of the dog, an important companion and hunting aid.
3. Settlement: People started to form semi-permanent settlements, often near rivers and coastlines, indicating a shift towards a more sedentary lifestyle.

Neolithic Period (5,000 BCE – 2,000 BCE)

The Neolithic, or New Stone Age, marked a profound transformation in human society with the advent of agriculture. Key aspects of this period include:

1. Agriculture: The domestication of crops like wheat, barley, and rice allowed for the establishment of stable food sources. This agricultural revolution supported larger, more permanent settlements.
2. Domestication of Animals: Livestock such as sheep, goats, cattle, and pigs were domesticated, providing meat, milk, wool, and labor.
3. Pottery and Weaving: The invention of pottery facilitated food storage and cooking, while weaving allowed for the production of textiles.
