What is the discovery for cooking and protection?

It's difficult to pinpoint a single "discovery" for cooking and protection, as both developed gradually over a long period of time. However, we can talk about key milestones and breakthroughs that led to these practices.

Cooking:

* The Control of Fire: This is arguably the most important discovery for cooking. Humans likely learned to control fire around 1.5 million years ago. It allowed for cooking meat, which made it more digestible and easier to consume, leading to dietary changes and ultimately, brain development.

* Cooking Techniques: Over time, people developed various cooking techniques like boiling, roasting, and baking, using different materials like clay pots and stone ovens. These advancements improved the quality and variety of food available.

* Understanding of Ingredients: Humans learned about the properties of different ingredients and how they interact during cooking, leading to the creation of recipes and culinary traditions.

Protection:

* Shelter: Humans began building shelters to protect themselves from the elements and predators. These early shelters were simple, like caves and lean-tos, but gradually became more complex, utilizing materials like wood, stone, and animal hides.

* Tools and Weapons: The creation of tools and weapons for hunting and defense also contributed to protection. This includes spears, clubs, and later, bows and arrows.

* Clothing: The use of clothing, initially made from animal skins, provided warmth and protection from the elements. This evolved over time with the development of weaving and other textile techniques.

* Social Structures and Cooperation: Humans developed social structures and cooperation, which allowed them to work together for mutual protection. This included building fortified villages and defending against threats.

Important Note: It's crucial to understand that the development of cooking and protection happened gradually across different cultures and time periods. There wasn't one single "discovery" but rather a series of innovations and advancements that built upon each other.
